Well, it's the end of week one, but there's been no shortage of dramas

:00:00.:00:11.

on Springwatch. On tonight's show, we take a close look at the

:00:12.:00:16.

extraordinary life of a fascinating insect, one that probably goes

:00:17.:00:21.

unnoticed if your gardens. And we have been out and about in the wilds

:00:22.:00:25.

of Scotland looking at this wonderful animal. From beavers to

:00:26.:00:30.

bitterns, barn owls to wildfowls, it's Springwatch!

:00:31.:00:55.

Hello and welcome to Springwatch 2014, the last programme of our

:00:56.:01:02.

first week here at the RSPB Minsmere reserve on the coast of Suffolk. We

:01:03.:01:06.

have had a fantastic week, lots of drama and exciting species. But then

:01:07.:01:11.

this is a fabulous reserve. It's a thousand hectares of a mix of

:01:12.:01:17.

habitats. We have got reed beds, open water this lakes, woodland,

:01:18.:01:24.

medium sized carnivores, a beach, the sea, elegant species like

:01:25.:01:29.

avocets and we've got oystercatchers.

:01:30.:01:33.

We have been trying to get to know some of the mammals. They have been

:01:34.:01:37.

proving a little elieus i. But last night, we saw this. This is one of

:01:38.:01:41.

our badgers. It's difficult to tell the difference between a male and a

:01:42.:01:45.

female, a sow and a bore. We think this is a female. She's got a rather

:01:46.:01:50.

narrow face, elongated body, long tail. But we are trying to find out

:01:51.:01:56.

who is living in which set. That is what we are going to try and find

:01:57.:02:00.

outful we'll keep looking at them next week. In the past, people used

:02:01.:02:04.

to think that badgers lived in a very hire actual society. The top

:02:05.:02:08.

bore and the top sow and lots of underles. But that's all beginning

:02:09.:02:15.

to change -- juling underlings. Back if February, we saw something

:02:16.:02:21.

peculiar. That's a female badger underneath and that's two other

:02:22.:02:26.

female badgers trying to get to know her very, very well indeed. Badger

:02:27.:02:31.

society is a bit more fluid than people began to think. They are more

:02:32.:02:35.

than just good friends. They are, yes. It's fair to say they are into

:02:36.:02:40.

the swinging thing because we have discovered that 5 4% that isn't part

:02:41.:02:49.

of the social group, some other badger clans will come into the

:02:50.:02:52.

territory and mate with the females. February is the time they mate. As

:02:53.:02:57.

soon as the badgers have given birth, the females come into season

:02:58.:03:08.

and then they can do what they do. Sometimes badgers take a year or two

:03:09.:03:14.

years to come into sexual maturity. The big story yesterday was a

:03:15.:03:20.

dramatic one, about the rabbit nest. We had five kids in the nest and we

:03:21.:03:24.

are now down to just these two. One was taken by a Jackdaw and two were

:03:25.:03:31.

taken by a magistrate pyre. Now, did those two survive? The drama

:03:32.:03:34.

continues and there was another attack, but it's not a completely

:03:35.:03:38.

predictable ending and we'll update you with that later on. We have had

:03:39.:03:43.

a fantastic nest for you this week, we really have. We have been excited

:03:44.:03:49.

because we have been delving our noses into the nest of a bittern.

:03:50.:03:54.

Let's go live to it now. Here it is. The light is falling and the young

:03:55.:03:58.

are sleeping. There were two young bitterns in this nest and the behave

:03:59.:04:02.

you that've seen has been quite extraordinary. Yesterday it was

:04:03.:04:08.

something straight out of League of Gentlemen, they were cannibalising

:04:09.:04:11.

one another. Something we have never seen before. Now a bit of wing

:04:12.:04:17.

exercising here. At least another 0 days before they fly, but you can

:04:18.:04:21.

see their feathers beginning to grow, you can see the Spikey bits

:04:22.:04:24.

there. Just hike her, at that stage,

:04:25.:04:38.

they'll blend into the reeds. The big question is, are the bitterns

:04:39.:04:43.

doing it for you? The bitterns this week have really done it for me!

:04:44.:04:47.

From bitterns to blue tits and we have been poised on the edge of our

:04:48.:04:51.

nest boxes waiting for the blue tits to fledge. Have they fledged? Let's

:04:52.:04:57.

have a look at the nest box live. No, they haven't.

:04:58.:05:01.

They very, very nearly have. Just before the show I thought one was

:05:02.:05:06.

going to two, it was right up at that nest box hole. Look! I mean,

:05:07.:05:12.

these chicks have been ready the go for a couple of days and we thought

:05:13.:05:18.

it was the weather keeping them in box. We have only had a bit of rain

:05:19.:05:22.

so it's surprising they haven't gone. Don't speak too soon. They are

:05:23.:05:29.

leaning out of the hole. I think there's a jolly good chance that

:05:30.:05:33.

within the next hour, we could see a live fledging.

:05:34.:05:35.

within the next hour, we could see a on Springwatch, it could happen

:05:36.:05:38.

again. They did it before, didn't they? Look at what they've been

:05:39.:05:43.

doing. They have been doing this all day, all day we have thought, they

:05:44.:05:46.

are going, no they are not, oh they are, no they are not. Look at this

:05:47.:05:49.

one poking its head out. They keep They come half way out, have a

:05:50.:06:00.

little look outdoors. The poor parents have still got to come in

:06:01.:06:04.

and feed this lot. There's nine of them in there! They are getting

:06:05.:06:08.

pretty big. If they stay in any longer they won't be able to get out

:06:09.:06:13.

that hole. I wonder what is the trigger to go, feeding weight from

:06:14.:06:18.

the parents, overcrowding from the sibling, temperature outside, you

:06:19.:06:25.

There must be something that finally triggers them to lead. There's a lot

:06:26.:06:31.

of kids like that though, isn't there, like you are 29 now, isn't it

:06:32.:06:33.

about time you left! there, like you are 29 now, isn't it

:06:34.:06:37.

We have had our cameras on the blue there, like you are 29 now, isn't it

:06:38.:06:40.

tits nest for so long, we have noticed something very curious.

:06:41.:06:45.

