0:00:03 > 0:00:10on this sunny evening, and we have got plenty of drama, and a species
0:00:10 > 0:00:15new to Springwatch, the stone chap. We will bring you some fabulous
0:00:15 > 0:00:20mammals and one of my favourites, bottlenose dolphins. They will take
0:00:20 > 0:00:30a close-up look at one of the UK's rarest words, the enigmatic and
0:00:30 > 0:00:51
0:00:51 > 0:01:00acrobatic chough. Welcome, it is from the beautiful RSPB reserve
0:01:00 > 0:01:05here. It is a super sunny evening, there are 13 or 14 clouds in the
0:01:06 > 0:01:11sky, that is the limit, it is fantastic! The weather is set to be
0:01:11 > 0:01:17fair for the remainder of the week, fingers crossed. It has been a
0:01:17 > 0:01:23beautiful day, and it is easy to think that that makes spring a
0:01:23 > 0:01:30distant memory. But this time last week, we were standing in the
0:01:30 > 0:01:36pouring rain. That was Tuesday. And Monday. But it was a late spring,
0:01:36 > 0:01:41and it has been the coldest spring for 50 years. That has affected many
0:01:41 > 0:01:47of our animals, including birds. Especially nesting birds. Let's
0:01:47 > 0:01:57catch up with one of them, the great tips. That is how we left the checks
0:01:57 > 0:01:58
0:01:58 > 0:02:03on Thursday. What a difference a few days makes. This was then yesterday.
0:02:03 > 0:02:09Unbelievable, how much they have grown. A lot of flapping of wings, a
0:02:09 > 0:02:13lot of stretching. One of the slightly bigger ones has been going
0:02:13 > 0:02:23to the entrance of the nest quite a lot, so we were predicting they
0:02:23 > 0:02:28would fledge. Have they? Let's take a look at the nest live. No, they
0:02:28 > 0:02:36haven't. They are still there. They are looking very strong and healthy,
0:02:36 > 0:02:42a lot of activity going on. My prediction is tomorrow. They are
0:02:42 > 0:02:46still getting plenty of food. There are only five of them, when they
0:02:46 > 0:02:53leave the nest, the survival rate is much higher now that few of them are
0:02:53 > 0:02:59leaving the nest. They too well once they get out. Tomorrow, possibly. We
0:02:59 > 0:03:03have got another new bird tonight, but go live to its nest. It is on
0:03:03 > 0:03:12the side of a tree, it is a domed nest, it is well hidden in amongst
0:03:12 > 0:03:19the Ivy. You can see the female bird peeping out, it is a Wren. How she
0:03:19 > 0:03:26goes. There is a brood of young in there, she has been feeding them all
0:03:26 > 0:03:30day. They are a small, familiar bird, but they have got a big voice,
0:03:30 > 0:03:36they produce a complex trilling sound that can be heard over a
0:03:36 > 0:03:40kilometre away, and they pump the song out at 92 decibel is. They are
0:03:40 > 0:03:48city Rockers, they pump out the volume from the hedgerow, they
0:03:48 > 0:03:53really do. The male ones make between five and eight nests and
0:03:53 > 0:03:59tempt the females in. She lined the nest and lays the X, then she brings
0:03:59 > 0:04:08up the junk whilst the mail tents and other female into one of his
0:04:08 > 0:04:13nest. It is easy to forget how small it is, because we have got close-up
0:04:13 > 0:04:19cameras on them. They are doing really well at the moment, but
0:04:19 > 0:04:29sadly, one of our birds is not doing quite so well. Let's go live to the
0:04:29 > 0:04:34
0:04:34 > 0:04:37blackbirds best. The female is quietly, but you might be able to
0:04:37 > 0:04:44see there are not quite so many as before. Let's catch up on what
0:04:44 > 0:04:49happened. They were looking great, they were being fed. Terrific amount
0:04:49 > 0:04:55of food being brought in. There were five of them to begin with, but they
0:04:55 > 0:05:01have hatched at different times, which is unusual. This is what we
0:05:01 > 0:05:07saw at 5:20am. That is the mother taking out one of the chicks that
0:05:07 > 0:05:13had died. Very sad, but very good nest hygiene, because the mother
0:05:13 > 0:05:20needs to take any chick that dies out, because it might attract flies
0:05:20 > 0:05:24or predators. Why did that one pass away? It was the smallest. They
0:05:24 > 0:05:30hatched asynchronously, and the others would have been bigger. One
0:05:30 > 0:05:35disappears like that, there will be more food for the others, so it is
0:05:35 > 0:05:39fingers crossed for the others. will be keeping an eye on the life
0:05:39 > 0:05:49cameras through the programme. If anything dramatic happens, we will
0:05:49 > 0:05:51
0:05:51 > 0:06:01cut into it. We will try to bring it and day on the red button and on the
0:06:01 > 0:06:02
0:06:02 > 0:06:08website. Let's have a quiz. We have been in the studio, filming. Try and
0:06:08 > 0:06:15tell us what this is. It looks like a space alien. It looks odd. What a
0:06:15 > 0:06:21face! Only a mother could love it! If you think you know what it is,
0:06:21 > 0:06:26get in touch on the Internet, on Facebook or on Twitter. From one of
0:06:26 > 0:06:31my least favourite creatures to one of my favourites, bottlenose
0:06:31 > 0:06:41dolphins. We went up to Scotland to find out why a group of them had
0:06:41 > 0:06:50
0:06:50 > 0:06:55chosen a surprising area to hang out I am in the heart of Aberdeen, and
0:06:55 > 0:07:03thanks to the oil and gas industry, this harbour is one of the busiest
0:07:03 > 0:07:06in the country full --. I am told it is a great place to see one of our
0:07:06 > 0:07:13favourite marine mammals, the bottlenose dolphin, but what are
0:07:14 > 0:07:18they doing here? I am hoping to find out. It seems extraordinary that
0:07:18 > 0:07:22there are dolphins swimming in these waters. Aberdeen has had a lively
0:07:22 > 0:07:28fishing industry for centuries, but since the discovery of North Sea
0:07:28 > 0:07:38oil, this sport has grown and grown. Nowadays, the votes servicing the
0:07:38 > 0:07:49
0:07:49 > 0:07:53rigs form a steady flow of traffic. boats, all of the people, the hustle
0:07:53 > 0:08:03and bustle, I thought they had got it wrong, but I am surrounded by
0:08:03 > 0:08:04
0:08:04 > 0:08:14them! Here we are, here is one. They are wonderful animals. When you see
0:08:14 > 0:08:16
0:08:16 > 0:08:20one, it puts a smile on your face. Bottlenose dolphins inhabit warm,
0:08:20 > 0:08:24temperate seas worldwide, but those living off Scotland's coast have
0:08:24 > 0:08:28ventured further north than any others. To deal with the colder
0:08:28 > 0:08:33temperatures, they grow much bigger. A thick layer of blubber helps
0:08:33 > 0:08:39insulate them from the cold. Some of the animals grow to nearly four
0:08:39 > 0:08:49metres long. It is amazing to find such big mammals living in such a
0:08:49 > 0:08:55human environment. It is unbelievable, you have got the
0:08:55 > 0:09:05harbour wall, the docks, the city of Aberdeen, and these waters, they are
0:09:05 > 0:09:05
0:09:06 > 0:09:10alive with bottlenose dolphins. There must be 50 or 60 animals here.
