It was a beautiful

day here yesterday.

0:00:060:00:12

It was the warmest day of the year

so far. Typically the weather has

0:00:120:00:16

turned.

Perfect conditions if you

are a coot or aids duck -- a duck.

0:00:160:00:26

Welcome to a brand spanking new

series of Winterwatch!

0:00:260:00:37

Hello and welcome to Winterwatch,

2018. Coming to you from marvellous

0:00:540:00:59

Sherborne Park Estate in

Gloucestershire, 4000 acres managed

0:00:590:01:03

by the National Trust since 1987.

We're glad to be here because there

0:01:030:01:08

is an enormous mixture of habitats,

woodlands, rivers and a lot of very

0:01:080:01:14

wet meadows at this time of year. We

have a super series coming up, we

0:01:140:01:19

want to bring you the best of the

seasonal wildlife and the show is

0:01:190:01:23

going to start on a high because we

have special guests. Kate Bush and

0:01:230:01:27

Mark Almond!

Rulli and!

80s icons --

brilliant! We've been saying it's

0:01:270:01:36

been wet, certainly very muddy but

quite mild. It's Winterwatch and I

0:01:360:01:40

don't have a woolly hat on. Things

may change through the week. Where

0:01:400:01:47

are we? Let's have a look at the

map, we're between Cheltenham,

0:01:470:01:51

Bristol and Reading. In the heart of

The Cotswolds. That's where we were

0:01:510:01:57

for Springwatch and Autumnwatch and

it is where we ask all Winterwatch.

0:01:570:02:00

Our challenge is to try and document

the wildlife here at Sherborne

0:02:000:02:04

through the season. Let's try and

catch up with what we've seen so

0:02:040:02:09

far.

Spring started with clouds and

mayflies, flying fish and countless

0:02:090:02:17

chicks. There were highs and lows,

winners and losers.

As the seasons

0:02:170:02:25

moved into the rusty colours of

autumn, we saw a bounty of bats,

0:02:250:02:32

Randy stags and badgers with

interesting table manners!

That was

0:02:320:02:40

then. This is now.

0:02:400:02:47

UPBEAT MUSIC.

0:02:470:02:51

Oh!

It's drawn blood!

0:02:510:02:57

It's there, look.

Oh, look!

0:03:050:03:10

Oh, right in the top. A nest.

0:03:190:03:30

Looks good, doesn't it? That

hawfinch. Great stuff in this series

0:03:340:03:41

from around the UK but our mission

at Sherborne is to bug the estate

0:03:410:03:48

with cameras to see what's going on

and we have some new locations. One

0:03:480:03:51

of our cameras may be the great

Wall. Here we have a camera on one

0:03:510:03:59

of the old stone walls. Of course

they are an interesting feature of

0:03:590:04:03

the landscape and they are a good

refuge for landscape. Nothing

0:04:030:04:06

showing at the moment but what have

we seen earlier? Well, we've seen a

0:04:060:04:11

mouse. In fact we saw a wood mouse,

discernible from its large ears,

0:04:110:04:17

eyes and long tail. It is coming to

some bait which we've tempted it

0:04:170:04:23

with. These animals are using the

wall of shelter, there are plenty of

0:04:230:04:27

predators. We hope to catch a

glimpse of eight stoat hunting them.

0:04:270:04:32

Here we have a vole, trying to

determine if it was a field vole.

0:04:320:04:39

The size of the ears and the colour

of the tail, difficult to come up

0:04:390:04:43

with an answer. If you are Professor

Jimmy Vole, we'd like to know.

How

0:04:430:04:51

many different species are there?

If

you discount the Orkney vole, you

0:04:510:04:57

have the bank vole and the field

vole.

As well as a thrilling wall,

0:04:570:05:06

will we have the Woodland feeding

station. Let's go to that camera

0:05:060:05:11

now. There we are in the woods.

That's the feeding station there.

0:05:110:05:18

There's a variety of different food

we put down because we're not sure

0:05:180:05:21

what may come into the station. We

can't see a lot right now. Rather

0:05:210:05:26

lovely, like one of those

Neanderthal homes made with mammoth

0:05:260:05:31

bones.

It doesn't look comfy!

Let's

catch up with what's been going on

0:05:310:05:35

there. Look at this, do you know

what it is? About the size of a

0:05:350:05:42

large box, these are muntjac deer,

male and female. Often in pairs.

0:05:420:05:49

Quite a controversial animal, an

SKP. If you listen closely they make

0:05:490:05:54

an extraordinary sound -- escapee.

0:05:540:05:59

CHATTERING SOUND.

They are known as

barking deer, but that isn't

0:06:010:06:08

barking, not heard anything like

that. They are controversial because

0:06:080:06:14

they spread all over the country,

they started escaping in the

0:06:140:06:18

mid-20th century and they've spread

everywhere. They are very on edge,

0:06:180:06:22

the slightest thing would make them

jump. Beautiful rusty colour when

0:06:220:06:29

you see them in the wild. Oh, oh. We

think that was part of -- possibly a

0:06:290:06:37

puff of wind.

That squeaking is

extraordinary, it almost sounds like

0:06:370:06:40

my dogs!

Never heard it before, I've

heard them barking.

We can hear the

0:06:400:06:46

normal sound of the barking deer.

BARKING SOUND. It is an eerie sound.

0:06:460:06:58

I'd have a job telling that apart

from a roe deer.

It is more

0:06:580:07:05

guttural.

We are hoping to see them

tonight, either muntjac or may be

0:07:050:07:13

badgers on the thermal camera. Let's

have a look and see if the cameraman

0:07:130:07:16

has captured anything. Nothing and

the moment but we'll keep and you

0:07:160:07:21

know if we spot anything.

You may

have noticed that I'm dressed in a

0:07:210:07:26

slightly different way than usual!

Is the incontinence is reaching its

0:07:260:07:33

zenith, mate!

We've noticed

something extraordinary going on in

0:07:330:07:43

the...

Where are we? Sherborne!

The

incontinence isn't a problem but...

