Hello. I'm Chris Packham, and this is Nature's Top 40.

0:00:020:00:05

From flowers to butterflies, from reptiles to mammals,

0:00:050:00:10

we set out to find the number one wildlife show in the land.

0:00:100:00:13

It's simple really, it's the UK's top 40 wildlife spectacles,

0:00:220:00:27

ranked in order of total magic.

0:00:270:00:30

Meet the head bangers - it's the battling billys of Wales.

0:00:310:00:37

There, there. You'll see him, you'll see him!

0:00:370:00:41

And as ranked by our panel of wildlife experts,

0:00:410:00:44

the otter enters our charts.

0:00:440:00:46

I've never known anything like it. My heart started to go...!

0:00:460:00:50

We've taken suggestions from the public,

0:00:500:00:53

and thrown in a few of our own.

0:00:530:00:54

Every idea has been scored for beauty, scale, excitement

0:00:540:01:00

and rarity in our search for the UK's number one wildlife show.

0:01:000:01:06

Today, our charge up the charts continues.

0:01:060:01:10

You'll recognise these rather boisterous animals as goats -

0:01:120:01:15

one of nature's lawnmowers.

0:01:150:01:17

They've got a voracious appetite for everything, including the paper bag.

0:01:170:01:23

Now, they're also, obviously, farm animals,

0:01:230:01:25

and sometimes they make great pets,

0:01:250:01:27

but in the wild, when they put these horns to their proper use,

0:01:270:01:31

they can provide one of the greatest fighting spectacles that you can see

0:01:310:01:36

in the wilds of the UK, outside of this encounter!

0:01:360:01:39

At number 32, rutting goats.

0:01:390:01:42

It's not quite the badlands,

0:01:460:01:48

but there's trouble brewing in these hills.

0:01:480:01:52

Big trouble.

0:01:520:01:54

I'm on the trail of rutting goats, and this is

0:01:540:01:57

one of the best places to see them, the Nant Gwynant Valley in Snowdonia.

0:01:570:02:02

How impressive is that?

0:02:020:02:04

They're not everyone's cup of tea,

0:02:060:02:07

but here's why I think these animals deserve their place in our Top 40.

0:02:070:02:12

You can forget rutting deer, all that namby-pamby pushing and shoving.

0:02:120:02:17

That's what I call having a proper head-to-head!

0:02:170:02:21

At least now I know the goats are here.

0:02:280:02:30

The best part of 30 up there, I think.

0:02:300:02:32

There are billy goats,

0:02:320:02:33

there are nannys and kids.

0:02:330:02:35

The trouble is, the goats are up there and I'm down here,

0:02:350:02:38

so there's quite a bit of walking to do yet.

0:02:380:02:40

GOAT BLEATS

0:02:400:02:43

Now, tracking goats isn't easy,

0:02:430:02:44

so I've called in an old friend, Howell Roberts,

0:02:440:02:47

a man who spends most of his spare time up in these mountains.

0:02:470:02:51

Sometimes the goats will come down into the valleys,

0:02:510:02:54

but today, they're making us work hard.

0:02:540:02:57

Oh, that's a climb!

0:02:570:02:58

But well worth it.

0:02:580:03:01

Ravens? Yes. A pair of ravens.

0:03:010:03:02

Yes, we're in their environment here now.

0:03:020:03:05

These high crags and open mountains, ideal places for them to nest.

0:03:050:03:08

And plenty of food for them up here.

0:03:080:03:10

Fantastic. I like ravens.

0:03:100:03:13

Howell, you know your goats. What are the chances of seeing them,

0:03:170:03:21

and even better, seeing the rut today?

0:03:210:03:23

There should be plenty of chances of seeing goats,

0:03:230:03:25

especially now that we're almost reaching the skyline here.

0:03:250:03:28

You will be able to look down and across the valleys.

0:03:280:03:31

The chance of seeing the rut,

0:03:310:03:33

well, that's a bit more of luck involved in that.

0:03:330:03:36

But if you keep on looking, you never know what you'll see.

0:03:360:03:39

The rut happens every September and October,

0:03:390:03:42

when the billys that have been living separately in the hills

0:03:420:03:45

look for groups of nannys who are now in season.