0:09:10 > 0:09:14Why are they venturing into this busy harbour? Biologist David Luiz
0:09:14 > 0:09:21so is part of a research team from the University of Aberdeen that is
0:09:21 > 0:09:27studying them. We are starting to understand what is going on, it is
0:09:27 > 0:09:34interesting. They are part of the larger north-east Scotland
0:09:34 > 0:09:42population, which is just shy of 200 animals. They go all the way down to
0:09:42 > 0:09:47Newcastle. That dolphin there was in Newcastle three months ago. We can
0:09:47 > 0:09:53take pictures of them and recognise individuals. By photographing the
0:09:53 > 0:09:59dolphins, David and his colleague can analyse any distinguishing
0:09:59 > 0:10:02features on their dorsal fins. Previous injuries, differences in
0:10:02 > 0:10:07colour and shape or help them identify individual dolphins and
0:10:07 > 0:10:15plot their movement down the coast. Taking photographs is not the only
0:10:15 > 0:10:21way that David can build a clearer picture of what is going on. Using a
0:10:21 > 0:10:30special underwater microphone, he can eavesdrop on the dolphins.
0:10:30 > 0:10:35you hear anything? Absolutely, lots going on right now. All of the
0:10:35 > 0:10:42clicking is essential for navigating these busy waters. We have got 20
0:10:42 > 0:10:47dolphins around, and every one of them uses this to say. Using
0:10:47 > 0:10:50echolocation, they listened for the echo of their calls as a way of
0:10:50 > 0:10:57measuring the position of any obstacles, which is vital in a busy
0:10:57 > 0:11:06shipping area. But there is something else going on as well.
0:11:06 > 0:11:12high-pitched squeaking noise. Yes, a whistling. It is incredible. That is
0:11:12 > 0:11:17their own language. That is right, it is communication. The whistles
0:11:17 > 0:11:22might seem random, but dolphins all have their own unique sound. It
0:11:22 > 0:11:32helps them identify each other. The dolphins in Aberdeen harbour are
0:11:32 > 0:11:36socialising. How does that work with all of the ships coming past? Rust
0:11:36 > 0:11:41interfere with their acoustic indication. When you talk in a noisy
0:11:41 > 0:11:49room, sometimes you speak louder, sometimes you repeat yourself. It is
0:11:49 > 0:11:53the same principle. They will first saw, and it will be repeated.
0:11:53 > 0:11:57this reveals is that these dolphins are not just travelling through the
0:11:57 > 0:12:00harbour, they are hanging around and talking to each other. That is
0:12:01 > 0:12:07despite the fact they are having to shout to make themselves heard above
0:12:07 > 0:12:14the noise. But what has brought them here? To find out, I will need to
0:12:14 > 0:12:22get a better view of what is going Do you think that those dolphins
0:12:22 > 0:12:31could evolve to be slightly deaf? They did a study on the mice on the
0:12:31 > 0:12:36Underground, that is what might have hear the announcement? ! It was
0:12:36 > 0:12:41because of the constant loud noises? I do not know. Dolphins are
0:12:41 > 0:12:50different, their hearing is acute, seven or eight times better than
0:12:50 > 0:12:54ours, we hear to 20,000 hertz, but they can hear up to 150,000. It is a
0:12:54 > 0:12:58noisy place, all of the propellers, everything, they are probably
0:12:58 > 0:13:05filtering out the sounds. When I am at home, I do not hear my dogs
0:13:05 > 0:13:10barking. People living next door to railway lines do not hear them. That
0:13:10 > 0:13:14is what they must be doing, because sound is such an important part of
0:13:14 > 0:13:21their world, they could not exist there unless they could cope with
0:13:21 > 0:13:25the acoustic intrusions. They have adapted. Let's check up with the
0:13:26 > 0:13:31jackdaws, it has been a gym addict story. As you know, the resident
0:13:31 > 0:13:37chicks have been attacked by intruders regularly. What happened
0:13:37 > 0:13:41over the last 24 hours? There has been a bit of respite. The intruders
0:13:41 > 0:13:46have been in a queue times but the attacks have been less brutal, and
0:13:46 > 0:13:53both chicks have been fighting back. That is the parent bird scaring them
0:13:53 > 0:13:57off. Let's think about what the parents must be going through. Every
0:13:57 > 0:14:05time they leave the chicks, they are vulnerable. But they have to keep
0:14:05 > 0:14:09believing them to get food. They are four weeks old, they will not fledge
0:14:09 > 0:14:14until they are at least five weeks old, so they have got another week
0:14:14 > 0:14:18of possibly being attacked, but the parents have to keep going out and
0:14:18 > 0:14:26getting food for them. There has been another interesting turn of
0:14:26 > 0:14:31events. Those are not the parents, those are the intruders. Look at
0:14:31 > 0:14:35what they are doing. They are bringing in nesting material, they
0:14:35 > 0:14:43are not attacking the chicks. They look like they are almost trying to
0:14:43 > 0:14:49move in. Just outside the barn where the nest box is, these are the same
0:14:49 > 0:14:55two birds, the same intruders, the Bonnie and Clyde pair, they are
0:14:55 > 0:15:01still looking around, prospecting for another nest site. There are
0:15:01 > 0:15:07instinctive find a nest is so strong, if they cannot use the nest
0:15:07 > 0:15:11box, they feel compelled to find somewhere else. This backs up our
0:15:11 > 0:15:15theory. These attacks have been constant. We postulated that the
0:15:15 > 0:15:19birds coming in are lower down in the social hierarchy in this group
0:15:19 > 0:15:22of jackdaws, that they don't have a nest, that nest sites are in short
0:15:22 > 0:15:26supply and they're desperate to get one. The fact that they're adding
0:15:26 > 0:15:30material before they even own it and then constantly looking into every
0:15:30 > 0:15:34nook and cranny for a nest seems to back up that theory. It's a bit rude
0:15:34 > 0:15:38to move in when someone's already in there. You think they'd wait till
0:15:38 > 0:15:42the end of the season and occupy it. If they could turf them out they
0:15:42 > 0:15:47could stay in the box. They would stake their claim through to the
0:15:47 > 0:15:52beginning of the winter and then nip back in next year. Too late this
0:15:52 > 0:15:59year, though. Yes this year. But not too late to onning piet space.
