We are alive in Lancashire for the autumn season's greatest spectacles | :00:09. | :00:17. | |
- vast flocks of starlings. Stately stags strutting out of the reeds, | :00:18. | :00:25. | |
what could be finer? We will be back with you for the next four nights | :00:26. | :00:27. | |
bringing you the best of Autumnwatch. We have these little | :00:28. | :00:36. | |
rarities, there are only 20 pairs of them - you are excited, and you? | :00:37. | :00:43. | |
Fantastic. I am going to be out and about. I am going to go into the | :00:44. | :00:48. | |
darkness and become Autumnwatch's life roving reporter. What could | :00:49. | :00:52. | |
possibly go wrong? Welcome, it is Autumnwatch. | :00:53. | :01:19. | |
Hello, and welcome to Autumnwatch, coming to you life from the RSPB | :01:20. | :01:24. | |
reserve here in the north-west of England. It is a fabulous reserve. | :01:25. | :01:28. | |
This is how I see it, you come in from school or college or work, you | :01:29. | :01:33. | |
have had your dinner made a cup of tea, and have settled on the sofa, | :01:34. | :01:42. | |
and we aim to offer you a great escape from these damp and dark | :01:43. | :01:45. | |
nights and bring you the finest spectacles of autumn - a dynamic and | :01:46. | :01:51. | |
dramatic season. It is a season of change which offers naturalists days | :01:52. | :01:57. | |
of glory. It offers the white life time of make or break. We decided to | :01:58. | :02:01. | |
choose a theme for our programme this year. We have chosen a familiar | :02:02. | :02:08. | |
one, migration. We will look at why, where and when migration takes | :02:09. | :02:13. | |
place. We will not provide the answers. I like that, it means there | :02:14. | :02:20. | |
is more to learn. Migration holds a lot of mystery for us. This is the | :02:21. | :02:27. | |
perfect place, Leighton Moss RSPB reserve. There are lots of migrating | :02:28. | :02:31. | |
birds coming here. It may be a dynamic time, autumn, but it can | :02:32. | :02:37. | |
also be unpredictable. It was quite mild last week, and then yesterday, | :02:38. | :02:43. | |
St Jude the storm hit many parts of the UK. I think wiki skipped it here | :02:44. | :02:48. | |
in the north-west, but it had a devastating impact in parts of the | :02:49. | :02:52. | |
South of England. -- I think we escaped it. How did it affect our | :02:53. | :02:57. | |
wildlife? Especially migrating birds. For many of them, it stopped | :02:58. | :03:01. | |
migration, but for how long? That is one thing we will be looking at. We | :03:02. | :03:07. | |
will be looking at how it has had any lasting impact. Coming up, some | :03:08. | :03:13. | |
fantastic night-time footage of some of the creatures here on the | :03:14. | :03:19. | |
reserve, including otters. We have got some very interesting behaviour. | :03:20. | :03:23. | |
By using a brand-new, state-of-the-art thermal camera, we | :03:24. | :03:27. | |
have managed to get these images of animals like red deer and Fox. That | :03:28. | :03:38. | |
is in pitch blackness, and it is so clear. This is military grade and it | :03:39. | :03:44. | |
is a great opportunity to use a life for the first time. We're hoping for | :03:45. | :03:48. | |
not only great pictures, but things we have not spotted before. That | :03:49. | :03:51. | |
would be fantastic. Let's go to the camera so we can see what it has | :03:52. | :03:56. | |
got. That is a view over the reserve. The bird you can see | :03:57. | :04:03. | |
slumbering in the drizzle is a swan. It looks dark, because that | :04:04. | :04:08. | |
means it is cold. Dark means cold, white means warm. We will have to | :04:09. | :04:15. | |
remind people it is in darkness, it is hard to believe. It is raining! | :04:16. | :04:24. | |
Martin, have you got stuck in the mud? We are ready to go. Migration | :04:25. | :04:29. | |
is one of the key themes on Autumnwatch. Just earlier this week, | :04:30. | :04:35. | |
some 30,000 starlings arrived here on the reserve. We are going to go | :04:36. | :04:41. | |
out right now and find out why they are here and what they are up to | :04:42. | :04:48. | |
right now. See you later. He is hardly making a speedy | :04:49. | :04:52. | |
getaway, the right thing to do on a nature reserve in the dark. But what | :04:53. | :04:56. | |
about this place, what is it about and what lesser? Take a look. We | :04:57. | :05:03. | |
have come to Leighton Moss RSPB reserve on the wild Lancashire | :05:04. | :05:06. | |
coast, to be at the heart of the autumn action. It is nestled in the | :05:07. | :05:12. | |
Silverdale area of Outstanding Natural Beauty, and is near | :05:13. | :05:20. | |
Morecambe Bay, the second largest area of mudflats in the UK. It is a | :05:21. | :05:32. | |
magnet for hundreds and thousands of wildfowl flying in from all over the | :05:33. | :05:38. | |
North. Some come to feed in the S jury, while others seek the safety | :05:39. | :05:44. | |
of the reedbeds. -- some come to feed in Morecambe Bay. But it is not | :05:45. | :05:51. | |