0:03:450:03:49

This is just the one herd here, Howell, is it?

0:03:490:03:51

Just the one herd on this part of the mountain,

0:03:510:03:54

but if you went on the other side,

0:03:540:03:56

you'd see more goats there, as well.

0:03:560:03:58

So is it just the one billy leading this herd?

0:03:580:04:01

Billys don't tend to lead herds.

0:04:010:04:03

It's an adult nanny that leads the herd.

0:04:030:04:06

The billy just hangs on afterwards, as part of the group.

0:04:060:04:10

If you have a look, you'll see that there are two billys,

0:04:100:04:13

but there are a large number of nannys,

0:04:130:04:15

and a number of youngsters there, as well, last year's young.

0:04:150:04:19

So you've got a good cross-section.

0:04:190:04:21

And this is just one dominant billy we've got here,

0:04:210:04:24

and he's the one with the huge, huge horns.

0:04:240:04:26

Very distinctive horns, almost like handlebars on a bike.

0:04:260:04:29

Very, very large horns.

0:04:290:04:31

Have a look carefully at the horns,

0:04:310:04:33

you can see the growth rings on them, in other words,

0:04:330:04:36

as to how, each year, there's a little bit of growth on the horn,

0:04:360:04:40

and you can age an animal from the horns.

0:04:400:04:42

I think that billy is about seven or eight years old.

0:04:420:04:45

What signifies the beginning of a rut, then?

0:04:450:04:48

I think you've noticed it already today, it's the smell.

0:04:480:04:51

You can smell the adult males, very strongly,

0:04:510:04:54

very strong body odour that they've got,

0:04:540:04:57

probably from the urine that they pass out.

0:04:570:05:00

But it's very, very distinctive.

0:05:000:05:02

I could actually smell the goats before we saw them, even,

0:05:020:05:07

it's like strong, strong goat's cheese.

0:05:070:05:10

Yes. That's usually the first indication.

0:05:100:05:13

At other times of the year,

0:05:130:05:14

you can come across them accidentally,

0:05:140:05:16

and you're unaware that you're gonna come across a goat.

0:05:160:05:19

But in this time of the year, you've got plenty of warning.

0:05:190:05:23

When males clash, it's not about inflicting damage, but dominance.

0:05:230:05:28

It's a constant round of battles as young billys,

0:05:310:05:33

driven by the desire to mate, come into conflict

0:05:330:05:36

with established males who will defend their nannys with gusto.

0:05:360:05:41

Ouch!

0:05:410:05:44

Why now, then, Howell?

0:05:440:05:45

Well, it's this time of the year they start breeding.

0:05:450:05:49

They are probably in their best condition now, after a good summer,

0:05:490:05:53

and then they will be kidding in the early spring.

0:05:530:05:55

In other words, in February or March.

0:05:550:05:58

I must confess, I like goats, I like the fact that we've got goats here,

0:05:580:06:03

but I know that some naturalists do get a little bit touchy,

0:06:030:06:06

a little bit sniffy with the fact that they're not true wild animals.

0:06:060:06:10

Well, they're the nearest you can get in Snowdonia

0:06:100:06:13

or even in Britain, I think, to wild animals.

0:06:130:06:16

Yes, they're domesticated animals, domesticated about 3,000 years ago,

0:06:160:06:20

Neolithic times, that have gone wild,

0:06:200:06:22

and all these animals are descendants of those,

0:06:220:06:25

perhaps with some more recent introduced blood

0:06:250:06:28

from farms or smallholdings

0:06:280:06:30

where animals have escaped,

0:06:300:06:32

or perhaps the practice of keeping goats

0:06:320:06:34

is not so popular now as it was.

0:06:340:06:36

Look at how close we are today,

0:06:360:06:38

look at the way they're not really moving away from us,

0:06:380:06:41

they've got quite used to us by now.

0:06:410:06:43

If you went closer and made noise, perhaps they would move.

0:06:430:06:46

But it really is quite a thrill to see them here.

0:06:460:06:49

Today, however, our billys were playing it cool

0:06:490:06:52

on a rather hot autumn day.