0:07:430:07:52

In the Sherborne book about a

kilometre away, some fascinating

0:07:520:07:55

biology going on -- Sherborne brook.

I'm going into the icy cold water to

0:07:550:08:01

show you this curious phenomenon.

I'm going to slowly limp away.

I

0:08:010:08:08

thought some icy cold water might

say they few problems!

As three are

0:08:080:08:13

in Sherborne, that's where we are,

Sherborne! Gillian is 500 miles up

0:08:130:08:18

the coast in Scotland. Let's see

where she is. You basically head up

0:08:180:08:24

north from Sherborne, you get to

Glasgow, turn left and go to the

0:08:240:08:27

inner Hebrides to Islay in the most

southern island. It's a most

0:08:270:08:33

fabulous place for wildlife and a

few good distilleries as well.

0:08:330:08:39

Welcome to the Isle of Islay. This

island is famous for its whiskey.

0:08:390:08:47

These casks are empty but in the

buildings behind me, there are

0:08:470:08:51

23,000 of these casks, that's 7

million litres of whiskey slowly

0:08:510:08:57

maturing.

0:08:570:08:59

We are having a few problems with

our outside broadcast in Islay.

0:09:010:09:07

Let's see if we can get Gillian

back. It looks like we might be able

0:09:070:09:11

to get her. Oh, we've lost her.

Earlier today we were quite canning,

0:09:110:09:17

we are canning here at Winterwatch

so we recorded the rehearsal that

0:09:170:09:20

she did, which was very good! We are

going to look at it now rather than

0:09:200:09:25

seeing her life. This is what

Gillian has been up to.

0:09:250:09:31

Welcome to the Isle of Islay. This

island is famous for its whiskey.

0:09:310:09:36

These casks are empty but behind me

in the buildings, there are 23,000

0:09:360:09:42

of these casks, that's 7 million

litres of whiskey. All slowly

0:09:420:09:46

maturing. But of course we're not

here for the whiskey, we're here for

0:09:460:09:53

the incredible wildlife.

0:09:530:09:58

the incredible wildlife. Islay. The

queen of the Hebrides. Bathed by the

0:09:590:10:07

warming waters of the Gulf stream,

Winters on this island are milder

0:10:070:10:10

than the rest of the UK, making it a

magnet for winter visitors. In their

0:10:100:10:16

thousands.

0:10:160:10:22

thousands. And it's short winter

days off are some of the best

0:10:220:10:25

chances of seeing some of the UK's

rarest and most elusive wildlife.

0:10:250:10:33

We're going to meet a lot of those

characters through the week. But

0:10:330:10:39

tonight, we're on the very northern

tip of Islay. Out in the darkness,

0:10:390:10:44

you can't see it, there are

mountains. To really get the lay of

0:10:440:10:50

the land, make sense of the plays,

we have to see it in daylight. -- of

0:10:500:10:55

the place. We're at a distillery

that was built in 1881, it's one of

0:10:550:11:02

the oldest on the island and like

all old distilleries it was built

0:11:020:11:05

right on the water. That's because

it made it easy to lower the casks

0:11:050:11:10

onto the ships that sail back to the

mainland to bottle up the whiskey.

0:11:100:11:15

The waters are also rich in

wildlife. I've been talking to

0:11:150:11:21

locals here who tell me that there

are all those that use the channels

0:11:210:11:26

and straits between the islands,

pods of dolphins -- there are orcas.

0:11:260:11:35

Posted here is one of the island's

most charming residents. And there

0:11:350:11:40

it is. We are talking about otters,

very active during the day unlike

0:11:400:11:49

their river cousins. This is the dog

otter, marking his territory. There

0:11:490:11:59

is a female, slightly smaller, who

has had some Cubs last summer and

0:11:590:12:05

they have now grown and they are

fully independent but with a lot to

0:12:050:12:09

learn still. What is absolutely

incredible is that these otters use

0:12:090:12:17

this patch of coast regularly, they

are seen in front of the distillery

0:12:170:12:21

and the slipway you can see, well,

that's exactly where I'm standing

0:12:210:12:25

now. A little bit further up the

coast, there is an overnight then.

0:12:250:12:34

-- overnight den. We had a live

camera on it, let's have a look.

0:12:340:12:40

What you can make out is some rocks,

set back from the high tide line.

0:12:400:12:46

The dark band is a whole in the rock

and to the right of the screen is

0:12:460:12:50

where we've seen otters coming and

going. We're going to keep an eye on

0:12:500:12:55

it during the show and later we are

going to talk about some winter

0:12:550:12:59

survival strategies and also how

those juveniles make it through

0:12:590:13:04

their first winter, the biggest

challenge for them. Winters in Islay

0:13:040:13:09

may be relatively mild but 200 miles

away in the Scottish Highlands,

0:13:090:13:14

cameraman Neil Anderson has captured

the essence of winter.

0:13:140:13:20

This is the height of the Cairngorms

in the Scottish Highlands. And this

0:13:310:13:38

is my home.

0:13:380:13:47

Each winter I wait eagerly for the

first falls of snow.

0:13:490:13:59

My job often involves travelling far

to find the wildlife but in this

0:14:060:14:09

season the wildlife comes to me.

0:14:090:14:17

My house is surrounded by forest and

as the snow sets in it provides a

0:14:170:14:21

welcome refuge for many species.

Driven off the exposed hillsides,

0:14:210:14:32

Red Deer seek the protection of the

trees.

0:14:320:14:37

The males were locked in combat a

short time ago but now they are

0:14:410:14:49

peacefully together. Their

magnificent antlers are now

0:14:490:14:54

redundant, the battles forgotten. In

the shelter of the woods, grading is

0:14:540:15:03

easier as the snow is then on the

ground. -- grazing is easier.

0:15:030:15:10

The forest is home to red squirrels.

0:15:140:15:22

These rodents feed on tiny buds at

the very tops of the pines.

0:15:290:15:37

They look particularly healthy

during the winter months and for

0:15:420:15:48

good reason. Winter is mating

season.