0:15:59 > 0:16:01look at them live. They're sleeping but they are doing quite well. We've
0:16:02 > 0:16:04been watching them throughout the day. They're strong and quite
0:16:04 > 0:16:08healthy. They're getting fed regularly. At the moment, they're
0:16:08 > 0:16:12doing all right. Fingers crossed. They may have another week or so to
0:16:12 > 0:16:21go. Let's hope that those attacks don't get worse. The other thing is
0:16:21 > 0:16:26it's quite a shallow nest. One thing that leads it a lot of jackdaw
0:16:26 > 0:16:30deaths is that they fledge too early. Typically they prefer deeper
0:16:30 > 0:16:39nests. That box is shallow. We will have to keep our eye on them. At the
0:16:39 > 0:16:47top of the show we promised you a species new to Springwatch. We never
0:16:47 > 0:16:53showed you a nest like this. It's on the ground and made of grass. There
0:16:53 > 0:17:03is a brood of youngsters in there. They have been busy all day to-ing
0:17:03 > 0:17:07and fro-ing. They are resting quitely at this time. They are a
0:17:07 > 0:17:10delightful little birds. This is the female. Less brightly coloured than
0:17:10 > 0:17:19the male. She spends more time on the nest and needs to be well
0:17:19 > 0:17:24camouflaged. He is a show off. He has very bright orange colouring.
0:17:24 > 0:17:27And a distinctive white colour. Globally speaking, this is a hugely
0:17:27 > 0:17:32successful species. Can you find them all across Europe, all across
0:17:32 > 0:17:36Asia, all the way into Japan and right the way down through Africa as
0:17:36 > 0:17:42far as South Africa. Birds of open country don't need water, they can
0:17:42 > 0:17:52be in quiet dry places. Nest on the ground and their nests are very well
0:17:52 > 0:17:55
0:17:55 > 0:18:01hidden. Very handsome bird.The female. They are insect ivores. In
0:18:01 > 0:18:06the winter when they go to the coast they take a few seeds. I have to say
0:18:06 > 0:18:10that between 2005, 2010 they declined by about 60% in this
0:18:10 > 0:18:15country. It's been the hard winters. But these things can have up to four
0:18:15 > 0:18:21broods a year so they can bounce back quickly. Let's look at some of
0:18:21 > 0:18:25our live cameras. The water rail? There it is. Sitting on the nest.
0:18:25 > 0:18:29Martin was saying yesterday that the water rail was making such
0:18:29 > 0:18:33interesting nices that he -- noises that he thought maybe it was
0:18:33 > 0:18:38communicating with the chicks that were about to hatch. Clearly he was
0:18:38 > 0:18:42wrong. Do make a low vocalisation. Birds do communicate with their eggs
0:18:42 > 0:18:46once they start pipping inside the egg. On this occasion she must have
0:18:46 > 0:18:50been communicating with the male. Because she's still incubating full
0:18:50 > 0:18:53on. I have a feeling that the water rail might be like last year's
0:18:53 > 0:18:57sandpiper, that we keep saying they're going to hatch and they
0:18:57 > 0:19:03hatch on the last day of the series. I hope they do. That would be a
0:19:03 > 0:19:07highlight. So want to see the young. Let's look at the marsh cam live. Is
0:19:07 > 0:19:12there anything on it? Not at the moment. That looks pretty. Look at
0:19:12 > 0:19:17the light on there. It's a bit of a Constable. It just needs an old
0:19:17 > 0:19:23wagon and that would be great. Perhaps a rusty Cortina. More of a
0:19:23 > 0:19:28Banksy than a Constable if that were the case. We have seen a lot of the
0:19:28 > 0:19:32grey heron. Over the last few days we have such amazing footage of it
0:19:32 > 0:19:42that we thought we'd put it all together and have a real close-up
0:19:42 > 0:19:48
0:19:48 > 0:19:58look at what is a really special the largest avian predators are
0:19:58 > 0:20:00
0:20:00 > 0:20:10returning ready for another day's hunting. Herons are opportunistic
0:20:10 > 0:20:12
0:20:12 > 0:20:18They're happy to see fish, amphibians, insects, small mammals
0:20:18 > 0:20:26and even water birds on the menu. Luckily for those ducklings, this
0:20:26 > 0:20:36heron seems intent on fishing. Standing a metre tall, the grey
0:20:36 > 0:20:42
0:20:42 > 0:20:52heron cuts a majestic figure as it their long neck which sprysingly has
0:20:52 > 0:20:53
0:20:53 > 0:20:58the same number of vertebrae as other birds. But in herons the sixth
0:20:58 > 0:21:02vertebrae is mootified enabling the neck to kink into a characteristic S
0:21:02 > 0:21:06shape. From this posture the neck unfurlz
0:21:06 > 0:21:16in a powerful, lightning-quick in a powerful, lightning-quick
0:21:16 > 0:21:36
0:21:36 > 0:21:41in a powerful, lightning-quick Herons are visual predators.
0:21:41 > 0:21:51Forward-facing eyes give them acute vision and allow them to strike with
0:21:51 > 0:22:21
0:22:21 > 0:22:28you notice the way the heron flicked its head from side to side for the
0:22:28 > 0:22:33final strike. Come with me. We are now down by the marsh area. That's
0:22:33 > 0:22:36the lovely area. That's where the heron has been the we've seen otters
0:22:36 > 0:22:42and all sorts out there. We have been filming other things with the
0:22:42 > 0:22:47heron. Look at what it's been up to today - washing him or herself. Like
0:22:47 > 0:22:52all birds they have to keep their feathers in tip-top condition. They
0:22:52 > 0:22:58get right under the water. Oh, look at that! I've never seen one go in
0:22:58 > 0:23:03quite so deeply as that. They have to dry out beautifully. Herons to me
0:23:03 > 0:23:08always look like grumpy old Dickensian gentlemen with a too
0:23:08 > 0:23:13tight waist coat. They always look a bit fierce. They have scary eyes.