0:06:520:06:55

I tell you what I have got is some footage here

0:06:550:06:58

that a member of the public took,

0:06:580:07:00

pretty high up the mountain, actually.

0:07:000:07:02

-Two billys here, here we are...

-Yeah.

0:07:020:07:04

-And that's what we hoped to see today, wasn't it?

-Did you hear that?

0:07:040:07:08

-Yeah.

-That bang, it really is full-on, 100mph stuff,

0:07:080:07:14

-they go up on their hind legs and they crash...

-And again!

0:07:140:07:17

No. No head-banging that time,

0:07:170:07:19

but at least he reared up on his hind legs,

0:07:190:07:21

and he's obviously got the message.

0:07:210:07:23

Bang! That was a bit painful, wasn't it?

0:07:240:07:27

You can hear that clash of horns, even from, I would imagine,

0:07:270:07:30

on a still day like this, from half a mile away.

0:07:300:07:33

You certainly would,

0:07:330:07:35

you'd know that there was some activity going on up there,

0:07:350:07:38

and quite aggressive activity, as well.

0:07:380:07:40

There you go, I told you it was good.

0:07:410:07:43

Fantastic scenery and dynamic animals,

0:07:430:07:46

what an explosive combination!

0:07:460:07:48

Now for a creature that's a surefire sign of summer -

0:07:540:07:57

well, if you've got more than one of them, of course, that is.

0:07:570:08:00

I've got to say they're one of our greatest migrants,

0:08:000:08:03

in the springtime, they tend to arrive in dribs and drabs,

0:08:030:08:06

but when they're ganging together in the autumn, to leave,

0:08:060:08:09

they can be really spectacular.

0:08:090:08:12

At number 31, it's swarms of swallows.

0:08:120:08:15

One swallow doesn't make a summer, but does a swallow make a spectacle?

0:08:180:08:25

I'm going to show you why swallows and their close relatives

0:08:250:08:30

deserve to be in the Top 40. And what's more,

0:08:300:08:33

we're going to see two wildlife spectacles for the price of one.

0:08:330:08:36

There are dozens of types of swallow,

0:08:360:08:40

but the ones that we have are barn swallows.

0:08:400:08:43

They're part of the hirundine family of birds -

0:08:430:08:46

along with house martins and sand martins.

0:08:460:08:50

Swifts are a separate family, similar in flight, but bigger and darker.

0:08:500:08:56

Our swallows have that distinctive long forked tail.

0:08:560:09:00

The real spectacle is when they gather in huge numbers.

0:09:000:09:04

And the swallows will do that at the end of summer,

0:09:040:09:08

when they get ready to migrate back to Africa.

0:09:080:09:12

And I'm hoping that I'll go to a site

0:09:120:09:14

where they literally roost in their thousands.

0:09:140:09:17

But there is another member of this family

0:09:170:09:19

that provides a spectacle which is a little bit less time-critical.

0:09:190:09:23

These are sand martins.

0:09:270:09:30

We see huge seabird colonies,

0:09:300:09:32

but it's unusual to have a large breeding colony inland,

0:09:320:09:36

and that's what makes these birds special.

0:09:360:09:39

This is wonderful, I'm surrounded by sand martins.

0:09:410:09:46

They're all living in this cliff here.

0:09:460:09:48

It's like the avian equivalent of a high rise block of flats.

0:09:480:09:52

In North America, these birds are known as bank swallows,

0:09:570:10:00

and along this cliff, there are 300 nests, each with parents and young.

0:10:000:10:08

I'm going to get closer to them with the RSPB's Mark Thomas.

0:10:080:10:13

They're great birds, they're absolutely magnificent things.

0:10:130:10:16

One of the key things is

0:10:160:10:18

they're one of the first birds back in the spring.

0:10:180:10:21

You've spent the whole winter dreaming of migrant birds,

0:10:210:10:24

and it gets to late March,

0:10:240:10:25

and you hear this chirping, look up in the sky,

0:10:250:10:28

there's seven grams of feathers, and it's flown 3,000 miles!

0:10:280:10:31

They've got razor sharp, very, very thin claws,

0:10:330:10:36

and they begin to excavate when they arrive in late March.