Right down in amongst them. Watch that parent. What is she doing,

:06:46.:06:51.

digging around in that nest? She's looking for parasites. The nest has

:06:52.:06:56.

been there for a long time and it gets thick with parasites. Watch

:06:57.:06:59.

there, that's a Neal, what is she going to do? She picks it up, does

:07:00.:07:05.

she eat it? No, she leaves the nest with I. That happened quite

:07:06.:07:09.

frequently. She's gone down, burrowed around in the nest, there

:07:10.:07:18.

she goes again. Out she goes. Those nests, having the mites, fleas, they

:07:19.:07:26.

time their life psyche toll the life of the nest so the flea in the nest

:07:27.:07:33.

will hatch out and the really clever thing is that the flea will lay

:07:34.:07:41.

eggs, they'll pupate to pupae then hatch out when spring come and wait

:07:42.:07:47.

for a new batch of chicks. If no chicks come into the nest, the adult

:07:48.:07:51.

fleas will grow and climb up around the entrance hole of the nest and

:07:52.:07:55.

they'll just hang around there. If a single bird comes along and pokes

:07:56.:07:57.

its head in to have a look single bird comes along and pokes

:07:58.:08:04.

they'll be on it bite. You have got to admire parasites, remarkable

:08:05.:08:06.

animals. People often to admire parasites, remarkable

:08:07.:08:10.

question, should we clean our nest boxes out and by that information I

:08:11.:08:15.

guess the answer is yes, you should. Not just that information.

:08:16.:08:18.

Scientists have looked at a come pore son between a parasite load of

:08:19.:08:23.

natural tree hole and that of nest poxes. Nest box are better made

:08:24.:08:32.

drier repositories for nests to be based in -- comparison.

:08:33.:08:36.

I think for the first time emphatically, you have heard it here

:08:37.:08:40.

on Springwatch, it's a better idea to clean out your nest boxes at the

:08:41.:08:44.

end of the season when the birds have foreigned. We've also found

:08:45.:08:48.

that certain species like fly catchers are more likely to choose a

:08:49.:08:52.

nest box which has had the old nest removed. Oneother thing. Nest boxes

:08:53.:08:59.

which are south facing warm up more and this increases the number of

:09:00.:09:03.

parasites in this. It seems that grey tits can predict this and

:09:04.:09:07.

they'll avoid nest boxes which are in south-facing positions. So clean

:09:08.:09:11.

out your nest, if you've got one in there and move your nest box away

:09:12.:09:16.

from a south-facing location, otherwise you won't gate any grey

:09:17.:09:20.

tits. Clean it out after the chicks have gone. Obviously. That's wise.

:09:21.:09:25.

We don't know when the blue tits with going to fledge. We'll keep our

:09:26.:09:29.

eye on them. If they do it in the next hour, we will show it to you.

:09:30.:09:35.

They could go tomorrow when we are not on air or over the weekend, so

:09:36.:09:39.

keep an eye on the webcams which are on the red button and online as

:09:40.:09:41.

well. If you have been watching, you will

:09:42.:09:56.

know that me along with Dr Chris of the ornithology institution have

:09:57.:09:59.

been tagging a bird that disappeared to Africa which is where we went too

:10:00.:10:05.

to try and find it. We missed it. It nipped over to the border in the

:10:06.:10:08.

Ivory Coast and we were stood there waving our pass pores not allowed

:10:09.:10:12.

in. Chris left the Ivory Coast and maid it back to the UK -- passports.

:10:13.:10:22.

-- mad it back into the UK. We couldn't resist the opportunity to

:10:23.:10:36.

find him one more time. Chris and I and cuckoo spotter from the BDO. We

:10:37.:10:43.

have got special permission to use a cacophony of cuckoo mating calls in

:10:44.:10:49.

the hope that we can draw in Chris. We know the bird has been

:10:50.:10:54.

transmitting from here and we are going to call it using the gadget

:10:55.:10:59.

here. I'm think we should do it in the open. If we do it in the woods,

:11:00.:11:03.

we are not going to see it. I think you are right. OK.

:11:04.:11:16.

CUCKism OO -- CUCKOO SOUND. After ten minutes, a male cuckoo

:11:17.:11:26.

comes to investigate and it's flying straight at us.

:11:27.:11:33.

Going back in. No tag though. This is not Chris, but it's a great view

:11:34.:11:35.

of a cuckoo. Then another male cuckoo arrives on

:11:36.:11:55.

the scene. This is chassic territorial

:11:56.:11:58.

behaviour -- classic. Fantastic. Absolutely fantastic.

:11:59.:12:04.

But, neither of them had a transmitter. Neither were Chris.

:12:05.:12:08.

It's so frustrating. We thought we'd try our luck just

:12:09.:12:21.

one last time. This is as good a place as any.

:12:22.:12:23.

Let's pump up the volume. CUCKOO SOUNDS.

:12:24.:12:38.

Then, just as we are about to give up hope...

:12:39.:12:44.

Last willow at the end. Got it, got it!

:12:45.:12:50.

Yes, yes, yes, that's definitely it! I just saw it.

:12:51.:12:55.

There he is, about 100 metres away. I can distinctly see the antennae

:12:56.:13:00.

which means that this is the famous Chris the cuckoo.

:13:01.:13:13.

Oh, I can't tell you, it's like the grail, this little bird has

:13:14.:13:18.

travelled thousands of miles. We are finally in its presence.

:13:19.:13:23.

I can't tell you! Oh, when you think about it, Chris,

:13:24.:13:28.

we were just so close in Ghana, so close at the Ivory Coast border.

:13:29.:13:33.

Yes. So close this morning. It's just sat up there as well giving us

:13:34.:13:36.

a fantastic view. When he turns, you can see the little bit of wire,

:13:37.:13:38.

can't you? He's off, he's off. What a fantastic achievement. All

:13:39.:14:02.

that way to finally see Chris the cuckoo, absolutely astonishing. Even

:14:03.:14:06.

more meI've been following the journey. To see Chris in the flesh

:14:07.:14:11.

like that, absolutely brilliant. Actually, we checked this morning

:14:12.:14:15.

and he's about 43 miles from where I'm standing right now in that

:14:16.:14:19.

direction. But Chris is not going to stay here

:14:20.:14:25.

much longer. He arrived here on April and Th he'll only stay here

:14:26.:14:29.

for six to eight weeks. Two years ago, he left on the 11th

:14:30.:14:34.