0:23:13 > 0:23:21Michaela was saying that they have a very Catholic diet, they eat all
0:23:21 > 0:23:27sorts of things. But I've never seen one eat this. Here say photograph
0:23:27 > 0:23:34from Kay. It is eating a mole. How on earth did it find a mole?
0:23:34 > 0:23:41Fascinating. This marsh looks as though it's been there forever, but
0:23:41 > 0:23:45it hasn't. It was actually created by the RSPB here just 13 years ago.
0:23:45 > 0:23:49Now it's teeming with life. Things that we love to see down there and
0:23:49 > 0:23:57also there are some things that we don't like to see. Look at the crew
0:23:57 > 0:24:01here behind me. There's a clue. You can smile chaps.
0:24:02 > 0:24:08Notice the hair nets. We have been eat an live by midges here. That
0:24:08 > 0:24:15brings us neatly to that quiz. I asked you - what a funny little
0:24:15 > 0:24:21creature was. J -- jules you got it right. Let's remind ourselves what
0:24:21 > 0:24:29it was. Here it is. The strange, science
0:24:29 > 0:24:34fiction looking thing. It is a midge larvae. The midges have been driving
0:24:35 > 0:24:40us crazy. We thought, come on, let us just explore their life because
0:24:40 > 0:24:43they are fascinating creatures. So this is what we have gone into
0:24:43 > 0:24:47macroworld and all of this is filmed in there.
0:24:47 > 0:24:51Now this is the larvae. The eggs are laid under water and they hatch into
0:24:51 > 0:24:57this strange looking creature. You can see it's feeding there. These
0:24:57 > 0:25:03are only about eight millimetres long. They are quite predatory too.
0:25:03 > 0:25:09Here they are, rising up towards the surface. This is moving into the
0:25:09 > 0:25:14next stage of their life cycle. A bit like butt irflies they go into a
0:25:14 > 0:25:20-- butterflies, they go into a pupa stage. This floats up to the surface
0:25:20 > 0:25:26of the water. Look at that one on the right, it looks like an alien
0:25:26 > 0:25:31face. Here is the moment of emergence. This is the adult midge
0:25:31 > 0:25:36coming out of that pupal case which is under water. This took about two
0:25:36 > 0:25:42minutes in total. We've speeded it up. Watch its feet as they come out
0:25:42 > 0:25:47there. They will just touch the surface of the water but it won't
0:25:47 > 0:25:51sink in because the surface tension is too great. So it can walk on the
0:25:51 > 0:25:55surface of the water. They have been causing us so much misery. This is a
0:25:55 > 0:25:59mass hatch going on. That's the sort of thing that you may see on lakes
0:25:59 > 0:26:04and rivers around you, that mass hatch. Of course, they're irritating
0:26:04 > 0:26:11for us, but this is a vital food resource for lots and lots of
0:26:11 > 0:26:17wildlife. We've seen this going on here, last week, when it was wet and
0:26:17 > 0:26:21rainy, huge numbers of swallows sweeping low over the water, because
0:26:21 > 0:26:25there's a hatch of midges going on. They're emerging from the surface
0:26:25 > 0:26:28and the agile swallows sweep over the water, grabbing them, picking
0:26:28 > 0:26:33them off the surface, or just as they're hatching out. That's
0:26:33 > 0:26:41something you may well have seen in rivers and lakes around you.
0:26:41 > 0:26:45Gorgeous sight. They're a very important food resource.ive always
0:26:45 > 0:26:50wonder with swallows, if they're catching flies and beetles, doesn't
0:26:50 > 0:26:56it hurt their mouths? Chris probably knows. Not just birds feeding onning
0:26:56 > 0:27:01midges. Other -- on midges. Other creatures too, like this.
0:27:01 > 0:27:05Dragonflies. Yesterday we looked at the dragon fly larvae, hugely
0:27:05 > 0:27:10predatory under water. This has climbed up this stem of grass and
0:27:10 > 0:27:15it's hatched out. The adult has emerged. Here it is. It's a four
0:27:15 > 0:27:18spotted chaser. Again, incredibly prolific predator. They fly around
0:27:18 > 0:27:23and grab those midges from out of the air in their legs and munch them
0:27:23 > 0:27:27in the sky. Here's a damsel fly. Can you tell the difference, the damsel
0:27:27 > 0:27:32fly holds its wings over its back, whereas the dragon fly sticks them
0:27:32 > 0:27:36out at 90 degrees. Very interesting things midges. Everything has its
0:27:37 > 0:27:46place. Now, let's look now at another watery animal, that's very
0:27:47 > 0:27:55
0:27:55 > 0:28:01close to all our hearts, but one It's been a long time coming this
0:28:01 > 0:28:07year, but spring has finally arrived on the river Derwent. Already the
0:28:07 > 0:28:17first signs of new life have appeared. A family of mallard
0:28:17 > 0:28:23
0:28:23 > 0:28:29nation's most popular and familiar birds. They could even be one of the
0:28:29 > 0:28:34first wild animals many people will meet. But there's more to this
0:28:34 > 0:28:38tranquil scene than first meets the eye. Because the secret to the
0:28:38 > 0:28:46mallard's success is much more dramatic and even sinister than
0:28:46 > 0:28:51might be imagined. These ducks have chosen a particularly prestigious
0:28:51 > 0:28:55location as their home, Chatsworth House is set in the heart of the
0:28:56 > 0:29:05Peak District in Derbyshire. It's here that a three-year study has
0:29:06 > 0:29:10
0:29:10 > 0:29:17helped uncover the hidden world of widespread water bird. It's thought
0:29:17 > 0:29:21that there are more than 100,000 pairs breeding here. They're highly
0:29:21 > 0:29:24adaptable birds which thrive in ponds, lakes, rivers and wetlands.
0:29:24 > 0:29:29In fact, their main habitat requirement seems to be the chance
0:29:29 > 0:29:33to get their feet wet. Another key to their success is a
0:29:33 > 0:29:38Another key to their success is a very broad diet. They eat -- they
0:29:38 > 0:29:40dabble under water using their beaks to feel their way around and filter
0:29:40 > 0:29:46to feel their way around and filter to feel their way around and filter
0:29:46 > 0:29:50to feel their way around and filter out plant and animal matter. It is
0:29:50 > 0:29:56vital to keep waterproof, and they have an intricate feather structure
0:29:56 > 0:30:02and by rubbing their plumage with oil from a gland on their room.