just the birds who are attracted here. There is plenty of other white | :05:52. | :05:56. | |
life, too, and now is a fantastic time to see this autumn spectacle. | :05:57. | :05:58. | |
-- plenty of other wildlife. We will be delving further into the | :05:59. | :06:18. | |
lives of these animals as they faced the challenges of autumn and the | :06:19. | :06:24. | |
coming winter. Leighton Moss is going to be our home for this series | :06:25. | :06:28. | |
of Autumnwatch. This is where we are going to shelter from the rain, this | :06:29. | :06:34. | |
fabulous barn. It is on a working farm not far from the reedbeds. We | :06:35. | :06:38. | |
have put some Autumnwatch magic in here, it has had a make over. We | :06:39. | :06:46. | |
have got our sofas, lots of autumn decor. It does look a bit rustic. | :06:47. | :06:57. | |
Where are we? Here is a map of the UK. We are up in the north-east. | :06:58. | :07:06. | |
This is the Lake District above us and this is Morecambe Bay. We are in | :07:07. | :07:12. | |
the north-west, sorry. Morecambe Bay is 340 square kilometres of | :07:13. | :07:16. | |
mudflats. The reserve is over here at Leighton Moss. We have 23 square | :07:17. | :07:28. | |
calamities of RSPB reserve, ten kilometres of which are reedbeds. It | :07:29. | :07:33. | |
has made this a Site Of Special Scientific Interest and it is not to | :07:34. | :07:42. | |
scale, but this is where we are. This is the causeway, where Martin | :07:43. | :07:47. | |
will be exploring the wetland area. This is the cafe, where 100,000 | :07:48. | :07:54. | |
visitors a year pop in for some cake. I have to say, the staff | :07:55. | :08:05. | |
working in the cafe should be contenders for Great British Beg Off | :08:06. | :08:15. | |
-- Bake Off. Have you had the cake? I have. It is not just around the | :08:16. | :08:23. | |
reserve we have had cameras, but on Morecambe Bay in itself. It is a | :08:24. | :08:31. | |
fabulous place for wading birds. You have got the charismatic | :08:32. | :08:33. | |
oystercatcher and lots of migrant birds coming in as well. Why do they | :08:34. | :08:41. | |
come? For the mud. It is full of nutrients and we are going to be | :08:42. | :08:44. | |
taking a much closer look at that during the week. The beauty of | :08:45. | :08:49. | |
having these roving cameras and remote cameras is that you never | :08:50. | :08:54. | |
know what we will get. Last night we got this gem. Very interesting | :08:55. | :09:02. | |
behaviour from some arteries. -- otters. This is a young otter | :09:03. | :09:08. | |
minding its own business. Suddenly, it sees something and look around. | :09:09. | :09:18. | |
It starts calling. That is much bigger otter, giving it whack around | :09:19. | :09:31. | |
the face with its tail. It is like a dinosaur with a club on its tail, | :09:32. | :09:39. | |
that is what this otter is doing. But we suspect that is its father, | :09:40. | :09:42. | |
because if it was not it would be a bigger fight. This is likely this is | :09:43. | :09:50. | |
one of his last set of cards. Just look at the whiskers! This camera is | :09:51. | :09:59. | |
giving us interesting behaviour. So often you see otters sliding in and | :10:00. | :10:03. | |
out of the water. Then, something else happens. We see this beautiful | :10:04. | :10:13. | |
red deer stag on the bank. We will be looking at that more closely | :10:14. | :10:17. | |
tomorrow. We will bring you plenty more. What about migration itself? | :10:18. | :10:25. | |
Already, the reserve has had its numbers swollen by starlings. These | :10:26. | :10:28. | |
birds have come in from Scandinavia as it is beginning to get cold. Here | :10:29. | :10:33. | |
they are, lined up in their spotted winter coats. We think that | :10:34. | :10:39. | |
thousands of these birds arrived at Leighton Moss to provide quite a | :10:40. | :10:44. | |
spectacle. Martin has gone out to find out why they have come to the | :10:45. | :10:55. | |
reserve, and why now? To start to answer that, I have come down here | :10:56. | :11:00. | |
into the heart of the reserve. I am driving along this central road. We | :11:01. | :11:08. | |
are in the heart of the reedbeds. There is about ten square | :11:09. | :11:11. | |
kilometres, it is the biggest in the whole of the North West. This is the | :11:12. | :11:15. | |
secret to fry the starlings come here. The reeds are just outside the | :11:16. | :11:24. | |
car. They are tall and strong. That is why they have come down, there is | :11:25. | :11:29. | |
a safe refuge. A few days ago, I was lucky enough to go out and watch | :11:30. | :11:32. | |
what happened when the starlings come into these reedbeds. There is a | :11:33. | :11:56. | |
whole language around these Murray shins -- murmurations. They are | :11:57. | :11:59. | |
showing the other starlings, come to us. It is exciting watching them | :12:00. | :12:10. | |
coming in in dribs and drabs and then gradually filling out. It is | :12:11. | :12:12. | |