June. So he may leave this country while we are still on air.

:14:35.:14:40.

Of course, you can follow Chris, if you want to, and all the other

:14:41.:14:46.

cuckoos that the BTO have tagged on your computer as they head back that

:14:47.:14:51.

5,000 mile journey to Africa. Log on and follow them and all the links

:14:52.:14:55.

are on our website. Hang on a minute, why has Chris come

:14:56.:15:00.

here? In the last 25 years, we've lost about half of our cuckoos. You

:15:01.:15:05.

probably have noticed that. I just don't hear them cuckoo any more. The

:15:06.:15:10.

trouble is, intensive agriculture is not good for cuckoos, but here at

:15:11.:15:14.

Minsmere, it's great for them. Why is that? Because there's food here.

:15:15.:15:25.

What they are after is caterpillars. What they like is hairy

:15:26.:15:30.

caterpillars, some of the most socksic ones, ones that other birds

:15:31.:15:37.

may not take. See that hairy caterpillar, a cuckoo could eat

:15:38.:15:40.

that. They try to knock off the hairs and swallow the caterpillar

:15:41.:15:48.

but even then if they swallow the hairs they cough them up. Many of

:15:49.:15:53.

the caterpillars are poisonous. One of them, the Woolly Bear creates its

:15:54.:16:01.

own poison but adds it by getting it from foxgloves. I have one, believe

:16:02.:16:08.

it or not, in my pocket! I have a Woolly Bear. You can see it...

:16:09.:16:14.

it or not, in my pocket! I have a on. Excuse me! There we go. Can you

:16:15.:16:18.

see that? He is covered in the hairs. Most caterpillars look hairy,

:16:19.:16:20.

they will not do you harm but a few are very irritating. If I tap him on

:16:21.:16:30.

the nose, no, he does like me! Often they curl up into a ball, making it

:16:31.:16:36.

very hard for a cuckoo to swallow. Isn't that a beautiful looking

:16:37.:16:40.

thing? That will turn into a lovely, lovely moth one day. That is one of

:16:41.:16:46.

the caterpillars that cuckoos like to eat. There are others too, there

:16:47.:16:53.

is one called a Drinker caterpillar. A drinker Moth. The caterpillar

:16:54.:16:59.

drinks the due off the grass in the morning it is a mystery why it does

:17:00.:17:03.

that. You would think it gets the fluid from the grass it eats. But

:17:04.:17:10.

sure enough, if you see one of these, you will see it drinking the

:17:11.:17:14.

due in the morning. Gorgeous. So, that is what they are here for,

:17:15.:17:18.

food. But they are also here for something else.

:17:19.:17:19.

Chris, come and tell me something else.

:17:20.:17:27.

isn't that gorgeous, what else are they here for? There

:17:28.:17:30.

isn't that gorgeous, what else are better than the feel of a sticky

:17:31.:17:42.

isn't that gorgeous, what else are right, they come

:17:43.:17:42.

isn't that gorgeous, what else are also to breed. They are parasites.

:17:43.:17:56.

isn't that gorgeous, what else are eggs in a nest. They choose a range

:17:57.:17:58.

of nests, eggs in a nest. They choose a range

:17:59.:18:06.

reed washlers. Well, we found a reed warbler nest up the road from here

:18:07.:18:11.

with a cuckoo's egg in it. Look at this... There on the left it is

:18:12.:18:16.

slightly larger. But a remarkable match in terms of its colouring.

:18:17.:18:20.

What the scientists have found is that those species of birds which

:18:21.:18:27.

are aggressive to cuckoos, like reed warblers, if they see a cuckoo, they

:18:28.:18:35.

go berserk for it, in that instance, the female cuckoos go the

:18:36.:18:38.

go berserk for it, in that instance, it comes to producing an egg to

:18:39.:18:42.

match the host's species. Well we found the egg. Of course, we wanted

:18:43.:18:48.

to see it hatch. The cameraman went there. He waited all day but look

:18:49.:18:54.

what happened in the morning if you look down between the reed warblers

:18:55.:18:58.

there, it is the chick. It is the cuckoo chick. It hatched first.

:18:59.:19:05.

Female cuckoos hold the eggs in the overduct for a day longer than

:19:06.:19:11.

normal. So preincubating them. So when they are in the host' species

:19:12.:19:16.

nest they hatch first and there is a good reason for this.

:19:17.:19:21.

There it is... You can see the youngster in there with the eggs.

:19:22.:19:27.

He is not exactly a looker, is he? You say that but it will turn into a

:19:28.:19:33.

splendid bird in the end, isn't it? So we have seen the bird in the

:19:34.:19:37.

nest. We then wanted to see what happens next. That is that the

:19:38.:19:43.

cuckoo ejects the eggs or the young. So our cameraman waited all day. It

:19:44.:19:49.

got dark. Guess what happened? He went home. In the morning he

:19:50.:19:53.

returned to find this... Just the cuckoo chick in the nest. So at some

:19:54.:19:58.

stage in the night it managed to push all of the reed warbler's eggs

:19:59.:20:04.

out of the nest. And if you look around you can see that this, down

:20:05.:20:09.

in the water, there they are, that is the discarded eggs of the reed

:20:10.:20:16.

warbler. They are tossed out. The benefit is simple. There were five

:20:17.:20:22.

or six eggs, the female cuckoo would have laid one. Now that one chick

:20:23.:20:27.

gets all of the food that would have been spread amongst the brood.

:20:28.:20:31.

Extraordinary evolution. But the question is how does the cuckoo

:20:32.:20:38.

chick get the reed warbler eggs out of the nest? We have missed that one

:20:39.:20:43.

this time but it has been filmed before. We can see it here.

:20:44.:20:47.

There is the cuckoo chick with the ridge on its back to catch on the

:20:48.:20:54.

host' eggs. It is a bit cruel. Not cruel, that is the wrong word...

:20:55.:20:59.