0:15:480:15:57

Males charge after females in a

dizzying chase.

0:15:580:16:07

It is thirsty work, but with the

usual supplies of water now frozen,

0:16:130:16:18

snow will have to do.

0:16:180:16:24

Much of their energy is expended on

courtship, so the squirrels are

0:16:280:16:32

always on the lookout for easy

pickings. Taking advantage of

0:16:320:16:36

anything they can find.

0:16:360:16:43

Some they immediately eat, but

others are taken away.

0:16:480:16:57

others are taken away. Nuts cast in

the forest will be a valuable food

0:16:570:17:02

supply throughout these harsh winter

months.

0:17:020:17:08

But it's not just the squirrels who

are tempted by my feeders. Amongst

0:17:120:17:20

the usual garden birds I get a

really special visitor crested tits.

0:17:200:17:34

With their punk-like hair styles,

they're unmistakable. Feisty and

0:17:340:17:43

territorial, they raise their crests

high to show dominance. They usually

0:17:430:17:51

prefer to forage among the trees and

it is often only their call that

0:17:510:17:56

gives them away.

0:17:560:18:01

But the cold of winter draws them

closer.

0:18:040:18:12

closer. They don't hang around on

the feeders for long. Eating back

0:18:120:18:17

under the cover of the trees is the

safer option.

0:18:170:18:22

Crested tits are a

0:18:220:18:31

Crested tits are a a real speciality

and only found in this part of

0:18:310:18:34

Scotland. It is winter that allows

me these intimate views, right on my

0:18:340:18:41

doorstep.

0:18:410:18:44

A cool bird - being an ex-punk

rocker yourself, hard to believe

0:18:480:18:52

now, that you look so smart - I

believe that is in your top ten.

I

0:18:520:18:58

like a crested tit because I live in

the south of England. They are not

0:18:580:19:02

top ten. They are a little scruffy

for me.

And a punk rocker isn't.

0:19:020:19:08

Some of us are relatively smart.

That is on Neil's doorstep.

0:19:080:19:13

Obviously here in Sherborne we have

plenty of wildlife on our doorstep.

0:19:130:19:18

One has been elusive - the badger.

We tried hard in Springwatch to get

0:19:180:19:22

to know it. We didn't have any luck.

We tried harder in Autumnwatch - no

0:19:220:19:28

luck. We will try and get closer to

it in Winterwatch.

In Springwatch we

0:19:280:19:35

worked with Dr Dawn Scott and

collared one of the badgers here we

0:19:350:19:42

called Madonna. She disappeared and

reappeared again, our hopes rose.

0:19:420:19:46

She disappeared again. Subsequent to

that we've had no signal whatsoever.

0:19:460:19:51

We think, because when we collared

her we identified she was an old

0:19:510:19:55

animal that she's probably died of

natural causes underground. That

0:19:550:19:58

means we have not been able to

record what she's been getting up

0:19:580:20:02

to. Subsequent to that, Dawn has

been back and we collared three more

0:20:020:20:08

animals. This is quite exciting. We

catch the animals at night. This is

0:20:080:20:12

a tried and tested method. No harm

will come to these creatures by

0:20:120:20:15

having the collars fitted. They look

a bit bulky. I can assure you they

0:20:150:20:22

are not intrusive. We've called one

of them David Bowie. In fact this is

0:20:220:20:27

David Bowie going in there at the

moment and making his exit, having

0:20:270:20:31

come around from the sedative. The

other couple we have named Kate Bush

0:20:310:20:36

and Mark Almond. There is David, off

into the night, transmitting away.

0:20:360:20:41

So, have we seen our badgers since?

Well, let's take a look. This is

0:20:410:20:48

where David Bowie was released. Now,

we have got badgers there. We have

0:20:480:20:52

spotted them. You can see that is

not David Bowie because it hasn't

0:20:520:20:57

got the collar. However, take a

close look through the trees and

0:20:570:21:00

there you go, you can see the

collar. So that is definitely the

0:21:000:21:06

badger, David Bowie. We are hoping

to see a closer view of him.

0:21:060:21:11

Hopefully he's not touch of a rebel,

rebel. Once he's used to the

0:21:110:21:16

cameras, he'll enjoy his fame, so

long as he's not under pressure to

0:21:160:21:20

perform!

What a cascade of pop

references.

0:21:200:21:31

references. We OK, so here they are.

Here are the badgers that we've

0:21:310:21:35

marked. We have David Bowie over

here. Then we have got Kate Bush

0:21:350:21:39

here and Mark Almond here. What is

interesting is there is about 1,000

0:21:390:21:43

metres between these two and not

much distance between Kate Bush and

0:21:430:21:47

Mark Almond. Probably not true in

real life, but for the animals here,

0:21:470:21:52

the case. Why are we doing this? The

badgers are behaving A-typically in

0:21:520:21:59

the way they use the landscape for

raging and locating their seblingts.

0:21:590:22:05

Kate Bush -- their sects. Kate Bush

and Mark Almond are closely related.

0:22:050:22:15

We have seen them doing a lot of

stuff, haven't we?

This is Mark

0:22:150:22:23

Almond, out snuffling around,

marking his territory there. He is a

0:22:230:22:28

male - he has a broad head. He is

relatively young as well. Nice

0:22:280:22:32

condition - not a lot of fighting

going on. A very handsome Mark

0:22:320:22:37

Almond. Got the dark marks around

the eyes, just like Mark's 80's make

0:22:370:22:43

up as well. At this time of the year

the badgers are out and about. It

0:22:430:22:48

has been mild. They have been doing

grooming. A lot of foraging going

0:22:480:22:52

on. No need for them to stay Down

Under ground because it has not been

0:22:520:22:59

that harsh, the weather. They say

hello. Then they wave goodbye. That

0:22:590:23:04

is pretty much the story of the

1980s.