almost like smoke. Positively biblical. You can argue | :12:13. | :12:43. | |
that this if you like, but surely this has to be one of our greatest | :12:44. | :12:47. | |
British wildlife spectacles? I never, ever get tired of seeing | :12:48. | :13:35. | |
this. When they do drop Ben, they go | :13:36. | :13:58. | |
remarkably quickly. Once they have made the decision to rock in... Here | :13:59. | :14:00. | |
they come! Look at that! What a fantastic site that is. You | :14:01. | :14:33. | |
never get bored of seeing that. That raises a question - we have just | :14:34. | :14:37. | |
said that there are ten square kilometres here of reedbeds. Let's | :14:38. | :14:44. | |
walk amongst them. Oh, my Lord! It is very boggy. With ten square | :14:45. | :14:51. | |
kilometres, wide of the starlings, all 30,000, pouring too one small | :14:52. | :14:59. | |
area? If it was about ten foot wide, you could have hundreds of | :15:00. | :15:06. | |
starlings. Why do they do it? There is safety to numbers if they stick | :15:07. | :15:10. | |
together. What would happen if a predator came along and came amongst | :15:11. | :15:17. | |
the starlings flop? -- starling flock. Here is a marsh harrier | :15:18. | :15:24. | |
flying in. What will happen when it hits the flock of starlings? Here it | :15:25. | :15:25. | |
comes in amongst them safe from aerial predators, but look | :15:26. | :16:07. | |
at this. I am sinking in a bit! If you were a fox or a weasel or stoat, | :16:08. | :16:10. | |
would you want to come hunting in this? You wouldn't. It is a good | :16:11. | :16:16. | |
place for all those darlings to be. It is also a good place for | :16:17. | :16:22. | |
different animals, something really surprising. There are enormous red | :16:23. | :16:31. | |
deer here. There is a gigantic stab we will be following -- stag. We are | :16:32. | :16:52. | |
not quite sure what is going on. It is only coming into season for a | :16:53. | :16:55. | |
short period, he will have to look after them and be around them all | :16:56. | :17:00. | |
the time. We will keep following them. | :17:01. | :17:06. | |
We have got lights on here all around me. Let us turn the lights | :17:07. | :17:09. | |
off and find out what it is really like in the reedbeds. And my head | :17:10. | :17:16. | |
torch, I cannot find the switch exhibition mark it is completely | :17:17. | :17:21. | |
dark. This is what it would be like in the starling colony. With this | :17:22. | :17:28. | |
special camera we can look into the heart of the colony and see what is | :17:29. | :17:36. | |
going on. Look at this. Here are all the starlings, this was | :17:37. | :17:40. | |
a shock and surprise. We thought they all went in and settled down | :17:41. | :17:45. | |
and went to sleep. But they are not doing that, they are moving around. | :17:46. | :17:50. | |
The cameraman filmed this about midnight and they were still moving | :17:51. | :17:55. | |
around. It is pitch black, they are not clearly moving around very | :17:56. | :17:59. | |
accurately, they are bumping into each other. That camera will reveal | :18:00. | :18:04. | |
more and more about the curious things going on at night here at | :18:05. | :18:09. | |
Leighton Moss. Now, migration. What makes all of | :18:10. | :18:14. | |
these words move from one part of the planet and another? It comes | :18:15. | :18:19. | |
down to planetary astronomical physics. Could you be the son, | :18:20. | :18:35. | |
these? -- the Sun, please? Our planet spins on an axis like this | :18:36. | :18:39. | |
which gives us day and night. It also orbits the Sun, taking a year | :18:40. | :18:49. | |
to do so. It doesn't do that on a vertical axis, it is off-kilter by | :18:50. | :18:56. | |
23.5 degrees. The obliquity of the ecliptic. When the sun Acrobat Earth | :18:57. | :19:02. | |
is in an area like this and moves round, the UK and Europe would be | :19:03. | :19:09. | |
closer to the sun, it is not the distance, it is the incidence of the | :19:10. | :19:14. | |
light rays passing through the atmosphere and the day length. Nice | :19:15. | :19:19. | |
long days warming up the ground means a nice summer. When we reach | :19:20. | :19:24. | |
this side of the Sun we are tilted away from it, shorter days, less | :19:25. | :19:31. | |
time to warm the environment up and in the northern part of the region | :19:32. | :19:35. | |
we have our winter. As a consequence, if animals can move | :19:36. | :19:39. | |
they will do their very best to get out of the way and move further | :19:40. | :19:43. | |
south where it should be warmer and easier for them to survive will stop | :19:44. | :19:49. | |
is it break time now? Is that the end of the geography lesson? | :19:50. | :19:53. | |
Migration is a fascinating subject and the ability of animals to travel | :19:54. | :19:58. | |
huge distances every year never ceases to amaze. This time of year | :19:59. | :20:05. | |
so many species are on the move. Migration. | :20:06. | :20:11. | |
Every autumn billions of animals traverse the globe. The British | :20:12. | :20:19. | |