0:10:360:10:39

It takes them two to three weeks,

0:10:390:10:41

but after a while, they get the burrow,

0:10:410:10:43

it goes back about this far, and there's a chamber,

0:10:430:10:46

and in the chamber is a cluster of feathers and that's the nest,

0:10:460:10:49

and it's home for the next three to four months!

0:10:490:10:53

Sometimes, birds die in the nest.

0:10:530:10:56

And when early naturalists found them,

0:10:560:10:59

they thought that hirundines hibernated.

0:10:590:11:02

But with modern tracking and ringing, we now know they migrate to Africa.

0:11:020:11:07

The females have spent the whole time in the burrows

0:11:070:11:10

incubating eggs and chicks,

0:11:100:11:11

so what they've got is they've got a very bare patch of skin here

0:11:110:11:15

to keep the chicks and eggs warm.

0:11:150:11:16

So if we blow gently on the stomach of the bird,

0:11:160:11:18

it will either be very fleshy, or it will be covered in feathers.

0:11:180:11:21

If it's feathers, it's the male,

0:11:210:11:23

cos he doesn't spend very much time in the nest.

0:11:230:11:25

And if it's fleshy, it's a female.

0:11:250:11:27

-That's a female.

-That's a definite female!

0:11:300:11:32

-Would you like to let this one go?

-Yeah, I'd love to.

0:11:320:11:35

Just place your hand out flat. I'll just pop it on there...

0:11:350:11:38

Oh, brilliant! I hope she makes it to Africa and back!

0:11:380:11:41

Yeah, fingers crossed!

0:11:410:11:43

In August, the flow of swallows and martins back to Africa begins,

0:11:430:11:48

from Scotland down to the English Channel.

0:11:480:11:52

The first sign is when they gather on telegraph lines.

0:11:520:11:56

It's now mid September, and I've come to the south coast of England,

0:11:560:12:01

to Icklesham in East Sussex.

0:12:010:12:03

And the reason I'm here are these.

0:12:030:12:06

This reed bed is the final stopover point

0:12:060:12:09

for tens of thousands of swallows and sand martins

0:12:090:12:12

before they leave the country for the winter.

0:12:120:12:16

The reeds are a safe roost for the night,

0:12:160:12:19

and the sky is full of food

0:12:190:12:20

for a final meal before crossing the Channel.

0:12:200:12:25

In the late afternoon, the swallows start to gather over the reed beds.

0:12:250:12:29

But even if you watch them every day,

0:12:290:12:32

it's impossible to predict how many will arrive.

0:12:320:12:35

The reserve is run by Phil Jones.

0:12:350:12:38

I love watching it.

0:12:380:12:39

I mean, I can sit and watch it every night.

0:12:390:12:42

It's just a mass, the sky can be absolutely full of them.

0:12:420:12:45

They tend to take the evasive actions

0:12:450:12:48

as the birds of prey come through. Hobbies and sparrowhawks

0:12:480:12:51

and even merlin will come and pick off

0:12:510:12:54

the odd young, inexperienced bird.

0:12:540:12:56

It sounds like they're just a little snack for all sorts of predators.

0:12:560:13:00

Unfortunately, they are. Hobbies, we think, follow the flock,

0:13:000:13:05

and a hobby is actually a bird of prey that is a migrant in itself.

0:13:050:13:08

So they're going to Africa, as well.

0:13:080:13:10

It's very spectacular to see,

0:13:150:13:17

cos they'll come in huge groups of 100, 200 at a time.

0:13:170:13:21

It's just incredible to watch.

0:13:210:13:23

And how do you feel when you see the last lot of swallows

0:13:270:13:30

departing our shores?

0:13:300:13:31

Very depressed!

0:13:310:13:33

It's a sign of winter, it's a sign that autumn is really here and gone.

0:13:330:13:37

You know winter has arrived once your last swallows have gone.

0:13:370:13:40

-Still, it's a fantastic spectacle to usher in the winter.

-Brilliant.

0:13:400:13:44

Absolutely brilliant, and we enjoy it ever year.