We have live cameras on those

0:23:040:23:10

badgers as well. We don't have

anything on them right now but if we

0:23:100:23:15

see any badgers hopefully we will

see Kate Bush. I think she may be

0:23:150:23:18

running up that hill. Hopefully

she'll be back. It's not going to

0:23:180:23:23

stop, is it - all week! Now to

Martin, if he was an '80s icon, who

0:23:230:23:27

do you think he'd be?

Status quo.

That sage hair. I was thinking Bon

0:23:270:23:37

Jovi.

Less of the grey shagy hair.

Here I am. I am in the Sherborne

0:23:370:23:45

brok.

0:23:450:23:51

brok. The river is trickling past

me. A perfect winter's night. Back

0:23:510:23:57

in Autumnwatch we delved into the

magical underwater world of the

0:23:570:24:01

brown trout and I fulfilled a

childhood dream.

0:24:010:24:08

We weren't sure whether we could

find the trout, so I was dressed up

0:24:080:24:13

in these elegant clothes to try and

find them. I wanted to enter the

0:24:130:24:19

actual water. There they are. I got

very, very over excited.

0:24:190:24:29

There were two! There were not just

a couple of trout, these are brown

0:24:290:24:35

trout. I began to speculate, in

Winterwatch, where would they start

0:24:350:24:39

to lay their eggs? I thought I had

found the per text spot. -- perfect

0:24:390:24:47

spot. It turned out I was wrong. Not

completely wrong because I am a

0:24:470:24:54

kilometre downstream from where I

thought they would lay their eggs. I

0:24:540:24:57

want to show you something curious.

If you look down in the water here,

0:24:570:25:04

the substrate is... Oh, that is my

sweater gone! It's really dark.

0:25:040:25:09

These pebbles are really, really

dark there. The gravel, but now, if

0:25:090:25:14

I move out, you can see these

patches, much, much lighter.

0:25:140:25:17

Like that. I don't know if you can

see that. You probably can. Look, it

0:25:170:25:22

is steaming now. It is get oh cold.

During the day those patches of

0:25:220:25:28

light and dark are really, really

obvious. So what is doing this? Can

0:25:280:25:32

you see... This is where I am

standing now, during the day, look

0:25:320:25:36

you can see that very, very clear

light coloured area. And there are

0:25:360:25:43

also, now look closely, can you see

the mid-tofl -- in the middle of the

0:25:430:25:50

frame, there are some trout. One is

doing something curious. What is

0:25:500:25:54

happening here and it is probably

finished now, the females come to

0:25:540:25:58

these areas and they clean the

gravel. They get rid of all the

0:25:580:26:03

silt. They use their tail, bash it

up and down and they clear all of

0:26:030:26:07

this. Not one trout has done that.

Quite a few have done that. They

0:26:070:26:13

call it a redd. It is an ancient

word meaning to tidy up or to clean.

0:26:130:26:20

Once the female has done that and

tidied up and cleaned it all, then

0:26:200:26:24

the next stage of the process of

reproduction takes place, the males

0:26:240:26:29

arrive. Here is the female, with a

male. You can see what she's doing,

0:26:290:26:35

seeing how she is cleaning that silt

out of the gravel. The male has a

0:26:350:26:42

difficult job. He has to encourage

the female to spawn. He does that by

0:26:420:26:47

tapping her flank with his nose. And

he will come around to the other

0:26:470:26:51

side in a moment and just gently tap

again. Here he comes. Just tapping

0:26:510:26:58

her lateral line, trying to

encourage here to spawn. Once she

0:26:580:27:02

does, he will then, he'll then

fertilise the eggs and she will

0:27:020:27:06

cover them up with gravel. He's not

the only one there. Now the males,

0:27:060:27:13

this is subtle behaviour, he has to

drive the other male off. He does

0:27:130:27:20

that by erecting his fin. He does

that by looking threatening. They

0:27:200:27:24

actually have a bite at each other.

She's carrying on, getting that redd

0:27:240:27:30

ready for the eggs to be laid in

there. The male, they sort of

0:27:300:27:35

parallel walk, like we have seen red

dear. What a waste of time for those

0:27:350:27:39

lads, because there was a big, big

male trout waiting in the wings and

0:27:390:27:44

he's come in. So the male has to be

with the female on the redd all the

0:27:440:27:50

time because the minute she lays the

eggs, he has to try and fertilise

0:27:500:27:54

them. What do they look like? They

are beautiful. They look like little

0:27:540:28:01

orange jewels there. Imagine if she

laid those eggs directly into the

0:28:010:28:06

water here, they are so small, they

would be washed away instain

0:28:060:28:09

tapously. So, all this -- instantly.

So all this business of cleaning the

0:28:090:28:16

gravel, let me put water in this,

this is what is going on underwater.

0:28:160:28:20

Here are the eggs, they are trapped

now in the gravel. The female trout

0:28:200:28:30

has pushed over the top of there. It

is nice and clean, so the water can

0:28:300:28:37

travel through, oxygenating the eggs

as they develop. That is the

0:28:370:28:40

process. Let's see what happens once

she's laid the eggs. Here they are.

0:28:400:28:45

You can see the little fish inside,

just see the eyes. Here it is

0:28:450:28:50

starting to... Can you sea the heart

beating away? There is a large yolk

0:28:500:28:56

sack. The tiny trout will live off

that sack to begin with it. It is

0:28:560:29:02

getting bigger now. Now it has to

start hunting for food. There it is.

0:29:020:29:07

They will snap away at any little

thing that passes by. Trout here,

0:29:070:29:12

these are very small, they may lay

100, up to 300 eggs down there. It

0:29:120:29:17

will take a few months for them to

develop, quite slowly, dependant on

0:29:170:29:22

the temperature of the water. When

they do hatch out there'll be

0:29:220:29:28

crustaceans for them to eat. If you

go down to your river and see the

0:29:280:29:32

strange pattern of the dark and

light you will know what made it.

0:29:320:29:36

The process of the eggs hatching out

is very weather-dependant. What will

0:29:360:29:40

happen to the weather? Well, I know

a man who knows. It is time to go

0:29:400:29:45

over to find out.