Isles are the epicentre for an astonishing number of migratory | :20:20. | :20:28. | |
species. From our smallest, to our largest. Migration has always | :20:29. | :20:37. | |
fascinated us. 2000 years ago Aristotle noticed the sudden | :20:38. | :20:46. | |
disappearance of birds from ancient Greece and believed they had | :20:47. | :20:50. | |
transmuted into Robins. We believed 250 years ago when autumn came | :20:51. | :20:56. | |
swallows hibernated at the bottom of legs. Now with advancing technology | :20:57. | :21:06. | |
we can follow where our migrants are coming from and going. GPS, radar, | :21:07. | :21:11. | |
with these we have trapped Arctic turns, 25,000 miles from pole to | :21:12. | :21:17. | |
pole. We have followed ospreys on the long pilgrimage from Wales to | :21:18. | :21:24. | |
west Africa. And we have monitored British basking sharks which turn up | :21:25. | :21:31. | |
in the Canary Islands. Even leatherback turtles across the | :21:32. | :21:34. | |
Atlantic can get to Britain, all the way from the Caribbean. Our | :21:35. | :21:39. | |
incredible migrants represent written all over the world. Some | :21:40. | :21:45. | |
follow the stars and the sun, some follow landmarks, others follow | :21:46. | :21:50. | |
their nose, literally smelling their way home. Our understanding of | :21:51. | :22:02. | |
migration has come a long way. The UK's unique global permission -- | :22:03. | :22:07. | |
position gives us a front row seat for the most spectacular event. | :22:08. | :22:17. | |
All of those animals are on the move, but why are so many of them | :22:18. | :22:22. | |
interested in coming to the UK? Look at this. This map shows isobars. | :22:23. | :22:27. | |
They are lines across the map which indicate temperature. Isotherm is. | :22:28. | :22:34. | |
They indicate the average temperature during January. Look up | :22:35. | :22:44. | |
into Russia. Here it is ice cold. In Alexandria in Egypt's it is much | :22:45. | :22:49. | |
warmer. You might expect that because of Latitude. But the lines | :22:50. | :22:53. | |
are not straight, they wriggle around the UK. Indicating that here | :22:54. | :23:00. | |
to the left of the UK it is higher than zero degrees throughout | :23:01. | :23:05. | |
January. We are caught in this warm pocket. Why? It comes down to the | :23:06. | :23:11. | |
Gulf stream which comes up through here, arches up towards Iceland and | :23:12. | :23:16. | |
sweeps down the North Atlantic past Ireland. This maritime warmth heats | :23:17. | :23:23. | |
up the UK and makes it a very attractive destination for migrants, | :23:24. | :23:26. | |
the titular Lee from those coming from this direction, from the east | :23:27. | :23:32. | |
where it is considerably colder. But the storm this week changed that, | :23:33. | :23:38. | |
and things were far from all quiet on the Western front and we have had | :23:39. | :23:42. | |
birds blowing in from the Americas. We have had a yellow-rumped | :23:43. | :23:48. | |
warbler, this has turned up in Devon. We are interested in | :23:49. | :23:55. | |
migration we can all see. We will launch what we will call our | :23:56. | :24:00. | |
migration watch in conjunction with the RSPB and we want you to look out | :24:01. | :24:04. | |
for three particular birds. The first is the Redwing. It is easy to | :24:05. | :24:10. | |
identify, a member of the thrush family. You can see it's distinctive | :24:11. | :24:15. | |
eye stripe. They will come into your garden is to feed on berries. They | :24:16. | :24:20. | |
have a very characteristic call. It is the high-pitched sleep. -- -- | :24:21. | :24:37. | |
seep. You need to go out at night, stand on the doorstep and listen. | :24:38. | :24:41. | |
They will move about night. It is a characteristic call. The next word | :24:42. | :24:53. | |
is that brambling. The colouring is quite different, that was a male. It | :24:54. | :25:03. | |
had an orange chest. The last bird is this beauty. It is the waxwing. | :25:04. | :25:14. | |
This winter there might be a few number. Some have arrived already, | :25:15. | :25:20. | |
mainly in the north-east. We would like you to look out for these | :25:21. | :25:26. | |
birds. If you see any of these three species let us know on the website. | :25:27. | :25:40. | |
Let us know if you find them. I think waxwing is my favourite. Those | :25:41. | :25:49. | |
birds are just arriving in the UK but some of the birds that bred here | :25:50. | :25:53. | |
in the spring have moved on including one of our stars from | :25:54. | :25:57. | |
previous programmes, Monty, the osprey. He arrived in Wales on his | :25:58. | :26:07. | |
own, but not for long. That was one of the many females trying to | :26:08. | :26:11. | |
attract his attention. They were fighting over him. In the end and | :26:12. | :26:17. | |
inexperienced first time reader caught his affections. -- breeder. | :26:18. | :26:24. | |
They laid their eggs late and left them unattended which meant they | :26:25. | :26:27. | |