0:13:440:13:47

Superb, absolutely superb.

0:13:520:13:55

Now, just think of this.

0:13:550:13:56

You're up in your grandfather's loft, you find an old lamp.

0:13:560:13:59

You've got to rub it, haven't you?

0:13:590:14:01

And a genie comes out, and it grants you one of your fantasies.

0:14:010:14:05

One of mine clearly would be to just be a swallow

0:14:050:14:08

for just a couple of minutes.

0:14:080:14:10

I mean, imagine it. Wings of burnished blue,

0:14:100:14:12

careening across the water surface like some sort of avian jet fighter.

0:14:120:14:17

It would undeniably be fantastic!

0:14:170:14:20

Now, we're a quarter of the way through our Top 40.

0:14:200:14:23

Let's see what's scored points so far.

0:14:230:14:25

At number 40, what a songster! Noisy natterjack toads.

0:14:250:14:31

In at 39, supercharged ants' nests.

0:14:310:14:35

Lighting up our countdown at 38, it's glow worms.

0:14:350:14:39

And how cute are these?!

0:14:390:14:41

Number 37, urban foxes.

0:14:410:14:44

At 36, our marvellous moths.

0:14:440:14:48

And when they're this beautiful, that really is a wildlife spectacle.

0:14:480:14:52

35, swimming with seals.

0:14:520:14:55

And here's a favourite of mine, at number 34, the high tide roost.

0:14:550:15:00

That's a lovely sight, these birds up in the sky there.

0:15:000:15:03

And 33, the stunning colours of Scotland's machair.

0:15:030:15:08

High impact combat at 32, with rutting goats.

0:15:080:15:11

And 31, you sexy thing, it's swarms of swallows!

0:15:130:15:17

Time for a joke, always fancied myself as a comedian, here we go!

0:15:230:15:27

My local Indian restaurant has started serving chicken tarka.

0:15:270:15:31

it's like chicken tikka, only it's just a little 'otter!

0:15:310:15:36

Boom boom!

0:15:360:15:37

Terrible joke, but fantastic animal absolutely fantastic,

0:15:370:15:41

and if ever you're lucky enough to catch just a glimpse of one,

0:15:410:15:45

I promise you'll be in seventh heaven.

0:15:450:15:47

I can still remember the first moment

0:15:520:15:54

I came face to face with a wild otter.

0:15:540:15:56

A magic moment, that will stay with me forever.

0:15:560:15:59

And today I plan to relive that excitement

0:15:590:16:02

through someone who's never seen one before.

0:16:020:16:04

And it's not in some wilderness either,

0:16:040:16:07

but right under the nose

0:16:070:16:09

of Newcastle's busy international airport.

0:16:090:16:12

I've come today to meet an otter virgin,

0:16:120:16:14

local lad and actor Tim Healy,

0:16:140:16:16

a man who has not yet seen an otter.

0:16:160:16:18

Never seen one in my life, no. Only on the TV.

0:16:180:16:21

But I'm really looking forward to it.

0:16:210:16:23

If we do see one, it would be fantastic.

0:16:230:16:25

-If, if?! This is the place!

-Yeah?

0:16:250:16:28

I didn't think it would be round here,

0:16:280:16:30

I thought you were going to take me right over

0:16:300:16:32

to the wilds of Northumberland.

0:16:320:16:34

Right next to the airport seemed a bit strange.

0:16:340:16:37

Any minute now, a jet will be whanging overhead.

0:16:370:16:40

What I want to do now is to introduce you

0:16:400:16:42

-to a dark side of Tales From The Riverbank.

-Really?

0:16:420:16:46

Tim, this, you can squeeze in here,

0:16:460:16:49

-is an otter sprainting point.

-Really?

-Yeah.

0:16:490:16:54

Now, spraints, there's no polite way to say it, are otter poo.

0:16:540:16:58

-Otter poo!

-Cop a sniff of that.

-Yeah.

0:16:580:17:03

I can't believe... "What did you do today?" "I was sniffing otter poo."

0:17:030:17:08

What that tells me is obviously that there are otters here,

0:17:080:17:12

but also, this is fresh,

0:17:120:17:13

this has been put down in the last couple of days or so.