Remarkable! Look at that! There it goes. The instinct to know how to

:21:00.:21:04.

get into the right position, get thing ares on the back and climb up

:21:05.:21:09.

using your wings. Sometimes they slip, tumble, it takes some time to

:21:10.:21:13.

get the eggs out. Of course we are going back to the nest to watch the

:21:14.:21:18.

progress as the chick grows into, hopefully, an adult cuckoo, you

:21:19.:21:24.

never know it could get a tag and go to and fro Africa. If you were

:21:25.:21:31.

watching last night, you will know that our fabulous Lolo was watching

:21:32.:21:36.

the otter. Tonight he is in pursuit of another. A species not seen here

:21:37.:21:44.

in the wild for 400 years but now stands a chance of coming back.

:21:45.:21:50.

For the past few years on Springwatch! We have been following

:21:51.:21:54.

the story of the Scottish beaver trail. This weekend the trial comes

:21:55.:21:59.

to an end. We have come back to find out how the beavers have been

:22:00.:22:04.

getting on. Exactly five years ago four beaver families were

:22:05.:22:09.

transported from Norway and released into the llochs of Napdale. Beavers

:22:10.:22:18.

fell trees and build damns, this means that they can alter the

:22:19.:22:23.

landscape. People are not always keen for them to stay. But we wanted

:22:24.:22:29.

to bring you the life of the beaver but it has not all gone according to

:22:30.:22:34.

plan. Filming beavers take patience and persistence. We staked out a

:22:35.:22:39.

beaver lodge for five nights in a row.

:22:40.:22:45.

But apart from a couple of brief distant glimpses, we have not had

:22:46.:22:49.

great success. The truth is, you don't get much

:22:50.:22:54.

sense of the world of these wonderful animals from above the

:22:55.:22:56.

surface. We are going to try a different

:22:57.:23:02.

approach. Now beavers do spend time on land. They fell trees for

:23:03.:23:08.

construction and food. But they much prefer life under water. That's

:23:09.:23:15.

where I'm going. It is mid-morning. I have scanned

:23:16.:23:19.

the lake and there are no beavers about. It is a perfect moment for

:23:20.:23:26.

cameraman Mark, and for me, to don the snorkel and fins and explore

:23:27.:23:29.

their watery world without disturbing them.

:23:30.:23:53.

This is the beaver lodge. There is a family of beaver in there right now.

:23:54.:24:00.

I have to tell you it is like an iceburg. You think it looks big from

:24:01.:24:05.

up here, you swim down it is massive. There must be about a

:24:06.:24:09.

tonne-and-a-half of wood in there. They are amazing engineers. There is

:24:10.:24:14.

an entrance on this is side and another on the far side over there.

:24:15.:24:18.

They have entrances under the water for a variety of reasons, one is

:24:19.:24:23.

predators. If you think in Canada, northern Europe they have wolves,

:24:24.:24:29.

bears, both of which hunt beaver. So if they come out under the water

:24:30.:24:33.

they are safe. In the northern areas it can freeze. There could be a

:24:34.:24:38.

metre of ice. It does not matter to them, the entrances are about a

:24:39.:24:42.

metre-and-a-half under the water. They can get out and freeze. Even if

:24:43.:24:48.

it freezes for six months it is fantastic. The first time I have

:24:49.:24:53.

ever been under the water to see a beaver hut. What an experience.

:24:54.:24:59.

But we wanted to go one step further.

:25:00.:25:03.

With the help of the beaver trial team we decided to stake out the

:25:04.:25:13.

lodge with underwater cameras. For five nights we put cameras,

:25:14.:25:22.

around the lodge we saw a lot of fish... Eels... A happy of mud and

:25:23.:25:34.

not much else! Here we came closer but we had staked out the wrong

:25:35.:25:44.

exit! Finally, we got our shot. We found a beaver leafing the lodge for

:25:45.:25:50.

a night of foraging. You can see how well adapted they are to an

:25:51.:25:55.

underwater life. The silver colour comes from a layer of air trapped by

:25:56.:26:02.

the fur. It acts as insulation. The massive tail powering the steamlined

:26:03.:26:12.

body through the water. -- streamlined body through the

:26:13.:26:17.

water. How fantastic was that? Next weekend

:26:18.:26:24.

is the end of the five-year reintroduction project. Next I will

:26:25.:26:29.

be catching up with the scientists who followed the animals and doing a

:26:30.:26:33.

bit of research ourselves and discovering what the future holds

:26:34.:26:36.

for the Scottish beaver. Well, it is amazing to just get that

:26:37.:26:41.

tiny glimpse of the beavers underwater world. Now you may wonder

:26:42.:26:48.

where I am. I am at our production village, which is where the

:26:49.:26:53.

production and technical team are based and near the location of a

:26:54.:26:57.

couple of our nests. This is the closest one. The pile of straw here

:26:58.:27:02.

is our rabbit's nest it provided us with a lot of drama. I know that the

:27:03.:27:07.

predation of three of the kits was a tough watch. Well the #2kr578a

:27:08.:27:12.

continues, so I am just warning you. This is what happened yesterday. --

:27:13.:27:18.

well the drama continues, so I am just warning you. This is what we

:27:19.:27:24.

found yesterday. The nest was helped to by a jackdaw with a kit. The

:27:25.:27:30.

magpie was watching followed the jackdaw and went off with two more

:27:31.:27:35.

baby rabbits. That left us with two surviving kits. Obviously they are

:27:36.:27:39.

extremely vulnerable. We wondered what would happen to them. Well, in

:27:40.:27:43.

the wee hours of the morning this is what happened.

:27:44.:27:47.

The magpie came back. He knew exactly where to go.

:27:48.:27:53.

But just keep a close look at the scene it grabs one but the mother

:27:54.:27:58.

rabbit, this is the sort of time you expect the rabbit to come back and

:27:59.:28:02.

feed the baby rabbits, chases her off. Unfortunately, it was

:28:03.:28:07.

unsuccessful. The jackdaw then comes and takes another one. That was the

:28:08.:28:12.

last remaining kit. You can see the mother chases it again. This time

:28:13.:28:16.

she is more successful. The jackdaw drops the baby.

:28:17.:28:23.

But it doesn't stop there. The magpie comes back. The chase

:28:24.:28:27.

conditions. This goes on for quite some time.

:28:28.:28:36.