were prone to attacks from birds like Luke Rowe there. Were they | :26:28. | :26:34. | |
doomed? What has happened since then? | :26:35. | :26:40. | |
Monty was up against it. Osprey normally hatch after 37 days but | :26:41. | :26:49. | |
still nothing. On the 27th of June the 1st hatchling on a female. Two | :26:50. | :26:54. | |
days later another. The chicks grew fast. Dad was | :26:55. | :27:07. | |
bringing home 30 fish every week, they quickly put on weight. After | :27:08. | :27:21. | |
five weeks the chicks were mature enough to be monitored by staff and | :27:22. | :27:25. | |
the two girls were named. With two beautiful chicks to raise | :27:26. | :27:41. | |
they were busier than ever. Dad kept the fish flowing. But what is so | :27:42. | :27:52. | |
alluring about his legs? The family repelled intruders flying overhead, | :27:53. | :27:56. | |
already on their way back to Africa. The constant reminder of how | :27:57. | :27:59. | |
behind they were in their development. But on the whole, life | :28:00. | :28:05. | |
was good. The fledgling 's were now feeding themselves, giving Monty a | :28:06. | :28:11. | |
well earned rest. He was close to notching up 500 fish this season. | :28:12. | :28:15. | |
Though he could still use a lesson in presentation. The chicks | :28:16. | :28:24. | |
new-found independence was the mother 's cue to leave. She began | :28:25. | :28:30. | |
her long journey to Senegal on the 31st of August. It was all down to | :28:31. | :28:37. | |
Monty now. He kept his girls fed for a few more weeks. By now other | :28:38. | :28:43. | |
British ospreys were already basking in the hot African Sun but as long | :28:44. | :28:48. | |
as his daughters still needed him he resisted the urge to leave. Finally, | :28:49. | :28:57. | |
on the 18th of September, the mother began her first ever migration to | :28:58. | :29:03. | |
West Africa. Two days later, the second made her move. Then dad | :29:04. | :29:10. | |
followed, 36 minutes behind. Who knows when they will be back? But | :29:11. | :29:17. | |
for now Monty's work was done. Two eggs, two girls, hatched two days | :29:18. | :29:21. | |
apart and now on their migration. Also two days apart. What an | :29:22. | :29:27. | |
incredible summer for Monty, and what an amazing, handsome dad. | :29:28. | :29:35. | |
He has got all the characteristics I like in Amman. -- in a male. Spiky | :29:36. | :29:43. | |
haired, bulging eyes, bloke who goes fishing the whole time. When you put | :29:44. | :29:50. | |
it like that! He is patient, attentive, he is a good father. He | :29:51. | :29:56. | |
flies off all winter. He has gone 3000 miles, to Senegal. Hopefully. | :29:57. | :30:04. | |
Why has he gone there? There is plenty of fish and plenty of | :30:05. | :30:12. | |
sunshine. The Gambia cub River runs down there and there are wonderful | :30:13. | :30:18. | |
wetlands. -- the Gambia River. We hope that Monty will come back. We | :30:19. | :30:25. | |
have had birds moving cells, but they have stopped with us. One group | :30:26. | :30:40. | |
which have either starlings. -- which have all the starlings. I can | :30:41. | :30:44. | |
hear all of the sounds of the waterfowl. We have found out why the | :30:45. | :30:54. | |
starlings come here. It is safety. Let's look at these reeds. These | :30:55. | :31:02. | |
leaves are quite flexible. When the wind blows, all of the leaves | :31:03. | :31:12. | |
line-up. It can bend around, but they do not break. The starlings are | :31:13. | :31:32. | |
able to roost on the same stem. There is a hierarchy. If you are at | :31:33. | :31:44. | |
the bottom, you will get pooed on. This is the colony. The black bits | :31:45. | :31:56. | |
are the starlings. The best place to be as high up but in the middle. The | :31:57. | :32:00. | |
most dominant birds will go there. They will squabble and fight. One of | :32:01. | :32:09. | |
the other advantages about being in the middle is that you keep warm. | :32:10. | :32:14. | |
You can see them fluffing up their feathers. A starling is six degrees | :32:15. | :32:24. | |
warmer than we are in body cabbage. That is the perfect place, in the | :32:25. | :32:32. | |
middle. Beautiful pictures in the heart of the roost. That is about | :32:33. | :32:38. | |
half a kilometre away. They are fairly safe, but not always. | :32:39. | :32:45. | |
Sometimes, predators will be on the prowl at night. We have filmed a | :32:46. | :32:50. | |
specialist night predator. It is a barn owl. Do you see that? He has | :32:51. | :33:01. | |
dropped a starling. The barn owl was coming in. It has learned how to | :33:02. | :33:14. | |
take the starlings. If you have got 30,000 small packages of meat, if | :33:15. | :33:18. | |
you can take advantage of it, you will. We know that they are | :33:19. | :33:25. | |
successful, because the RSPB has found these remains. Tragically, | :33:26. | :33:34. | |
those are starling skulls from inside the nest box of the barn owl. | :33:35. | :33:40. | |