0:30:02 > 0:30:09allows any water to run off their back. The counterfeiters underneath
0:30:09 > 0:30:16stay completely dry. One of the most striking things about ten is their
0:30:16 > 0:30:22sexual dimorphism. The males and females look very different. Their
0:30:22 > 0:30:26plumage is so different, they were once thought to be separate species.
0:30:26 > 0:30:33Females want to pair up with the most colourful males because it is a
0:30:33 > 0:30:39sign of vitality. The fittest males are also the first to come into
0:30:39 > 0:30:44breeding plumage, giving them a head start in the season. This pair have
0:30:45 > 0:30:53been happily paired up for a few months. Their courtship today is
0:30:53 > 0:31:02simple. A bit of head bobbing. But mating on the water has its
0:31:03 > 0:31:08challenges. This looks like a straightforward duck meat strake
0:31:08 > 0:31:14situation, but looks can be deceptive, because male mallards
0:31:14 > 0:31:19have a darker side. A Drake will often sneak away from his partner on
0:31:19 > 0:31:24the off chance of another mating. Nearby, a kind of males have not
0:31:24 > 0:31:28paired up this year. Pumped full of testosterone and looking for any
0:31:28 > 0:31:36opportunity to make, they will even resort to extreme methods to secure
0:31:36 > 0:31:39a partner. Unattached females are the most vulnerable targets. This
0:31:39 > 0:31:44one has already hatched ducklings, but now she is on her own as male
0:31:45 > 0:31:54birds do not help raise the youngsters. The male birds have
0:31:55 > 0:32:10
0:32:10 > 0:32:17Whilst trying to avoid her tissue was, she is forced to leave her
0:32:17 > 0:32:23vulnerable ducklings alone and unprotected. With so many males, she
0:32:23 > 0:32:33simply does not stand a chance. They persist until they get a chance to
0:32:33 > 0:32:35
0:32:35 > 0:32:40make. Also eventually, she does make it back to her ducklings. So why do
0:32:40 > 0:32:44these males perform this seemingly extreme behaviour? Because they have
0:32:44 > 0:32:50to sit and integrate their eggs, female mallards suffer a much higher
0:32:50 > 0:32:54mortality than males, there are not simple -- there are simply not
0:32:54 > 0:32:59enough to go around, so not all males are monogamous, there will
0:32:59 > 0:33:03always be spares, and extra pair copulation is their only option to
0:33:03 > 0:33:09get their genes into the next generation. This strategy persists,
0:33:09 > 0:33:18so it must work. Certainly for the extra pair, and for the species as a
0:33:18 > 0:33:22whole, which is one of the commonest wildfowl all across the world. As --
0:33:22 > 0:33:28as spring turns into summer, the ducklings grow up, and calm returns
0:33:28 > 0:33:33again. The next time you feed the ducks, remember the one secret to
0:33:33 > 0:33:39their success is more complex than you might imagine.
0:33:39 > 0:33:46What that film shows is that you cannot be in any way
0:33:46 > 0:33:50anthropomorphic, you cannot project our morals onto them, it is just the
0:33:50 > 0:33:57same with the jackdaw, you have got to be able to see clearly what is
0:33:57 > 0:34:01going on. You have got to analyse it in that way, a dispassionate way.
0:34:01 > 0:34:07Mallards are very common, they are perfect to get to grips with
0:34:07 > 0:34:12behaviour. You can pop down to the local park and see what they are up
0:34:12 > 0:34:18to, like this. When you are feeding bread or grain to your local
0:34:18 > 0:34:22mallards, the male ones will do this at the end, they rise up, they flap
0:34:22 > 0:34:29their wings and waggle their backside, and sometimes they will
0:34:29 > 0:34:33dip their peak into the water. Why? There has got to be a reason. It is
0:34:33 > 0:34:39a status thing, they show their fit this, and many species of duck do
0:34:39 > 0:34:45that. Let's go live, because we have got some live ducklings that have
0:34:45 > 0:34:51already hatched. There they are. They have just gone behind the
0:34:51 > 0:34:57reeds, we could not count them. Any familiar species like this which
0:34:57 > 0:35:05allow you to get close to them, it means it is a perfect opportunity to
0:35:05 > 0:35:11understand its behaviour, but they dispassionate. And empathetic. I
0:35:11 > 0:35:18will work on that! You are such a scientist! Let's have a look at the
0:35:18 > 0:35:25live cameras, with the female mallards sitting on Aix. She is very
0:35:25 > 0:35:34well camouflaged. She has been sitting on the nest all day. This is
0:35:34 > 0:35:39yesterday. Yesterday, it was quite hot, and it is sheltered. The sun is
0:35:39 > 0:35:44shining on it, and you can see she is hot. Our nest watchers have been
0:35:44 > 0:35:50watching them, and they said some days she does not go off the nest
0:35:50 > 0:35:56all day. Other days, like now, she goes off the nest sometimes for half
0:35:56 > 0:36:01an hour, or at the most, a couple of hours. So the day she does not go
0:36:01 > 0:36:10off, does she not drink or eat? normally go off every day. They
0:36:10 > 0:36:16cover the eggs over, and they go to water to drink, perhaps feed, have a
0:36:16 > 0:36:25clean, and go to the toilet. She does have to leave. The male one has
0:36:25 > 0:36:31gone. They are hanging out, so she has to do the duties. Before she
0:36:31 > 0:36:34starts to Lady X, it is about taking on as much body fat as possible,
0:36:34 > 0:36:40because she knows she has to get through a lean time. She does not
0:36:40 > 0:36:45want to leave the nest too much, because the eggs are vulnerable.
0:36:45 > 0:36:50is not quite so bad when it is warm, but on a cold day, they will lose
0:36:50 > 0:36:57some heat, and it is about incubating them. She hides them
0:36:57 > 0:37:04well. Very well. Let's check up on another bird, the dipper. This is
0:37:04 > 0:37:10where the family are nesting, a beautiful sight, the waterfall.
0:37:10 > 0:37:15week, we were not sure how many chicks were in there. There are two
0:37:15 > 0:37:22little beaks poking out. The adult is feeding them very well, a
0:37:22 > 0:37:31mouthful of food. I love the white paper that it has. You can see it
0:37:31 > 0:37:35bobbing away. It takes the food into the nest. If you look closely, there
0:37:35 > 0:37:44are four little beaks sticking out, so there are at least four chicks.
0:37:44 > 0:37:49It looks like... Will you say they will fledge tomorrow? Yes. There is
0:37:49 > 0:37:57a fledging frenzy going on tomorrow! It will be a busy day if
0:37:57 > 0:38:01that is the case! Let's go to the redstarts. In one of our nest boxes.