0:29:450:29:47

Some rain this week. River levels

holding up. We have been mild to

0:29:500:29:56

cold a lot this winter and seen

unusual things. This adder out and

0:29:560:30:04

about in Devon. The sun is getting

stronger at this time of year. I

0:30:040:30:08

have seen bats flying at dusk. Mild

to cold and back again.

0:30:080:30:15

The forest is home to red squirrels.

0:30:180:30:20

It has been occasionally storming,

nothing too bad for the birds but if

0:30:200:30:26

you are doing some garden bird

watching you know it has been mild.

0:30:260:30:30

Turning colder this week, weather

systems working south, cold air

0:30:300:30:35

behind, some wintry showers. It's

already turning colder in Sherborne,

0:30:350:30:40

a frost is setting in and after a

mild start to the week, the rest of

0:30:400:30:44

the week will be single figures. A

lot of winter is left yet. The great

0:30:440:30:49

news is that there is a lot of

Winterwatch left yet too!

0:30:490:30:53

news is that there is a lot of

Winterwatch left yet too!

It's going

0:30:530:30:54

to be chilly, the woolly hats coming

out. At the weekend, loads of you

0:30:540:31:02

get involved in the bird watch. Some

of you may have done it today. Lots

0:31:020:31:06

of pictures on Twitter. That is

molar. I like how she has her

0:31:060:31:12

bird-watching books out -- that is

Lola. This is Batman looking for

0:31:120:31:19

Robin. He's dressed up and he his

binoculars. The old folk are doing

0:31:190:31:24

it as well, the Abbey Fields said

Alden 's care home have been

0:31:240:31:29

counting too. Well done to the body.

This is possibly one of the greatest

0:31:290:31:35

citizen science projects running in

the world, it has been running for a

0:31:350:31:38

long time, enormous numbers of

people take part, over half a

0:31:380:31:42

million last year so we can generate

real data. We have no data from this

0:31:420:31:47

year yet but we have a graft, the

last ten years. A couple of species

0:31:470:31:51

we can look at, it shows how many

birds are appearing in the garden

0:31:510:31:57

over the hour. Look at greenfinch,

declining rapidly over the last ten

0:31:570:32:02

years and the wood pigeon is

increasing. What's happening?

0:32:020:32:09

Woodpigeon, up 51.6%. Maybe because

they aren't migrating to the

0:32:090:32:12

continent and they are coming into

our gardens? Greenfinches are

0:32:120:32:15

declining because they are infected

with a disease in gardens which has

0:32:150:32:23

been knocking them out quite

seriously.

The RSPB will be putting

0:32:230:32:25

the results together and we will

know them in due course. When you

0:32:250:32:30

were doing your bit garden bird

watch, how many of you saw something

0:32:300:32:33

like this? This was sent in by the

wildlife gadget man. You can see a

0:32:330:32:40

rat coming out of the hedges to the

garden bird feeder. Keep watching

0:32:400:32:47

its eye in the corner. Keep

watching, watch closely, and look at

0:32:470:32:54

that! A tawny owl comes in. Did it

get the

0:32:540:32:58

that! A tawny owl comes in. Did it

get the rat? Let's have a look

0:32:580:33:00

again. It's in the bush.

0:33:000:33:03

get the rat? Let's have a look

again. It's in the bush. It comes

0:33:030:33:05

out... I don't think so, Chris,

because it would have been

0:33:050:33:09

struggling a bit more.

That is a

great prey item for a tawny owl, the

0:33:090:33:17

rat would have been 100 grams at

least. They are formidable nocturnal

0:33:170:33:22

predators, taking advantage of that

rat. We've just Mr seeing a badger

0:33:220:33:29

on the thermal cameras but we can

look at it now. It isn't one of our

0:33:290:33:37

collared individuals.

It is looking

gorgeous.

It is a thermal image,

0:33:370:33:42

what is white is warmer and what is

darker is cooler. We can see the

0:33:420:33:47

animals unobtrusively, there is no

infrared light. A bit of grooming.

0:33:470:33:53

With the wet weather, it is a

bonanza for worms, I think it's

0:33:530:33:56

getting them.

Please get in touch, we love it when

0:34:310:34:37

you do. Let's go back to Islay where

Gillian is looking for otters that

0:34:370:34:42

are hanging around a whiskey

distillery, the perfect place to do

0:34:420:34:46

some wildlife watching, if you ask

me!

Welcome back to Islay. Yes,

0:34:460:34:51

we've come to a whiskey distillery

because we've been following four

0:34:510:34:57

otters to use this coastline

regularly. We have a live camera

0:34:570:35:01

which we want to go to straightaway

and see if we have any action. There

0:35:010:35:04

you

0:35:040:35:09

you can see, there's no action but

we've seen signs of otters

0:35:090:35:12

everywhere. Have a look at this. If

I live this up here... -- lift this

0:35:120:35:20

up. This is a couch, which is like a

daytime hideaway. If you look here,

0:35:200:35:28

the otter that's been using it has

been busy. Fragments of cell, bits

0:35:280:35:32

of crab shell here. This is

unmistakable -- fragments of shell.

0:35:320:35:38

Whoever is using this is having a

jolly good time. Winter is a really

0:35:380:35:45

difficult time for all animals,

otters are no exception and the

0:35:450:35:49

obvious reason, one of the main

thing is, they need to stay warm.

0:35:490:35:54

They've got to eat 15% of their body

weight each day to meet energy

0:35:540:35:58

requirements. That's not easy when

the water is hovering around 8-10d.

0:35:580:36:05

You don't have to take my word for

it, look at these pictures. They are

0:36:050:36:11

the mountain is here. Imagine how

cold the water is. That is our dog

0:36:110:36:22

otter, out on a foraging trip. As he

goes down he isn't chasing fish in

0:36:220:36:26

the water column, he's looking for

sleeping Fish, nocturnal fish that

0:36:260:36:31

are hiding away in cracks and

crevices. Each dive is 15-20

0:36:310:36:37

seconds, he comes back up for air

and then he dives back down again.