Their pellets are full of nothing but starlings. These clever barn owl | :33:41. | :33:46. | |
's have adapted to the starlings. -- these clever barn owls. You to full | :33:47. | :33:59. | |
little birds. -- beautiful little birds. To appreciate the beauty of | :34:00. | :34:06. | |
the individual bird, we need to see one close-up. It would be handy if | :34:07. | :34:17. | |
we had one. We have! This is a bird that many people take for granted. | :34:18. | :34:22. | |
Look at those feathers, they are beautiful. They are stunning. Those | :34:23. | :34:27. | |
feathers have an important purpose. They malted in the autumn, so they | :34:28. | :34:31. | |
have a fresh coat of feathers to keep them warm. -- moulted. The | :34:32. | :34:42. | |
inner core of a starling's body only fluctuates by about four back | :34:43. | :34:49. | |
degrees -- four degrees during the day. They also employ other means of | :34:50. | :34:53. | |
containing body heat. Then what keeps their feet warm? May use a | :34:54. | :35:04. | |
counter current heat exchanger. -- they use. As the warm blood is | :35:05. | :35:09. | |
pumped down from their body and the warm blood goes back into it, it's | :35:10. | :35:15. | |
what's the heat, so they do not lose body heat. # it exchanges the heat. | :35:16. | :35:22. | |
They have what we call a high surface area to volume ratio. They | :35:23. | :35:26. | |
would be prone to losing lots of heat. These are trained birds. Lloyd | :35:27. | :35:41. | |
will be stuck around for Autumnwatch Unsprung on the red button and | :35:42. | :35:47. | |
online after the programme. To really appreciate wildlife, you have | :35:48. | :35:50. | |
to get out there and see it for rail. We came up with an idea which | :35:51. | :35:59. | |
made us have a closer look at the wildlife and plants. We had a | :36:00. | :36:06. | |
friendly but rather competitive Autumnwatch Challenge. Your | :36:07. | :36:14. | |
challenge is to find a plant, animal or part thereof beginning with each | :36:15. | :36:19. | |
letter of the word Autumnwatch, and hopefully take a photo or film it. I | :36:20. | :36:24. | |
am going to sit in the cafe and sit for 45 minutes and have hot | :36:25. | :36:31. | |
chocolate. Let's get going and let them talk. Where is the cafe? C, | :36:32. | :37:03. | |
cake! That is a silver moth. The Latin name begins with A. What a | :37:04. | :37:15. | |
place. This is five minutes from where we started. Look at all of | :37:16. | :37:26. | |
these limestone pavements. Some of these are 2000 years old. They | :37:27. | :37:34. | |
reckon some of them could be 5000 years old. That is a fantastic piece | :37:35. | :37:44. | |
of sculpture. The scientific name starts with T. Shall I take a photo? | :37:45. | :37:59. | |
It could really be useful if we could spell! Are there any older | :38:00. | :38:14. | |
trees? -- alder. No, we are not going to cheat and use T for trees. | :38:15. | :38:25. | |
There should be an award for quality of species. They will come up with | :38:26. | :38:34. | |
lots of Latin names. But we have got Latin names, too. Look at this, | :38:35. | :38:57. | |
hart's tongue. That is no good, it run away! The Latin name for | :38:58. | :39:16. | |
stinging nettle is urtica. This is like the cover of that Nik Kershaw | :39:17. | :39:26. | |
album. That is not in my collection. It was like this, only in black and | :39:27. | :39:41. | |
white. Woodlouse, perfect for W. It is the only type of crustacean that | :39:42. | :39:57. | |
does not need water to breed. We need A, M and two Us. Look at this | :39:58. | :40:16. | |
day? -- look at this algae. I do not like using Latin, but, some of these | :40:17. | :40:32. | |
are useful. This is Cal Parsley --, parsley, umbellifer. We are being | :40:33. | :41:07. | |
beaten by two Us. Sorted! Brilliant. I never saw you as a Nik Kershaw | :41:08. | :41:12. | |
fan. I do not know much about him. My sister had a magazine on the | :41:13. | :41:16. | |
sideboard one day and I happened to glance at it as I was walking past. | :41:17. | :41:24. | |
I like to give credit where it is due. We did win the challenge. , | :41:25. | :41:39. | |
on, -- come on, we had two ewes. This again due can do your | :41:40. | :41:42. | |
Autumnwatch Challenge. You can use any word you like. -- this weekend, | :41:43. | :41:54. | |
you can do the Autumnwatch Challenge. Cheat if you cannot win! | :41:55. | :42:03. | |
Lots of you got out in the summer. Many of you joined the BBC's Summer | :42:04. | :42:14. | |
Of Wildlife Season. 46,000 of you did the Big Butterfly Count. We had | :42:15. | :42:21. | |
some amazing results. 46,000 people, 830,000 butterflies. We learned a | :42:22. | :42:27. | |
lot. The small tortiseshell, a species which has been struggling, | :42:28. | :42:34. | |
this summer it increased by 388%. Its close relative, the peacock, by | :42:35. | :42:40. | |
3500%. It shows you what you can do if you take part. Please get | :42:41. | :42:47. | |
involved. The storm, if you live in the South of England, has blown | :42:48. | :42:50. | |