0:38:01 > 0:38:09We have got eight chicks in this box, a good clutch. They have all
0:38:09 > 0:38:14hatched. The adults have been very busy, taking in food. Lots of
0:38:14 > 0:38:19caterpillars, a 40% decline in larger moth species, which means
0:38:19 > 0:38:24caterpillars, but the redstarts are not having much trouble. This is a
0:38:24 > 0:38:31massive caterpillar. Do you think any of them will be able to swallow
0:38:31 > 0:38:36it? They will, it has gone down. The female has been bringing in plenty
0:38:36 > 0:38:43of food as well, a mixture of invertebrates. There seems to be
0:38:43 > 0:38:48lots of caterpillars. These words time the hatching perfectly. All of
0:38:48 > 0:38:51the young chicks appeared as soon as the weather got good. Lots of
0:38:51 > 0:38:57insects active in the warm weather, so they are doing well at the
0:38:57 > 0:39:03moment. All of them going strong. The female gets a bit agitated when
0:39:03 > 0:39:09the male one arrives. She makes a sharp screaming call and dashes out.
0:39:09 > 0:39:15Why is that? I do not know, but they do not like each other! I will
0:39:15 > 0:39:23research that. Welcome to my poetry corner, we need a bit of culture!
0:39:23 > 0:39:31John wrote the fire tale about redstarts. While in a quiet mood,
0:39:31 > 0:39:37and inward stirrer of shadowed melody, but on the rotten tree, the
0:39:37 > 0:39:45old Hedger returns, and chops the grain to stop the gap close by, the
0:39:45 > 0:39:50home where her blue eggs in safety life. Lovely. I have got a bit of
0:39:50 > 0:40:00cramp in my leg, I need to stretch! Absolute Philistine! From one
0:40:00 > 0:40:09fantastic bird to another iconic bird of Wales, a denizen of
0:40:09 > 0:40:16Anglesey, just up the road. This is South Stack, where the
0:40:16 > 0:40:25cliffs are a bustling seabird metropolis. Whilst guillemots crowd
0:40:25 > 0:40:30the ledges, deep inside, it is a rare member of the crow family.
0:40:30 > 0:40:37These quirky Corvettes are chuffed, which, unlike any other crow, have
0:40:37 > 0:40:42read beaks and legs. This family is one of only a handful living here.
0:40:42 > 0:40:48They are closely monitored and protect it. This nest camera offers
0:40:48 > 0:40:54a rare insight is chuffed is always nest in caves, mineshaft or crevices
0:40:54 > 0:40:57hidden away from prying eyes. They breed once they are three years old
0:40:58 > 0:41:07and have clutch sizes of between three and five eggs. This nest has
0:41:08 > 0:41:11
0:41:11 > 0:41:15four FM, all of whom appeared to be doing well. With their wings, they
0:41:15 > 0:41:25are masters of the air. The distinctive call can be heard as
0:41:25 > 0:41:41
0:41:41 > 0:41:44They live life on the edge. They restrict themselves to the perfect
0:41:45 > 0:41:51combination of a habitat with mild temperatures and short, grassy
0:41:51 > 0:41:56areas. As well as the Tufts here, and like to take advantage of the
0:41:56 > 0:42:02well manicured clifftop lawns. Such areas are essential, as they feed on
0:42:02 > 0:42:12insect larvae. Their curved bill is the perfect tool for plucking out
0:42:12 > 0:42:31
0:42:31 > 0:42:37leather jackets or crane fly larvae. The recent cold winter has been
0:42:37 > 0:42:41tough for the chuffed. But the signs are that numbers are only slightly
0:42:42 > 0:42:49down on last year. That is good news for this enigmatic and rather
0:42:49 > 0:42:59special bird. When I was a kid, I used to go out
0:42:59 > 0:43:01
0:43:01 > 0:43:08nesting. This bloke called Nigel called them by a different name.
0:43:08 > 0:43:18That game was first written down in the 1300s, and by 1643, it was only
0:43:18 > 0:43:18
0:43:18 > 0:43:27then that they added the F sound to chough. It is supposed to sound like
0:43:27 > 0:43:36the call. We should pronounce them the original name. Nigel would be
0:43:36 > 0:43:42chuffed! Do you remember we were talking about woodpeckers and how
0:43:42 > 0:43:49they were taking into nest boxes, even if they were reinforced? We
0:43:49 > 0:43:55have got a photo here from Pat. Caught in the act after she had
0:43:55 > 0:44:00taken precautions. This was the culprit paying a visit after he had
0:44:00 > 0:44:06taken the chicks, checking to see if he had left anything. It has gone in
0:44:06 > 0:44:11there like a bank robber. The metal plate has made no difference. You
0:44:11 > 0:44:17need a carbon fibre, bullet-proof nest box, as available on my
0:44:17 > 0:44:22website! It is a shame for the chicks! But the woodpeckers have got
0:44:22 > 0:44:27to eat as well. Do not be anthropomorphic, be pragmatic and
0:44:27 > 0:44:37scientific. I will work on that! This is the great spotted
0:44:37 > 0:44:43woodpecker. woodpecker.
0:44:43 > 0:44:48Listen! Yes, they're all down in. There I'm glad I'm not. It's a mess
0:44:48 > 0:44:52in there, I can tell you. There could be as many as six chicks.
0:44:52 > 0:44:56They've been in there for days. The adults are no longer taking their
0:44:56 > 0:44:59faecal sacks out. You know what that means. They are climbing on top of
0:44:59 > 0:45:05one another. There will be bits of food. It's not good. As soon as they
0:45:05 > 0:45:10k, they scramble up to the whole and stick -- hole and stick their heads
0:45:10 > 0:45:14out for fresh air. When they're making that hole, there's a lot of
0:45:14 > 0:45:19sawdust that comes out and they purposely push a little bit of it
0:45:19 > 0:45:24inside the hole to soak up any of the poo. Makes sense.Makes it a bit
0:45:24 > 0:45:29cleaner. I am sure it's pretty revolting. They've been busy today,
0:45:29 > 0:45:33the male and female have been in and out of here all day. In the
0:45:33 > 0:45:37summertime, although they're wood peckers, they sometimes spend less
0:45:37 > 0:45:43time pecking into wood, this is the male on his way out here, and more
0:45:43 > 0:45:48of the time using that bill as a sort of set of forceps to prize in
0:45:48 > 0:45:52and under the bark looking for insect larvae. There's the female
0:45:52 > 0:45:57that's gone in there as well. stunning bird to see. It's great
0:45:57 > 0:46:01when you see it on your bird feeders. Let's look at our bird
0:46:01 > 0:46:05feeders live. There's nothing going on there at the moment. A squirrel!