0:17:130:17:16

So, I mean, there are otters in this area,

0:17:160:17:18

-and they're here now, basically.

-Brilliant.

0:17:180:17:21

All WE have to do is find them.

0:17:230:17:25

So time to call in the help of Kevin O'Hara

0:17:250:17:28

from the Northumberland Wildlife Trust.

0:17:280:17:30

He knows every inch of the Big Waters reserve.

0:17:300:17:33

While we waited, there was plenty of other stuff knocking around,

0:17:350:17:40

giving us great views.

0:17:400:17:41

Water rail, snipe and kingfisher.

0:17:410:17:44

But not a sniff of an otter.

0:17:440:17:47

And things were getting desperate.

0:17:470:17:49

Would Tim remain an otter virgin?

0:17:510:17:54

There you go.

0:17:590:18:00

You got it?

0:18:000:18:02

-Yep.

-Yeah, there it is, it's come out again to the right.

0:18:020:18:07

Just going into the water there.

0:18:070:18:10

..its tail as it flicks over.

0:18:100:18:13

-Yeah.

-There it is.

0:18:130:18:15

-You've got two together.

-It's two together, isn't it?

-Brilliant.

0:18:180:18:23

Otters are well suited for aquatic hunting.

0:18:240:18:27

They can close their nostrils and ears whilst under water,

0:18:270:18:31

using their long whiskers to find fish, frogs, water voles.

0:18:310:18:34

They'll even take small wading birds.

0:18:340:18:37

And whilst they're mainly active at dusk and at night,

0:18:370:18:41

here at Newcastle, daylight views are pretty much guaranteed.

0:18:410:18:44

-It's shiny like a seal, you wouldn't think it was fur, would you?

-No.

0:18:470:18:51

It looks like skin, doesn't it?

0:18:510:18:53

It does, like a wet suit, innit? With the sun shining on it, as well.

0:18:530:18:57

Yeah.

0:18:570:18:59

Even at this distance,

0:18:590:19:00

you can appreciate how superbly adapted they are

0:19:000:19:03

for the aquatic environment,

0:19:030:19:05

-quicksilver in the water.

-Yeah.

0:19:050:19:08

When they catch these fish,

0:19:080:19:10

you just catch a glimpse when they come to the surface,

0:19:100:19:13

then they're down, they're swallowing whole,

0:19:130:19:15

a couple of crunch to kill them. Then they flip over on their back.

0:19:150:19:19

And the other thing that they do which endears them to us

0:19:190:19:23

is that they use their hands to hold their food,

0:19:230:19:26

-particularly if they bring it out on their back.

-Yeah.

0:19:260:19:30

This one's come a bit closer, that's what we always want.

0:19:300:19:33

-Yeah, you want one down here.

-We do. Never satisfied!

0:19:330:19:36

You want them singing and dancing, jumping through flaming hoops!

0:19:360:19:40

You want them playing together.

0:19:400:19:42

Well, little then did we know what was to follow!

0:19:420:19:45

The otters we had been watching came closer and closer

0:19:450:19:48

and entered the reed beds right in front of us.

0:19:480:19:51

-Oh!

-Brilliant, brilliant!

0:19:510:19:54

They give away here with the moorhens.

0:19:570:20:00

One of these birds climbed right to the top of one of the bulrushes,

0:20:000:20:04

and was peering down into the reeds.

0:20:040:20:06

Then, there was a little moorhen stampede,

0:20:060:20:09

and about four or five of the birds

0:20:090:20:12

have moved from one side of the reeds to the other.

0:20:120:20:15

We can hear the otter splashing around,

0:20:150:20:18

so they are literally a few metres in front of us.

0:20:180:20:22

What we are hoping is that they are going to cross this canal

0:20:220:20:26

that has been cut through the reeds in front of us.

0:20:260:20:28

There, there, there... See, see...

0:20:300:20:33

Can you see the otter?

0:20:360:20:38

Can you believe it? I've never known anything like that.

0:20:460:20:50

When it came out there, my heart started going.

0:20:500:20:53

-There it is.

-I know.