Then out of nowhere... Some other adult rabbits come along to join in

:28:37.:28:42.

the battle. You can only see two there but there were actually six

:28:43.:28:46.

the battle. You can only see two rabbits in all. It is like a rabbit

:28:47.:28:51.

army. You can see the kit still blind, the eyes haven't opened.

:28:52.:28:57.

army. You can see the kit still on. The magpie does not give up. It

:28:58.:29:04.

keeps trying to get its breakfast. And the adult rabbits are still

:29:05.:29:08.

chasing it. It is absolutely incredible that the

:29:09.:29:13.

other rabbits join in. We thought that was a subordinate female, yet

:29:14.:29:17.

it is getting help from other adults.

:29:18.:29:24.

They clearly want to protect it. A lot of effort has gone into

:29:25.:29:34.

getting ting of rabbits. Weak it decides to go to the mother and have

:29:35.:29:41.

a quick feed. Then the mother sort of pushes it into safety underneath

:29:42.:29:49.

one of the vehicles. Absolutely incredible to see that. Now the

:29:50.:29:53.

mother thought that was a safe place but unfortunately that vehicle had

:29:54.:29:56.

to be moved and in the morning this is a very, very busy area with cars

:29:57.:30:03.

moving around. We took the decision to remove it from the road and from

:30:04.:30:09.

the cars and put it into the grass. That is pretty much nest protocol.

:30:10.:30:14.

We didn't put a camera tonne after that but it is very, very unlikely

:30:15.:30:20.

that little kit would survive. It would be extremely weak. I know it

:30:21.:30:24.

is sad and tough to watch but you have to look at the bigger picture.

:30:25.:30:29.

Those rabbits provide food for an awful lot of other animals. The

:30:30.:30:34.

survival rate is very, very low. It is the circle of life. I'm only a

:30:35.:30:42.

few metres away from our production village near another one of our

:30:43.:30:45.

mess. I don't know if you can see a bit of elder there with some flowers

:30:46.:30:50.

on it. Just down below it, in the brambles, there's our bull finch

:30:51.:30:54.

nest. Let's go to it live. There it is.

:30:55.:30:57.

Can't see anything. The parents aren't there. I'm slightly worried

:30:58.:31:02.

about this because I haven't seen them on the nest for a while. Let's

:31:03.:31:05.

go right in. Can't see anything there at the moment. We have been

:31:06.:31:10.

watching that nest the whole day. Let's see what's been going on. Bull

:31:11.:31:18.

finches are remarkably close in relationship, like little love

:31:19.:31:23.

birds, they fly around together, and they'll share the duties of feeding

:31:24.:31:27.

the chicks. The female is quite brown, but the

:31:28.:31:34.

males are more Gaudi. You always see them together. They won't stray far

:31:35.:31:41.

from one another at all, fabulous colour there.

:31:42.:31:45.

Passes food to the female and they both share in the duties of feeding

:31:46.:31:49.

them. Absolutely gorgeous, aren't they,

:31:50.:31:53.

Michaela. I like the fact that you are dressed like a bull finch! You

:31:54.:31:57.

dressed appropriately. You are a female one! Role reversal!

:31:58.:32:05.

There are a lot of animals that you can't help but notice a bull finch

:32:06.:32:11.

being one of them, but others tend to two unnoticed, especially inSeb,

:32:12.:32:18.

yet some have remarkable lifestyles. Every spring, our gardens play host

:32:19.:32:23.

to a strange creature. And the Natural History Museum in London

:32:24.:32:29.

gets reports of a furry flying creature.

:32:30.:32:34.

These miniature mysteries are drawn to any early spring neck tear that's

:32:35.:32:38.

on offer. On a warm day, the garden can be

:32:39.:32:41.

abuzz with them. So what are they? They appear to have the body of a

:32:42.:32:51.

bee, but the face of a giant mosquito.

:32:52.:32:58.

Actually, they are neither. These little insects are bee flies,

:32:59.:33:06.

bombilious major, to be precise. They look just like bees, but

:33:07.:33:12.

whereas bees have two pairs of wing, these only have one and therefore

:33:13.:33:15.

they are flies. Bee flies start to appear the

:33:16.:33:28.

mid-March onwards. But only on warm dies.

:33:29.:33:36.

-- days. In the cool of an early morning, it can take a little time

:33:37.:33:41.

to warm up their flight muscles. But their wings beat more than 100 times

:33:42.:33:48.

per second. They are one of the most acrobatic insects in our gardens. By

:33:49.:33:52.

mimicking bees, they are able to scare off some predators wary of a

:33:53.:33:55.

nasty sting. It's easy to see why they get called

:33:56.:34:16.

furry narwals. They reach deep for nectar within flowers.

:34:17.:34:22.

As fluffy and friendly as they appear, when it comes to raising

:34:23.:34:26.

their young, things take a darker turn.

:34:27.:34:33.

Bee flies are brood parasites, the cuckoos of the insect world. They

:34:34.:34:38.

lay eggs in the nests of grand dwelling mining bees.

:34:39.:34:48.

Tell male bee flies scan the ground for signs of their host. They are

:34:49.:34:56.

looking for Shadow toes of dark areas where there might be nests.

:34:57.:35:03.

-- shadows of dark areas. Then the female gets ready.

:35:04.:35:09.

Her body pivots, her abdomen swings and she flings an egg Into the

:35:10.:35:14.

Shadows. It's a hit and miss strategy.

:35:15.:35:20.

One the female repeat again and again in the hope that some eggs

:35:21.:35:28.

land in the right place. These furry fancies are only out and

:35:29.:35:31.

about for a couple of months a year, so make the most of them.

:35:32.:35:35.

They are one of the high lites of spring.

:35:36.:35:45.

-- highlights of spring. What a completely brilliant insect. Amake.

:35:46.:35:50.

How on earth do they know where to flick the eggs into? See the little

:35:51.:35:55.

dark cracks, I think they must be able to scent the nectar there or

:35:56.:36:00.

the honey or something, they couldn't just shower them all over

:36:01.:36:05.

the place, it's hit and miss. We should look at that again because

:36:06.:36:08.

it's very cool the way they do the flicking. Look at that! It's pretty

:36:09.:36:15.

unpredictable. Hundreds of eggs are fired in the hope that some at least

:36:16.:36:19.

will land in the bee nest. I love the action though, don't you?