0:46:05 > 0:46:10At the bottom. You're unlikely to see birds at this time. There has
0:46:10 > 0:46:15been a lot of action on our live feeder cam and many of you have been
0:46:15 > 0:46:19enjoying that online and on the red button. There he is, the celebrity
0:46:19 > 0:46:24of the bird feeder. In tip top condition. Look how smart that bird
0:46:24 > 0:46:28is. You know, when those chicks hatch, they may well be brought to
0:46:28 > 0:46:36this feeder because that's what they do. They bring the chicks along. If
0:46:36 > 0:46:43you're lucky you might see some. These are siskins. There is a
0:46:43 > 0:46:50juvenile on the left making the most of that feeder. Then there we have a
0:46:50 > 0:46:55gold finch. Beautiful bird. Yeah. A bit overdressed. The thing is that
0:46:55 > 0:46:58bird may well be feeding on those seeds because they feed their young
0:46:58 > 0:47:03by regurgitation. It might be going back to its nest and regurgitating
0:47:03 > 0:47:08some of that food into the nestlings' mouths. Typically, at
0:47:08 > 0:47:12this time of the year, many birds won't be on the feeders they will be
0:47:12 > 0:47:16looking for insects. It's still important to feed any animals coming
0:47:16 > 0:47:20into the garden. There are tips on how to do that in our booklet, which
0:47:20 > 0:47:25you can download from our website. There's a link to that on our home
0:47:25 > 0:47:29page. Or collect one of these if you go to one of the many events that
0:47:29 > 0:47:33summer of wildlife are hosting. I'm in there and it's me giving the tips
0:47:33 > 0:47:37on how to feed your garden animals. You know what, it's not only a great
0:47:37 > 0:47:43thing to do for the wildlife, but it's a great way to learn more about
0:47:43 > 0:47:50wildlife in your garden. Fantastic. Outside your child's bedroom window,
0:47:50 > 0:47:57feeder, now or by Monday. Let's go live to our meadow pip its.
0:47:57 > 0:48:01Look at that. There are all the young punks in the nest. Look at
0:48:01 > 0:48:06those hair cuts. A bit sleepy at this time of day. They have been
0:48:06 > 0:48:10busy. The nest is in the open. They're very much a bird of open
0:48:10 > 0:48:20moorland. Here they are just one day old. Look at how quickly they've
0:48:20 > 0:48:25grown. Oh, my goodness.Look at that. It's very well hidden this
0:48:25 > 0:48:29nest and the adults approach it stealthily. They don't fly straight
0:48:29 > 0:48:34in giving the whereabouts away. They land on the ground some distance
0:48:34 > 0:48:39away and then walk to it. They've been bringing in a great range of
0:48:40 > 0:48:43invert brat prey to these animals. See the way it sneaks out there,
0:48:43 > 0:48:48they are tremendously well hidden. Another thing that's been well
0:48:48 > 0:48:52hidden simply because it's nocturnal are many of the mammals here. Martin
0:48:52 > 0:48:57has been trying to combat that elusive nature of these animals by
0:48:57 > 0:49:01setting up his camera traps. I have, but before I go any further,
0:49:01 > 0:49:05I've just heard a sound I haven't heard for years. There's a cook coo
0:49:05 > 0:49:10calling just over on the hills there.
0:49:10 > 0:49:15Wonderful place this. Yeah, you're right. We have lots of birds on
0:49:15 > 0:49:21Springwatch, but we try our hardest to bring you some mammals as well.
0:49:21 > 0:49:25To that end, I've been setting up mammal camera traps all around here.
0:49:25 > 0:49:33What is a camera trap? You probably have one at home. They're a little
0:49:33 > 0:49:39box with a camera in it and it's box with a camera in it and it's
0:49:39 > 0:49:43triggered when an animal passes by. Did we catch anything? I had high
0:49:43 > 0:49:48hopes. No. It's a blackbird. Now it's a thrush.
0:49:48 > 0:49:53Could we get a mammal? No, we got a Great Tit.
0:49:53 > 0:49:58At last, it's a mammal! It's a squirrel and he does another pass
0:49:58 > 0:50:03just running past us to show us how fast he can run. I was hoping for
0:50:03 > 0:50:09something more exciting, possibly something like this.
0:50:09 > 0:50:13Hares. We have hares here. What a fantastic animal. They're different
0:50:13 > 0:50:17from rabbits. Rabbits are social. They live in groups. Hares tend to
0:50:17 > 0:50:23be more solitary. They lie in a field. They make a depression,
0:50:23 > 0:50:30called a form, and they will stay in that during the day. They rely on
0:50:30 > 0:50:37eye sight. If a hare sees a threat and it can get up to speed, it can
0:50:37 > 0:50:42outroughen any British predator. -- out run any British predator.
0:50:42 > 0:50:47Another thing with hares, they have black tips to their ears and their
0:50:47 > 0:50:57tails are a bit black too. A rabbit has that white scutt that sticks
0:50:57 > 0:50:59
0:50:59 > 0:51:04out. Hares, beautiful things. Let us go immediately to the rodent -
0:51:04 > 0:51:08orium. There's nothing in there at the moment. We have seen action in
0:51:08 > 0:51:16there. Here is a scru. It's an insectivore but it should eat animal
0:51:16 > 0:51:21food but it's eating a nut. This is a shrew here and a mouse. The mouse
0:51:21 > 0:51:24is eating as it should be, nuts and things. Remember it's pitch black in
0:51:24 > 0:51:28there. They always seem to be squabbling over the food. They
0:51:28 > 0:51:34should just shake pause and agree to differ and have a good feed, both of
0:51:34 > 0:51:38them. Now lots of you have been, well not lots, some of you have been
0:51:38 > 0:51:43asking, OK it's all very well, but how do you tell the difference
0:51:43 > 0:51:49between mice, voles, shrews? What's an easy guide? Here's our simple
0:51:49 > 0:51:55guide to small mammals. Here is a vole. Quite small ears,
0:51:55 > 0:51:59quite little eyes and a short tail. On the left, that's a mouse, much
0:51:59 > 0:52:05bigger ears, sort of sticky out bulging eyes and a long tail and
0:52:05 > 0:52:12down at the bottom, that's a shrew. Quite different. It's got a great
0:52:12 > 0:52:15big, long snout sticking out. I used to trap them when I was at
0:52:15 > 0:52:20university and be aware that shrews bite like fury. Any way, from some
0:52:20 > 0:52:30very small animals, mammals to a very, very big wet mammal. Yes it's
0:52:30 > 0:52:34
0:52:34 > 0:52:39time to go back to the adventures in The busy port of Aberdeen never
0:52:39 > 0:52:43seems to sleep. So it's a real surprise to find a large population
0:52:43 > 0:52:47of dolphins seemingly thriving amongst all these ships. They've got
0:52:47 > 0:52:56the whole of our coastline to play with, so why are they hanging around
0:52:56 > 0:52:59here? We've got bottlenose dolphins in the heart of Aberdeen here.