0:20:530:20:54

Then it came out and put its head up,

0:20:540:20:56

-and looked right at us, didn't it?

-Yes.

0:20:560:20:58

A little head came up ever so slightly.

0:20:580:21:00

"Yeah, I know where you are."

0:21:000:21:02

I dunno, it takes some beating, doesn't it, really?

0:21:020:21:05

-What do you think then, Tim?

-Fantastic, man.

0:21:070:21:10

-Points out of ten?

-Ten.

-Ten.

-Ten.

0:21:100:21:13

Ten.

0:21:130:21:14

Top banana.

0:21:140:21:16

Though otter populations remain fragmented,

0:21:180:21:21

it's now heartening to see these animals doing well,

0:21:210:21:24

and just like Tim, you never know.

0:21:240:21:26

Your first otter experience could happen much sooner than you think.

0:21:260:21:30

Now, you've been sending in your ideas via local radio and on the Web

0:21:330:21:38

and Radio Norfolk came up with a particularly interesting set.

0:21:380:21:41

There were common crane, definitely on my list, otters, and, of course,

0:21:410:21:45

the pink-footed geese here.

0:21:450:21:47

There was one thing they were absolutely dead set

0:21:470:21:50

had to be the best local spectacle.

0:21:500:21:52

At number 29, it's the rook roost.

0:21:520:21:56

OK. Rooks.

0:21:580:22:01

You're thinking unremarkable, if not to say boring, black, farmland birds.

0:22:010:22:07

A bit like crows.

0:22:070:22:08

I reckon I can make you change your mind,

0:22:080:22:12

and possibly even blow your socks off.

0:22:120:22:16

The spectacle is about a gathering storm, a tidal wave of birds.

0:22:180:22:22

At dusk, rooks and jackdaws head for a wood outside Norwich,

0:22:240:22:29

a communal roost, an urban jungle in the country with 40,000 inhabitants.

0:22:290:22:36

Before they roost up, the birds gather nearby,

0:22:360:22:40

and when numbers are sufficient, they leave as one giant life force.

0:22:400:22:45

Oh, check out here, come round.

0:22:450:22:47

Look at this against the setting sun.

0:22:470:22:49

A swirling mass, it's like someone has shaken a snow dome,

0:22:520:22:56

only all the flakes are black rather than white.

0:22:560:22:59

They are all whizzing up and flying over a trees,

0:22:590:23:02

some of them are landing.

0:23:020:23:04

I can see, for as far as my eye,

0:23:040:23:07

right from this tree all the way round,

0:23:070:23:10

all the way round to the wood is rooks and jackdaws.

0:23:100:23:14

Listen to the sound.

0:23:140:23:15

ROOKS AND JACKDAWS CAW

0:23:150:23:17

You can see, as well, there are bigger dots, the rooks,

0:23:230:23:27

and little dots, which are the jackdaws.

0:23:270:23:30

The really high pitched call is the jackdaws,

0:23:300:23:34

and the lower one, the "caw, caw, caw" is the rook.

0:23:340:23:38

They are everywhere!

0:23:380:23:40

ROOKS AND JACKDAWS CAW

0:23:400:23:43

What a sight, unbelievable.

0:23:500:23:52

A whole wall, cathedral of sound, birds everywhere. Just unbelievable.

0:23:520:23:57

You know what, I've loved it so much, I'm gonna go to bed now,

0:23:570:24:01

and I'm coming back before dawn to see them leave tomorrow morning.

0:24:010:24:04

I want some more.

0:24:040:24:06

Early morning, and the birds are stirring, ready to leave the roost,

0:24:150:24:20

but not before they've put on another breathtaking aerial display.

0:24:200:24:24

What an incredible sight. 30, 40,000 rooks and jackdaws up in the air.

0:24:370:24:42

It looks like a bonfire, and someone's bashed it,

0:24:420:24:46

and they're all tiny little pieces of ash.

0:24:460:24:49

HE CHUCKLES

0:24:490:24:52

Of course, this is only really a winter phenomenon between November and February.

0:24:520:24:56

After that, they will split into their separate colonies or rookeries to start breeding.

0:24:560:25:02

They are a very early breeder.