0:36:370:36:42

He knows the territory well, he

knows where he's had success and

0:36:420:36:46

caught fish before. This time when

he comes up he's got something.

0:36:460:36:50

caught fish before. This time when

he comes up he's got something. But

0:36:500:36:53

that's a tiny morsel, he'll have to

do that again and again through the

0:36:530:36:56

day. After 20 minutes in the water,

his body temperature will drop by

0:36:560:37:02

about 1 degrees and eventually he's

going

0:37:020:37:04

about 1 degrees and eventually he's

going to get out.

0:37:040:37:06

about 1 degrees and eventually he's

going to get out. You be seen your

0:37:060:37:09

dogs doing this, having a good shake

and the next thing they do is roll

0:37:090:37:14

around. He looks for a lovely

0:37:140:37:15

and the next thing they do is roll

around. He looks for a lovely patch

0:37:150:37:15

of seaweed and that looks like it

feels good! But the reality is that

0:37:150:37:24

grooming isn't just about feeling

good, it's absolutely vital to their

0:37:240:37:28

survival. Their fur coats are like

their survival suits and may need

0:37:280:37:33

maintaining. We've got this old pelt

here which I thought would be nice

0:37:330:37:38

to show you. It is absolutely smooth

on the outside, it has long hair,

0:37:380:37:43

but when you peel the layer back,

you can see this thick fluffy under

0:37:430:37:49

fur. It is so thick I can't actually

see the skin underneath it. There

0:37:490:37:55

are 50,000 hairs in a square

centimetre, about the size of mind

0:37:550:37:59

and nail. That acts to trap the warm

air by the otter's skin. To give you

0:37:590:38:07

a sense of how dense that is, a dog

has 9000 squares per centimetre. So

0:38:070:38:17

it's an incredible adaptation. The

adults are great hunters but what

0:38:170:38:20

about the juveniles? Let's have a

look.

0:38:200:38:24

about the juveniles? Let's have a

look. This is our juvenile here.

0:38:240:38:28

They can swim from quite young, but

they need about two years to become

0:38:280:38:34

expert divers. While they are

learning how to dive really well,

0:38:340:38:40

they have to go after the easier

prey, but less nutritious. That

0:38:400:38:43

isn't a fish, he has caught a crab.

You can imagine that crabs are not

0:38:430:38:50

easy to eat out on the water so the

juveniles have two waste a lot of

0:38:500:38:56

energy going onto dry land to

process the crab and eat it. When

0:38:560:39:02

he's done that he's going to go back

out again and find more. These

0:39:020:39:07

he's done that he's going to go back

out again and find more. These

0:39:070:39:08

juveniles are on an energetic knife

edge and this really steep learning

0:39:080:39:12

curve shows up in the statistics.

Less than half of all otters make it

0:39:120:39:17

to four years old and this first

year of winter, the first winter is

0:39:170:39:22

the most challenging time. But if

this couch over here and all these

0:39:220:39:27

scraps of shrapnel are anything to

go by, then we feel that these

0:39:270:39:33

otters here, the juveniles should do

well this winter. It's been so

0:39:330:39:39

lovely getting to know these

animals. Tomorrow we're going to be

0:39:390:39:43

heading to the south of the island,

where it's possibly the best place

0:39:430:39:47

in the country, all of Britain, to

see golden eagles. It's also where a

0:39:470:39:53

very passionate scientist has been

championing a little-known bird.

0:39:530:39:59

I am Jamie and I study a very niche

finch living in hard to reach places

0:40:050:40:10

called the Twite. They are a little

brown finch. You generally hear them

0:40:100:40:23

first and you wouldn't recognise

where the call is coming from. In

0:40:230:40:27

winter they move to the coast.

Currently they have a nature reserve

0:40:270:40:36

on Islay where we are looking at the

population which was planted by the

0:40:360:40:40

RSPB.

This large winter flock offers

Jamie the opportunity to study their

0:40:400:40:47

movements and survival through a

collaring programme.

To catch Twite

0:40:470:40:54

we need to use a net which fires

over the net as they fly in to feed.

0:40:540:41:04

Doctson, go! It means we catch the

entire flock at once and there is a

0:41:040:41:11

team to process these birds and

extract them -- Doctson, go!

0:41:110:41:16

We colour in the Twite as

individuals. With collaring is we

0:41:180:41:25

don't have two capture the birds

again, anyone can read them and send

0:41:250:41:29

us the data, it is a citizen science

project. We rely on bird watchers to

0:41:290:41:38

report them to us. We've had over

130 people reporting Twite in the

0:41:380:41:46

time we've had the project so far.

Twite and Lynette interestingly our

0:41:460:41:53

two of the only species that feed on

these seeds which have no in

0:41:530:41:57

vertebrates diet whatsoever which

mean that Twite rely on meadows.

0:41:570:42:04

Farming practices have meant that

the meadows are less viable and the

0:42:040:42:09

population has subsequently

declined. In the last ten years in

0:42:090:42:14

England we've seen them decline as

much as 50%. We know that the

0:42:140:42:18

decline is continuing despite

conservation.

0:42:180:42:24

conservation. The Welsh and Northern

Irish populations are very small

0:42:240:42:30

comedy in this one, probably less

than 150 pairs now. The Scottish

0:42:300:42:35

ones have several thousand pairs

although they are hard to monitor.

0:42:350:42:38

They are very remote readers and

easy to miss in the expansive

0:42:380:42:43

moorland -- remote breeders. They

are declining in places where we are

0:42:430:42:51

looking and they may disappear

without any of us noticing.

0:42:510:43:02

Research historically has favoured

charismatic species, they draw the

0:43:090:43:16

funding and time, they engage

collective imagination. Birds that

0:43:160:43:19

live a long way away in wet, windy

moorland, no one sees, they deserve

0:43:190:43:24

the same amount of protection. You

just get colder doing it!

0:43:240:43:36

It's so true, research favours the

charismatic but it's great to see

0:43:380:43:41

the little brown birds getting some

support.