:36:20.:36:27.

Yes, swings it, baby! It really is that sort of action, yes. Absolutely

:36:28.:36:31.

Yes, swings it, baby! It really is remarkable. It does something else

:36:32.:36:34.

quite astonishing before it does the flicking and it's this. It has a

:36:35.:36:39.

little dust bath. It collects fine dust in a basket of hairs underneath

:36:40.:36:45.

the abdomen. Covers the eggs and it's thought that that makes the

:36:46.:36:49.

eggs heavier so the female can flick them a little more accurately. It's

:36:50.:36:55.

so complex, isn't it? Amazing. I suppose if it's got a little bit

:36:56.:36:59.

so complex, isn't it? Amazing. I weight, it's same as throwing a

:37:00.:37:02.

Ping-Pong ball, you have got a bit more up. Yes.

:37:03.:37:10.

-- a bit more oomph. Whenner filming in slow-motion, you sometimes find

:37:11.:37:14.

things out you never Noel knew about. We think we have discovered

:37:15.:37:21.

something awesome! -- know about. That's a male bee fly. He looks

:37:22.:37:27.

drunk. Watch what he does. He goes into a complete tail spin again and

:37:28.:37:34.

again. It's almost like he dozen quite know where he is and he bails

:37:35.:37:40.

out of it. Spinning out of control. He's going to be so dizzy. He's

:37:41.:37:44.

going to go again. There he is. Incredible. Why on earth do they do

:37:45.:37:49.

it? We think that's probably... That's slowed down maybe 300 times

:37:50.:37:54.

it? We think that's probably... to actually see that. The best guess

:37:55.:37:57.

we have come up with so some kind of display for the females. Did you

:37:58.:38:02.

like it? A lot. Talking about things spinning out of

:38:03.:38:08.

control, where's Chris? And completely sloshed? ! I'll

:38:09.:38:13.

ignore that! Favnt animal, but there were lots here at Minsmere. We have

:38:14.:38:16.

been featuring some of the rarer ones. We have seen the marsh

:38:17.:38:23.

harriers, and the bitterns. There is another national rarity nesting

:38:24.:38:27.

here. It's the extraordinary stone curlew. This is a remarkable bird of

:38:28.:38:35.

open country. It likes to have no impediments to its running forward.

:38:36.:38:39.

It doesn't like to take off if it can run so it lakes rabbit greys

:38:40.:38:46.

pastures. The scientific name of this bird is paranus nukdeus which

:38:47.:38:57.

means bull nosed thick beak. It appears to have a thick knee. That's

:38:58.:39:03.

not a particularly good name because it's not actually its knee. Let me

:39:04.:39:07.

draw a bird skeleton for you. Imagine this is the hip joint. The

:39:08.:39:12.

bird has its femur, this part of our leg here going up like this. That's

:39:13.:39:16.

normally hidden under the feathers on its breast. It then has the lower

:39:17.:39:20.

part of its limb coming down here, to that point which we have called

:39:21.:39:24.

the thick knee, which goes down to the foot which is at the bottom

:39:25.:39:31.

here. So this here isn't in fact any part that's joining to a knee. This

:39:32.:39:36.

is the ankle. And this part of the limb is called the tarso metatarsis.

:39:37.:39:47.

In bird, they are greatly extended to give their leg three separate

:39:48.:39:51.

sections, so not the knee at all, not a particularly good Latin name.

:39:52.:39:58.

But these are incredible birds and we are lucky enough to have found a

:39:59.:40:04.

nest here. Earlier on, we went to see what was going on at the nest.

:40:05.:40:08.

The bird was sat very still. This gave us the opportunity to get a

:40:09.:40:12.

good close-up of its head and that extraordinary eye. The reason it's

:40:13.:40:17.

got such a large eye is because they are nocturnal, they spend a lot of

:40:18.:40:21.

time active at night looking for their food. Look at that! My

:40:22.:40:26.

question is, why is the eye yellow? There's got a be a reason for this.

:40:27.:40:30.

In some species of birds, we see different colour eyes in the sexes,

:40:31.:40:33.

males will have one colour, females the other. In other species, we

:40:34.:40:38.

notice the eye gets brighter throughout their life so it's a sign

:40:39.:40:42.

of sexual maturity. Here, it might be something else. We also know that

:40:43.:40:47.

yellow filters out blue, so perhaps it's got a yellow eye so it can

:40:48.:40:53.

filter out the blue of the skies to increase the contrast so it might be

:40:54.:40:56.

able to spot predators there. I don't know, it's just a theory, but

:40:57.:41:01.

no-one's entirely sure why these birds have bright yellow eyes.

:41:02.:41:05.

Back to the nest though. Once we started looking in more detail, we

:41:06.:41:11.

saw that one of the eggs was on the brink of hatching.

:41:12.:41:15.

They do these remarkable nest changeovers. The male is the bird

:41:16.:41:19.

with the colour wins and in comes the female. As she sits down,

:41:20.:41:26.

there's the hole in one of the two eggs, a typical size for these

:41:27.:41:32.

birds, they only have two. She settles down, continues to incubate

:41:33.:41:43.

and then, overnight, she does her work and look, there it is, still

:41:44.:41:47.

hatching. Inside the egg, the chick is

:41:48.:41:54.

communicating to her. And then, first thing in the morning, out

:41:55.:41:59.

comes one of the chicks. Look at it. It might be fluffy, but it's just as

:42:00.:42:06.

well camouflaged as that adult. Taking a few steps into its world.

:42:07.:42:11.

That's what they do if they are spotted by a predator. They freeze

:42:12.:42:16.

and lay down on the soil and they are incredibly difficult to spot.

:42:17.:42:22.

They are what we call precocial chicks, they leave the nest

:42:23.:42:25.

straightaway and begin to follow the female around. She feeds them

:42:26.:42:29.

initially. She's found a worm and she's dropping it down in front of

:42:30.:42:33.

the chick, which is taking it at the second attempt, and of course, after

:42:34.:42:38.

a few days, they'll begin to find invertebrates of their own. They

:42:39.:42:43.

like to eat beetles, grasshoppers, that sort of thing. She'll lead them

:42:44.:42:48.

across the open plain, keeping a wary eye for predators. They can be

:42:49.:42:53.

incredibly difficult to spot. What about the snail? The -- name.