0:25:020:25:04

But for now, what an amazing sight.

0:25:040:25:07

Look at them, just spiralling,

0:25:070:25:09

dropping down off the trees, taking off again.

0:25:090:25:12

This site has been used for hundreds of years.

0:25:120:25:16

They are very, very faithful to this particular woodland.

0:25:160:25:19

Coming back every November, doing this, every night.

0:25:190:25:23

Come on, if you are looking for a spectacle,

0:25:230:25:27

this has to be one of the best I have ever seen. It's so impressive.

0:25:270:25:31

No one really knows why the birds gather in such numbers.

0:25:340:25:38

It could be for security,

0:25:380:25:40

or even a way of exchanging information

0:25:400:25:43

about potential feeding areas.

0:25:430:25:45

Ploughed fields are a favourite haunt.

0:25:450:25:48

To some, rooks remain a farmland pest.

0:25:480:25:51

They have been persecuted for centuries.

0:25:510:25:54

As far back as Henry VIII,

0:25:540:25:55

there were serious attempts at extermination,

0:25:550:25:58

but numbers now are on the up,

0:25:580:26:00

with well over a million pairs nationally.

0:26:000:26:03

This spectacle gets under your skin,

0:26:040:26:06

so I'm back again for the evening display

0:26:060:26:09

in the company of author, naturalist and rook fan, Mark Cocker.

0:26:090:26:13

It's the calm before the storm, isn't it?

0:26:130:26:15

It is. That's one of the wonderful things about it. It is like a drama.

0:26:150:26:20

You are actually able just to wait,

0:26:200:26:23

and let it build up, and it does build up.

0:26:230:26:25

It's that fantastic sense of anticipation that you have.

0:26:250:26:30

Every night, you have success.

0:26:300:26:32

And as the light falls, the birds arrive.

0:26:320:26:36

You can see them coming now, look.

0:26:360:26:38

They're up, yes, they're up.

0:26:380:26:40

Oh, wonderful.

0:26:400:26:41

Fantastic. I often think of them,

0:26:410:26:43

because you can't see them very clearly,

0:26:430:26:46

that they remind me of a shoal of fish or something.

0:26:460:26:49

They don't even really look like birds,

0:26:490:26:51

apart from this fantastic sound that you can hear.

0:26:510:26:53

ROOKS CAW

0:26:530:26:56

-The decibels have gone through the roof.

-Yes. Fantastic.

0:26:560:27:01

This is only a tiny part. If you look across there,

0:27:010:27:04

-you've still got them pouring off the fields.

-Yes.

-It's fantastic.

0:27:040:27:07

It's like a river of birds.

0:27:070:27:09

Yes. 40,000 birds, that's lot of a stress on this tree.

0:27:090:27:15

Yes, well you're talking, eventually,

0:27:150:27:18

about 25 tonnes of birds in the air at one time.

0:27:180:27:22

-It's amazing, looking at it like that.

-Yeah.

0:27:220:27:24

Do you think they have special places where they go each night,

0:27:240:27:28

each individual bird or pair?

0:27:280:27:30

Yes. What's extraordinary,

0:27:300:27:32

to us it looks like a maelstrom of 30,000 birds,

0:27:320:27:36

yet every couple ends up sitting next to one another

0:27:360:27:41

at the end of the night.

0:27:410:27:43

They snuggle down.

0:27:430:27:45

That shows that, amongst all this seeming chaos,

0:27:450:27:48

there is a kind of order taking place,

0:27:480:27:51

which is pretty special in itself.

0:27:510:27:54

I think of it as a kind of alchemy.

0:27:540:27:57

I think of it as making gold from base metal.

0:27:570:28:00

Here's this bird, this incredibly ordinary,

0:28:000:28:04

and in many ways, despised bird,

0:28:040:28:06

and yet out of it, they create this fantastic spectacle,

0:28:060:28:09

which happens here every night. I think it's wonderful.

0:28:090:28:13

I think that's 24 carat gold. I have to agree with you, sir.

0:28:130:28:17

Fabulous, but I've got to tell you, there's better to come.

0:28:230:28:27

Do join us again next time for some more of Nature's Top 40.