Got to champion the

0:43:410:43:47

underdog. Let's go to the thermal

camera where we've got one of our

0:43:470:43:52

badgers, in fact two badgers. This

is as what we are calling the

0:43:520:43:56

century set meaning the animal you

see on the side of your screen is

0:43:560:44:03

Mark, after Mark Almond. They are

very busy at the sets at this time

0:44:030:44:11

of year, there's a lot of digging

going on, over the next month or so

0:44:110:44:15

the females are going to give birth

so they are cleaning out the set and

0:44:150:44:19

bringing in some bedding and you can

see some on the surface. This is

0:44:190:44:23

life but a few moments ago we saw

some badger behaviour. Here is Mark

0:44:230:44:29

doing some mutual grooming with

another badger in the set there.

0:44:290:44:37

Tickling its Soft Cells! Galan how

many of these are we going to get

0:44:370:44:40

in?

0:44:400:44:45

We've tried so hard to get them and

finally we have succeeded. We like

0:44:450:44:49

an experiment and we are lucky at

Sherborne because there are lots of

0:44:490:44:53

farmland birds, things like these.

We have Lynette 's -- linnets,

0:44:530:45:03

yellow hammers, skylarks. These

birds have been in dramatic decline

0:45:030:45:08

in recent years but there is active

management going on at Sherborne

0:45:080:45:12

which attracts them and makes a

habitat for them. At this time of

0:45:120:45:17

year they flock together which is

why we decided to do an experiment.

0:45:170:45:21

Many farmland bird species are in

trouble, loss of habitat, the

0:45:210:45:25

intensification of agriculture are

knocking them back but many farmers

0:45:250:45:29

and sign up to Stuart said --

stewardship schemes: putting down

0:45:290:45:34

seeds and some farmers put the seeds

out to make sure that the

0:45:340:45:40

populations prosper. We have a

mixture here, typical of the kind of

0:45:400:45:44

thing that goes out on the field for

those birds. But which seeds are

0:45:440:45:49

eaten by which species? We've got a

simple experiment, six trainees and

0:45:490:45:54

into each one of them we have poured

a different kind of seed. -- six

0:45:540:45:58

trainees. Days is whether flocks

have been coming to feed. We have

0:45:580:46:05

rape seed...

0:46:050:46:07

We will continue to monitor these

over the next few days, recording

0:46:110:46:15

which species appear so, we can see

which of these seized seeds are

0:46:150:46:24

beneficial and which are left. My

prediction is they will go for the

0:46:240:46:29

rape seed. If we get any garden

birds in, the greenfinches they will

0:46:290:46:36

go for them. What about you?

I think

maybe the wheat. No, sunflower. I

0:46:360:46:44

think you are right right. A lot

have visited the feeders. We will

0:46:440:46:51

look at that tomorrow. We have had

quite a bit of a success with that

0:46:510:46:55

already.

Those are not the only

species we see flocking together at

0:46:550:47:00

this time of year. If you were out

and about in the late afternoon you

0:47:000:47:06

might see corvids forming very large

and impressive flocks.

They are very

0:47:060:47:10

intelligent. Which is the most

intelligent? We decided to take the

0:47:100:47:15

two largest corvids and put them to

a test. It was an epic battle. It

0:47:150:47:22

was a feathery fight for supremacy.

It was the clash of the corvids, or

0:47:220:47:27

should that be... Game of crows? !

0:47:270:47:34

The carrion crow... It is the

ultimate battle of the brainy birds.

0:47:500:47:58

But which one will be crowned king

of the corvids?

0:47:580:48:05

There can only be one winner.

There can only be one winner the

0:48:050:48:13

Game of Crows! This is Bran the

Raven. He weighs 7.1 and he has a

0:48:130:48:25

wingspan of 1.35 metres. His

favourite toy is a stone. But don't

0:48:250:48:28

let that fool you because this is

the master mind of the bird world.

0:48:280:48:37

And that's why I'm I'm with him.

That sounds like a challenge. Let me

0:48:370:48:44

introduce you to Zim. She a carrion

crow. Although he's half the size,

0:48:440:48:49

crows are considered fearless, one

of our most clever birds. At 22

0:48:490:48:54

years of age, he's been through the

wars, but with age comes experience.

0:48:540:48:59

Which is why I'm championing Zim.

When you play the Game of crows, you

0:48:590:49:06

win or you die.

Not you, mate!

The raven and crow

0:49:060:49:13

will be set four games. Each

designed to test their

0:49:130:49:19

problem-solving abilities.

0:49:190:49:24

problem-solving abilities.

They have

been familiar rised with the props,

0:49:250:49:30

but not taught or trained to master

them.

Game one - the iron thrown. --

0:49:300:49:38

the iron throne. This will test

their ability for survival in the

0:49:380:49:42

wild.

The birds must out-compete

each other by removing the swords as

0:49:420:49:46

quickly as possible to get a food

reward.

0:49:460:49:51

And before the two-minute hour glass

runs out.

0:49:510:49:56

First up, Bran, the raven. About the

size of a buzzard ravens are the

0:49:560:50:03

largest member of the crow family.

Let it begin.

0:50:030:50:08

The sands of time are ticking.

0:50:080:50:10

So first up the raven. Straight in,

Martin. Look at that.

The accuracy

0:50:150:50:21

of the bill too.

You might think it

is big and clumpy.

Come on, do your

0:50:210:50:27

stuff.

In fact, the dexterity is

remarkable. Down goes the bait.

Oh,

0:50:270:50:37

he's got it. Looking for more. Well

done!

And the sands of time say 50%.

0:50:370:50:42

50%. That is a very good effort. I

am impressed.

Most people think the

0:50:420:50:47

beak of the raven is there to bash

out the brains and peck out the

0:50:470:50:51

eyes. What we have seen is a

demonstration of the fact it has

0:50:510:50:55

remarkable dexterity. Not only did

it remove the swords very quickly,

0:50:550:51:01

it did it neatly.

I think the crow

can do better.

Let's reset the iron

0:51:010:51:05

throne.