:42:54.:43:00.

Goggle-eyed Glover is the name, but what about stone curlew, the more

:43:01.:43:05.

familiar name, the curlew comes from the sound it makes. Listen to the

:43:06.:43:07.

call of a stone curlew. Normally delivered at night. It's a

:43:08.:43:21.

very plain eerie call. When they -- very eerie call. The curlew part

:43:22.:43:27.

comes from the fact that this is a call very much like the common

:43:28.:43:33.

curlew. Listening to that, we sometimes take sound for granted I

:43:34.:43:37.

think. We didn't ought to. Some might have seen earlier this year

:43:38.:43:42.

the extraordinary story of a lady called Jo Millen, it was on

:43:43.:43:46.

Breakfast news when I saw it, she had been deaf since birth and she

:43:47.:43:51.

was fitted with a double cochlear implant and this is what happened

:43:52.:43:55.

when she first heard a human voice, her nurse's voice.

:43:56.:44:01.

Do you know, I watched that on Breakfast news before I went out

:44:02.:44:13.

with my doings and was genuinely moved by that. That morning walking

:44:14.:44:17.

through the woods I listened harder to everything around me to really

:44:18.:44:21.

take advantage of it. We thought if she got that sort of response to a

:44:22.:44:25.

human voice, what would Jo think if she heard bird song, the dawn Corus?

:44:26.:44:32.

We sent sound recordest Chris Watson and Jo out into the woods to give

:44:33.:44:47.

her this experience -- -- chorus. It is 4. 30am.

:44:48.:44:55.

Chris and Jo are here as the dawn approaches.

:44:56.:45:00.

Can you hear that cockerel? A cockerel? Wow! It is just the third

:45:01.:45:04.

time I have heard it. It's not long before they hear the

:45:05.:45:16.

more traditional members of the dawn chorus.

:45:17.:45:31.

That's a blackbird. That's my favourite song.

:45:32.:45:49.

It's beautiful. Another blackbird. They are all

:45:50.:45:52.

over. So, Jo, we are now surrounded by

:45:53.:46:13.

bird song. There is lots of birds all around us.

:46:14.:46:18.

You can see bare branches but up there are dozens of birds singing

:46:19.:46:26.

their hearts out. It's hard to pick out individuals,

:46:27.:46:31.

so that is why it is called a chorus.

:46:32.:46:34.

It is like the chorus. But now it is getting lighter it is

:46:35.:46:38.

getting louder. There is more and more bird song.

:46:39.:46:43.

You are right. This is really the most intense part of the dawn chorus

:46:44.:46:49.

it is actually before dawn. In fact, there is a robin right over your

:46:50.:47:04.

head, singing in the tree above. It's very high-pitched warbling.

:47:05.:47:09.

It is singing from a high point, It's very high-pitched warbling.

:47:10.:47:14.

warning other robins not to come into this territory.

:47:15.:47:34.

That's great. Another new one. That is a chaffinch. It has just

:47:35.:47:46.

woken up that bird and started to sing.

:47:47.:47:51.

Can you imagine the energy it takes? sing.

:47:52.:47:59.

To sing with that power? Yes, it is just completely different for me to

:48:00.:48:02.

hear that sound. So, Jo, it is daylight, we can see

:48:03.:48:24.

everything around us now. The dawn chorus has been and gone. It was

:48:25.:48:26.

fantastic for he to chorus has been and gone. It was

:48:27.:48:33.

you. How was it as an experience? Wow! It was an experience I have

:48:34.:48:38.

never had before. It has been absolutely fantastic. I didn't

:48:39.:48:43.

realise that there were so many different birds, you mentioned so

:48:44.:48:44.

many different birds different birds, you mentioned so

:48:45.:48:49.

And how different they all sound. I think that I could actually identify

:48:50.:48:55.

granted it is incredible. If you have never done it, I suggest you

:49:23.:49:27.

get up early one morning this weekend and enjoy it. If you have

:49:28.:49:31.

done it before, do it again, listen to it with fresh ears. We are also

:49:32.:49:37.

encouraging you to do the garden bio blitz. This is something we did on

:49:38.:49:43.

Springwatch last year. It is a blitz of your garden to see how many

:49:44.:49:47.

different species you can find it is great to do with the kids. All of

:49:48.:49:56.

the details of that are on the website at: Chris, you have brought

:49:57.:50:03.

a beautiful bird! I have indeed. We would like you to look out for these

:50:04.:50:05.

this weekend would like you to look out for these

:50:06.:50:10.

It is a barn owl. If you are lucky enough to have one near you, they

:50:11.:50:13.

are apparent, they could enough to have one near you, they

:50:14.:50:18.

in daylight as they have young. This enough to have one near you, they

:50:19.:50:22.

is a species in crisis, I'm afraid. From 1900 to 1908, they declined.

:50:23.:50:30.

Then we managed to stabilise them. The reasons for them going down in

:50:31.:50:35.

numbers is the loss of habitat and food and many young birds are hit by

:50:36.:50:41.

cars. And some thought that bacteria is building up in the bodies. So the

:50:42.:50:46.

Barn Owl Trust has launched a full barn owl survey for ten years. Find

:50:47.:50:50.

that at; If you find a nest note it. If you

:50:51.:51:05.

see a bird that is good or find a dead one or a roosting bird, we

:51:06.:51:12.

would like to know about it to get a handle on their area.

:51:13.:51:19.

It is nice to see an owl bird up close. You are so soft. Stunning.

:51:20.:51:26.

With a beautiful heart-shaped face. It endears them to people with the

:51:27.:51:32.

slightly baky nose there. And that is the equivalent of the owl ears.

:51:33.:51:37.