loads of leaves of the trees but gardeners, do not rush out and sweep | :42:51. | :42:55. | |
them up. It would be pointless, there is more to come down and also, | :42:56. | :42:59. | |
they feed an army of amazing invertebrates. | :43:00. | :43:06. | |
Earthworms may be simple creatures, but they are pretty amazing. Living | :43:07. | :43:13. | |
a largely subterranean lifestyle, they have no need of eyes or ears | :43:14. | :43:19. | |
and rely on touch and taste to detect their world. They belong to a | :43:20. | :43:35. | |
group which translated means, little rings. Each of their segments is | :43:36. | :43:42. | |
encircled by muscle. These contract and relax in a concertina with, | :43:43. | :43:49. | |
propelling the animal foreword. In this way, the earthworm can achieve | :43:50. | :43:53. | |
top speeds. They can get up to 20 metres per hour! Earthworms are the | :43:54. | :44:04. | |
world's recycling heroes. They are biological re-processors that | :44:05. | :44:06. | |
transform dead plant matter into fertile humus. You can see soil | :44:07. | :44:14. | |
being created as it moves through the earthworm's body. When it comes | :44:15. | :44:18. | |
out the other end, the plant debris has become earth, enriched with | :44:19. | :44:30. | |
nutrients. They have been described as the intestine is of the soil. -- | :44:31. | :44:38. | |
intestines of the soil. There is an abundance in autumn of plant | :44:39. | :44:48. | |
material for them to recycle. They have a specially adapted prehensile | :44:49. | :44:52. | |
head. They use this flexible appendage like a hand will stop -- | :44:53. | :45:01. | |
like a hand. They drag leads into the ground to enable them to feed in | :45:02. | :45:08. | |
safety. By pulling the leaf at its tip the worm ensures it folds neatly | :45:09. | :45:17. | |
as it enters the soil. Underground the worm becomes a biological | :45:18. | :45:24. | |
piston. It forces life-giving air through the earth as it moves | :45:25. | :45:25. | |
creating tunnels as it goes. In one acre of woodland there may be | :45:26. | :45:39. | |
as many as 1 million worms, eating ten tonnes of leaves on the stems | :45:40. | :45:44. | |
and dead beats each year, and turning over 40 tonnes of soil. | :45:45. | :45:52. | |
Their industry will bury the majority of leaves that fall each | :45:53. | :45:56. | |
autumn and they replenish the soil with vital nutrients and in short | :45:57. | :46:02. | |
dead leaves don't go to waste. I give you the earthworm, the world 's | :46:03. | :46:07. | |
busiest recycler. Great recyclers, but with millions | :46:08. | :46:16. | |
of them in one a go, important in lots of food chains. The thrush, | :46:17. | :46:22. | |
blackbirds, dragging them out of the soil, they provide food for lots of | :46:23. | :46:26. | |
other animals. The Deer Hunter returns. That vehicle is packed with | :46:27. | :46:31. | |
electronic equipment. The sign came up saying key battery low, I thought | :46:32. | :46:39. | |
it was going to break down! Let's go live to our thermal camera. This is | :46:40. | :46:47. | |
a cormorant roost, we will be looking at it later. Those are all, | :46:48. | :47:04. | |
rents. -- Conrads -- cormorants. We have been watching another animal | :47:05. | :47:08. | |
out and about, it is this one, the badger. As you can see, they are | :47:09. | :47:13. | |
collecting leaflet, they are taking it down into their badger sets to | :47:14. | :47:21. | |
use it as bedding. -- they are collecting leaf litter. Talking of | :47:22. | :47:29. | |
badgers, I am sure it hasn't escaped your attention they remain in the | :47:30. | :47:33. | |
news. The debate continues about badges in the countryside. Many | :47:34. | :47:38. | |
people are still confused about what the problem actually is. What is it | :47:39. | :47:44. | |
about their biology, history and ecology that has got them into so | :47:45. | :47:48. | |
much trouble with humans? Martin went to Gloucestershire to see if he | :47:49. | :47:56. | |
could get some clarity. Badges of the UK's largest member of the | :47:57. | :48:03. | |
weasel family. They have roamed our landscape for half a million years, | :48:04. | :48:07. | |
living underground in a large family groups, heading out into the wilds | :48:08. | :48:13. | |
to forage. They eat everything from berries to birds eggs. These days | :48:14. | :48:18. | |
they rely mainly on earthworms. Places like rural Gloucestershire | :48:19. | :48:26. | |
with damp, fertile soil are ideal. From a badger macro was pointed view | :48:27. | :48:32. | |
this patchwork of fields and trees was perfect. -- from a badger's | :48:33. | :48:40. | |
point of view. The soil in the woods is soft enough for them to tunnel | :48:41. | :48:43. | |
into and make their underground homes. In fact, this area and others | :48:44. | :48:49. | |
like it in the south-west are so good there are more badgers here | :48:50. | :49:00. | |