Bring on the ancient and

slightly grumpy crow.

0:51:050:51:12

Well done!

He's nippy! Look at this!

Good boy! He 's got it. Check the

0:51:120:51:26

sands of time. Oh! Only about one

third through there, mate.

Well

0:51:260:51:32

done. He's old... But he's bright.

1-0 to the crow.

0:51:320:51:41

Game two - the guillotine.

0:51:410:51:48

Game two - the guillotine. This

tests corvid curiosity. This is a

0:51:500:51:53

game to access food sources.

Here

they must act

0:51:530:52:06

they must act as executioneer.

Take two. About four grains.

Four

0:52:080:52:13

grains!

That was really impressive because

0:52:130:52:17

even if it didn't work he went for

it again.

0:52:170:52:23

it again.

They are both liking and

fearing new things. They need to get

0:52:230:52:28

the balance right. He came straight

in and the first thing he thought is

0:52:280:52:35

there is a piece of string,ly pull

it, something nice might happen.

I

0:52:350:52:39

am worried now, the crow may have a

little job on here. Come on... Good

0:52:390:52:47

boy. Pull the string, pull the

string, come on...

Oh, he's having a

0:52:470:52:53

look around! Hammering the blade.

He's got it.

Hold on!

Cheated.

0:52:530:53:00

Excellent. He does haven't to pull

the string. He's gone straight in

0:53:000:53:05

there and bashed away and got the

food. Impressive.

You say that, but

0:53:050:53:10

he's behaving like the hound, it's

all brute force with little brains.

0:53:100:53:18

It is effective.

It was mission

accomplished, but not as fast. I

0:53:180:53:23

think 26 grains of sand. So the

raven takes it.

Because he's so old

0:53:230:53:28

you must allow him a certain amount

of...

No, mate, not on Game of

0:53:280:53:33

crows. No mercy. Let's draw swords

for the next round.

1-1... All to

0:53:330:53:40

play for!

0:53:400:53:42

It is nail-biting stuff! You two

looked quite dashing in your

0:53:460:53:53

medieval outfits. You should wear

them more often. Who will be the

0:53:530:53:56

winning bird? Will the crow take the

crown or will the raven reign? Cast

0:53:560:54:04

your votes online, on our website.

We will reveal what you thought

0:54:040:54:09

tomorrow before part two of Game of

Crows. There can only be one winner.

0:54:090:54:14

Which bird will it be? All exciting

stuff. I am on the edge of my seat.

0:54:140:54:19

It is very difficult to tell the

difference between members of the

0:54:190:54:22

crow family. There are eight in

total. And the tricky ones are the

0:54:220:54:28

black-bodied one, the raven, carrion

crow and the jackdaw and rock. There

0:54:280:54:33

is the black bodied chuff. My

favourite birds. You only see those

0:54:330:54:37

on the coast. They are rare.

Beautiful red bill and legs. There

0:54:370:54:42

are the easy ones, the magpie, the

ja and the hooded crow. So the black

0:54:420:54:48

bodied one. Here is our handy guide

to telling the difference. First of

0:54:480:54:53

all, size.

One of the best props

ever devised. A pop-up raven. A

0:54:530:55:01

wingspan of 1.3 metres and a

distance between beak and tail about

0:55:010:55:07

65 centimetres, these birds weigh

about 1.3kgs. They are huge birds,

0:55:070:55:12

ass you can see.

That is -- as you

can see. That is massive. Are you

0:55:120:55:19

sure that is the size?

This is the

size.

Right, here we go, and this is

0:55:190:55:27

the carrion crow, much, much smaller

than the raven. I have a cheat on

0:55:270:55:30

the back here. The wingspan is 98kms

and the weight is about -- 98

0:55:300:55:38

centimetres and the weight.

The Rook is lighter. A 90 centimetre

0:55:380:55:47

wingspan. 310 grams.

0:55:470:55:53

wingspan. 310 grams.

She's reading

it off the back. This is the Jack

0:55:530:56:00

daw. It's 75% less than your rather

massive bird over there. It is

0:56:000:56:07

enormous.

When they are side by side

like this, it is easy to see the

0:56:070:56:11

difference.

That is if you see them

in the sky. What about if you come

0:56:110:56:15

face-to-face with these animals on

the ground. Look at them there. The

0:56:150:56:19

raven, a huge head. Massive bill,

black eyes and the fortitude of that

0:56:190:56:24

bill you should look at and its

fluffy beard.

Then there is a crow

0:56:240:56:29

there. A very egapt corvid. -- a

very elegant corvid. Smaller than

0:56:290:56:37

the raven. What about the rook?

0:56:370:56:45

the raven. What about the rook? That

is like the Owen Wilson.

0:56:460:56:57

The Jackdaw is very attractive. It

has a nice nose. I would say it is

0:56:570:57:05

more like George Clooney. That very

distinctly has those lovely blue,

0:57:050:57:12

sort of slaty eyes.

Have you got

Jackdaws dropping sticks down your

0:57:120:57:20

chim anies?

0:57:200:57:25

chim anies? -- down your chimneys.

That was your easy guide to corvids.

0:57:260:57:32

Now we are running out of time. Now

a look at the kingfisher. It is

0:57:320:57:37

displaying extraordinary behaviour.

Look at how it is keeping its head

0:57:370:57:41

completely still. This

0:57:410:57:47

completely still. This such a

re-election.

We are back tomorrow.

0:57:500:57:54

It is 8pm tomorrow. Not 9pm. It is

8pm. Let's see what we have coming

0:57:540:57:58

up. We will be with Gillian in

Islay. She will explore that island.

0:57:580:58:08

It is unusual, a couple of

vegetarians go out to the butcher's

0:58:080:58:11

shop. That is what we did in search

of a great bird.

I will have a

0:58:110:58:23

mesmerising experience with the Red

Kites. We would like to apologise to

0:58:230:58:29

Nick Miller for calling him my

father-in-law. See you tomorrow.

0:58:290:58:36

8pm, not 9pm.

See you then.