They rely on the hearing for hunting. This proved a problem last

:51:38.:51:42.

year, with the wet spring, they cannot hear properly to hunt. They

:51:43.:51:46.

don't like flying in the rain. When people looked at the numbers they

:51:47.:51:52.

found a 71% reduction in next occupancy. So last year was a poor

:51:53.:51:57.

breeding season for the barn owls. We are hoping that those who got

:51:58.:52:01.

through the spring will have a better breeding opportunity this

:52:02.:52:04.

year. We are encouraging you to do lots of

:52:05.:52:09.

things over the next three days, so I guess you will want to know what

:52:10.:52:13.

the weather is going to be like, not just for you but for the wildlife as

:52:14.:52:18.

well. Let's go live to the BBC Weather Centre where I am sure that

:52:19.:52:23.

Nick Miller can enlighten us. I have a forecast but it was a

:52:24.:52:29.

challenge. Prepare the forecast and watch the bluetit weather online.

:52:30.:52:34.

So, now it is looking OK, I managed both. Remember at the start of the

:52:35.:52:38.

week I had low pressure behind me. There was talk of rain. We had a wet

:52:39.:52:44.

day on Tuesday at my Minsmere. Now there is high pressure building for

:52:45.:52:47.

tomorrow and Saturday, with most places dry with a mixture of cloud

:52:48.:52:51.

and sunshine. On Sunday the weather fronts come into Northern Ireland

:52:52.:52:54.

and Scotland. A bit of rain in the west of Scotland. But there is

:52:55.:52:58.

uncertainty of how much of England and Wales will see the rain during

:52:59.:53:02.

the day. So check the forecast. Basically it is good news if you

:53:03.:53:07.

want to get out and discover the wildlife near you, listen to the

:53:08.:53:11.

dawn chorus. For the UK as a whole it is a lovely start to the weekend,

:53:12.:53:16.

some of us getting rain by Sunday. What does it mean for you at

:53:17.:53:24.

Minsmere? Well, it is mainly dry. There could be an isolated shower on

:53:25.:53:29.

Sunday night but generally great weather for the birds gathering to

:53:30.:53:34.

feed the chicks and who knows, the sight of blue sky may get the

:53:35.:53:39.

bluetits to fly the nest scroll I'll be watching.

:53:40.:53:45.

So, it has been grey and rainy and a little miserable all week, when does

:53:46.:53:50.

it brighten up? When we are off air on Friday! Tomorrow! We have one

:53:51.:53:54.

more treat before the end of the programme. Another live nest. It is

:53:55.:54:00.

a reed warbler. Let's go straight to it now. There it is. This nest has

:54:01.:54:06.

four eggs in it. It is down in the scree. Here is the incredible thing,

:54:07.:54:11.

this little bird, we have been talking about the cuckoo, this

:54:12.:54:14.

little bird will have travelled from Africa to be with us tonight. It

:54:15.:54:18.

will have travelled thousands of miles to make that tiny little nest

:54:19.:54:23.

in the reed bed. Isn't that astonishing? It looks

:54:24.:54:32.

sleepy doesn't it? She's had enough of the show! What is interesting, is

:54:33.:54:38.

that this is a host of cuckoos, a cuckoo, if it is lucky, which lay an

:54:39.:54:45.

egg in a reed warbler nest but look at what we have observed, they are

:54:46.:54:51.

very, very attentive parents. They are hardly ever off the nest. As

:54:52.:54:55.

soon as one goes, two seconds later, the other one comes in.

:54:56.:55:03.

We have been watching this and seen 11 changes in three hours. One goes

:55:04.:55:08.

off, two seconds later, the other adult pops back.

:55:09.:55:17.

And again. Off it goes, one, two... Three seconds later. So, Chris, how

:55:18.:55:22.

on earth does a cuckoo get in there to lay an egg? It is a very good

:55:23.:55:27.

question. But the cuckoos have thought about that. On average it

:55:28.:55:34.

takes six seconds for the nest changeover but ten seconds for a

:55:35.:55:39.

cuckoo to lay an egg in the nest. It does not have time. But look at this

:55:40.:55:45.

cuckoo. Over a period of time, they have evolved to look like a

:55:46.:55:49.

sparrowhawk. So when they fly in, they scare the birds off. You may

:55:50.:55:54.

think that they could look like a cuckoo and that would scare them off

:55:55.:55:58.

but if the bird is not sure, it will keep it away for longer. This give

:55:59.:56:02.

it is just enough time for the cuckoo to get in there and lay its

:56:03.:56:10.

egg. This is an example of baitsy and mime I cannery. Fabulous work

:56:11.:56:14.

from the cuckoo! I think we should take a quick look at the teasing

:56:15.:56:23.

tits. Have they left the nest? I don't think they have! They are

:56:24.:56:27.

still there. I have been keeping an IRA on the live cameras throughout

:56:28.:56:31.

the last hour, willing them to fly out of that nest hole! I don't think

:56:32.:56:36.

that they are going to go this evening. They will go in the morning

:56:37.:56:42.

and especially if we get a nice clear warm sunny morning, unlike any

:56:43.:56:48.

we have had so far this week. Of course we will update you on

:56:49.:56:55.

Monday, showing you watch them fledgeling if you have not already

:56:56.:57:01.

watched it online. But we have also had camera teams filming all over

:57:02.:57:03.

the country... Now our mission is to explore the

:57:04.:57:28.

wildlife here. We are going to try to up the ante. The night creatures

:57:29.:57:34.

proved elusive. So we are throwing new technology at it. The same for

:57:35.:57:41.

Winterwatch. Night cameras. We are hoping to explore what is going on.

:57:42.:57:47.

We have had a hot tip that there is a tawny owl making its moves. And

:57:48.:57:52.

also tantalising glimpses of this creature. What is it? Well, it is a

:57:53.:57:59.

predator, it is a stoat. We are on the trail this weekend, hoping to

:58:00.:58:03.

bring you font liesing pictures on them.

:58:04.:58:09.

And more of these, the bittern chicks. They are on the grow and

:58:10.:58:15.

moving off into the reeds. So keep your eyes on those. There should be

:58:16.:58:19.

more of them at the beginning of next week. You can watch us

:58:20.:58:25.

more of them at the beginning of Red Button and on sprung after

:58:26.:58:29.

Unthis. And we look forward to seeing you at 8.00pm on Monday. But

:58:30.:58:35.

for now, it is goodbye from us. Goodbye! Goodbye!

:58:36.:58:52.