0:52:59 > 0:53:04far I've had wonderful views. Wouldn't it be great to get that
0:53:04 > 0:53:14much closer to them to find out exactly what's going on. I've got a
0:53:14 > 0:53:23
0:53:23 > 0:53:27helicopter is fitted with a small camera, perfect for getting an
0:53:27 > 0:53:31aerial view of what's going on in the harbour. I can see everything
0:53:31 > 0:53:41that the camera can see on this monitor. It's superb. Absolutely
0:53:41 > 0:53:45superb. These dolphins are tough. They're used to riding shoulder to
0:53:45 > 0:53:49shoaled wear trawlers and container boats. Nevertheless, there's a good
0:53:49 > 0:53:56reason for using this kit. The big advantage of this is that it's
0:53:57 > 0:54:01small, fairly quiet and so it won't disturb the animals in any way. The
0:54:01 > 0:54:07helicopter gives me a great Birds Eye view of the harbour and it
0:54:07 > 0:54:09reveals that the dolphins are congregating in one particular area.
0:54:09 > 0:54:14From up here, the transition between the brown, fresh water that spills
0:54:14 > 0:54:18out of the River Dee and the blue of the North Sea is clearly visible.
0:54:18 > 0:54:26The dolphins seem to be focussing all their attention on this
0:54:26 > 0:54:34boundary. And this suggests they're here for one thing: It's the spring
0:54:34 > 0:54:39salmon run. At this time of year, the Scottish coast sees a huge rise
0:54:39 > 0:54:42in the numbers of Atlantic salmon. The salmon return from the open sea
0:54:42 > 0:54:52on an extraordinary journey, travelling up stream to spawn in the
0:54:52 > 0:54:56rivers of their birth. Scotland's bottlenose dolphins follow the great
0:54:56 > 0:54:59migration, hunting the salmon as they move down the coastline. In
0:54:59 > 0:55:02Aberdeen the salmon encounter a bottleneck. They must pass through
0:55:02 > 0:55:07the narrow mouth of the harbour before continuing their journey up
0:55:07 > 0:55:10the River Dee. The dolphins have learned that this
0:55:10 > 0:55:18harbour offers rich pickings and especially in spring. It's the
0:55:18 > 0:55:23migrating salmon that are drawing them in. Working in teams, the
0:55:23 > 0:55:27dolphins use the harbour walls to herd the salmon together. The
0:55:27 > 0:55:32junction between the fresh water and the sea acts like an additional
0:55:32 > 0:55:36barrier helping their echolocation to focus in on the fish. Tail slaps
0:55:36 > 0:55:43and jumps are thought to be used as a way of communicating hunting
0:55:43 > 0:55:53strategy. Aberdeen's dolphins are dapting to live with the noise and
0:55:53 > 0:55:58
0:55:58 > 0:56:02traffic of this busy harbour to make fact that the bottlenose dolphins
0:56:02 > 0:56:06aren't just doing well, they are thriving, despite all of these huge
0:56:06 > 0:56:12ships, the small boats, all the human activity, and for me, well,
0:56:13 > 0:56:22it's been a rare privilege to spend time close up and personal with
0:56:23 > 0:56:24
0:56:24 > 0:56:28dolphins in Aberdeen. It's not just us who can see them, you can as
0:56:28 > 0:56:32well. If you would like to do that, check out how you can do it and
0:56:32 > 0:56:36where around the coast on our website under "thingedz to do".
0:56:36 > 0:56:39That's part of summer in wildlife to encourage you to get out and enjoy
0:56:39 > 0:56:44what the Cannes trip has to offer. There let's look around the live
0:56:44 > 0:56:49cameras. First to our grasshopper warbler. We haven't seen this bird
0:56:49 > 0:56:53today. There, presumably, the female, brooding the young. It's
0:56:53 > 0:56:58beginning to get cooler here now. We've moved the camera so you can
0:56:58 > 0:57:01look out offer the nest and see out. Look at that. I think they're
0:57:01 > 0:57:06underrated as a bird. They might be small and brown, but they're
0:57:06 > 0:57:11delicately marked and with a great song. Now stonechats, let's see if
0:57:11 > 0:57:15she's brooding as well. Yes. Look at that. Lovely eye ring on that bird,
0:57:15 > 0:57:20the female brooding her chicks. Those are quite large chicks as
0:57:20 > 0:57:26well. She'll be keeping those on overnight. At night they all hunker
0:57:26 > 0:57:32down. They look so snuggly. They do. Here, the water rails there. She has
0:57:32 > 0:57:35just been off, still got eggs. Still eggs. Prediction wasn't that good
0:57:35 > 0:57:41then. Building up the nest. They've been doing that the whole time. The
0:57:41 > 0:57:46nest has been built up and up. Now to the great tits, live, because oh,
0:57:46 > 0:57:52no! They have fledged. It's happened! This is a crazy time of
0:57:52 > 0:57:55night for them to fledge. Is going night for them to fledge. Is going
0:57:55 > 0:58:03on. It's going to go!We're seeing them fledge live. I think we'll have
0:58:03 > 0:58:06to show this again tomorrow. There's only one left. Going to go.That was
0:58:06 > 0:58:14going to be our cliffhanger for tomorrow. It's happened. There will
0:58:14 > 0:58:22be a lot more of that tomorrow and, I'm really distracted. It's gone.
0:58:22 > 0:58:26It's gone. And catching up with the jackdaws as well. And with Kate, a
0:58:26 > 0:58:33lady following the antics in her garden in the last couple of years.
0:58:33 > 0:58:39She's attracting mammals now. We're featuring a film about nests where
0:58:39 > 0:58:44you get extraordinary mammals. back at the earlier time of 7. 30pm
0:58:44 > 0:58:47tomorrow and Unsprung at 8. 30pm. After that go over to the red button