than anywhere else. They are secretive, nocturnal creatures, you | :49:01. | :49:05. | |
would hardly know they were there. If you look closely their signs are | :49:06. | :49:12. | |
everywhere. I can see here badgers famed for their cleanliness and they | :49:13. | :49:14. | |
will drag out the bedding, take it out, let it dry out, and drag it | :49:15. | :49:22. | |
back down and have somewhere lovely to snuggle up and sleep. They don't | :49:23. | :49:28. | |
poo inside the set, they make a latrine. What is fascinating is you | :49:29. | :49:36. | |
can see it is full of bits of Apple. There has been a bumper apple crop. | :49:37. | :49:41. | |
They do eat a wide variety of things, but it is a carnival and | :49:42. | :49:46. | |
they have got the teeth and jaws to go with that -- carnivore. | :49:47. | :49:54. | |
It was their feisty nature and formidable armoury that first got | :49:55. | :50:01. | |
them into trouble with humans. In the past they were considered good | :50:02. | :50:07. | |
sport by some, an activity known as badger baiting. Patrick Bach is a | :50:08. | :50:13. | |
journalist and author who has spent years researching our changing | :50:14. | :50:19. | |
attitudes. Although it has been persecuted it was never classified | :50:20. | :50:25. | |
as a beast like or dear, why is that? Digging a badger from its home | :50:26. | :50:34. | |
was hard work so they were left alone. But whole villages went in | :50:35. | :50:39. | |
pursuit. It was a sport for working people, they would dig them up and | :50:40. | :50:43. | |
take them to the backyard of a pub, keep them alive for a couple of | :50:44. | :50:46. | |
months, bring it out of its box every night and set a different dog | :50:47. | :50:53. | |
against it and place bets on it. The verb to badger comes from our | :50:54. | :50:58. | |
relentless pursuit of this animal. Badger baiting was still a big thing | :50:59. | :51:02. | |
in the 60s and 70s. My grammar started watching them in the 1960s | :51:03. | :51:11. | |
-- my grandma. Only one of those was still occupied in 1973, all the rest | :51:12. | :51:18. | |
had been destroyed. It's ecology, its ability to fight, had got it | :51:19. | :51:22. | |
into trouble. Following a public outcry they were given legal | :51:23. | :51:29. | |
protection in 1973. As a result the UK became a much better place for | :51:30. | :51:34. | |
them, and their population rose. As we farmed cows, more and more | :51:35. | :51:40. | |
efficiently, creating short grass pasture, full of earthworms, we were | :51:41. | :51:43. | |
inadvertently farming badges as well. -- badgers. But then they came | :51:44. | :51:50. | |
into contact with a new threat, ovine to about Ulysses. -- bovine | :51:51. | :51:58. | |
debate Ulysses. Although it originated in cattle in 1971 badger | :51:59. | :52:03. | |
was discovered to be infected with it. Imagine I am a badger, this | :52:04. | :52:10. | |
would be a perfect place to find my favourite food, earthworms. It is | :52:11. | :52:14. | |
also where cattle like to graze. If a cow had bovine TB it might be | :52:15. | :52:19. | |
shedding the bacteria in its done, so either, and that would go into | :52:20. | :52:26. | |
the ground and bacteria can survive for weeks, months. They are bound to | :52:27. | :52:31. | |
come into contact with the badger. Their close oximetry -- close | :52:32. | :52:39. | |
proximity. Cattle found to be infected are slaughtered but once | :52:40. | :52:45. | |
bovine TB spreads into the wildlife population it is difficult to | :52:46. | :52:50. | |
control. An infected badger can pass the disease on to other animals, or | :52:51. | :52:55. | |
spread the bacteria over the past year once again, reinvent timber | :52:56. | :53:02. | |
cattle. Badgers are not the only carriers Ahmed dear -- the only | :53:03. | :53:10. | |
characters, but they are believed to be the major wildlife carrier back | :53:11. | :53:18. | |
to cattle. This is how badgers, by simply going about their daily | :53:19. | :53:22. | |
lives, once more have walked into trouble with humans. I wonder if any | :53:23. | :53:29. | |
animal has divided the British public as much as the badger does | :53:30. | :53:34. | |
today. Wildlife enthusiast are fascinated by them, captivated by | :53:35. | :53:41. | |
even a glimpse. But for others they are a threat to their livelihood, a | :53:42. | :53:45. | |
carrier of disease, little more than vermin. And yet they carry on doing | :53:46. | :53:51. | |
what they have done for tens of thousands of years, completely | :53:52. | :53:56. | |
unaware they have stepped right into the firing line. | :53:57. | :54:03. | |
They really are still in the firing line in Gloucestershire and Somerset | :54:04. | :54:10. | |
at the moment. It is a very emotive issue, very complicated, but if you | :54:11. | :54:14. | |
would like to know more about the science or see the debate from both | :54:15. | :54:18. | |
sides of the argument, or join in the debate and letters know your | :54:19. | :54:22. | |
opinion, go to the website. -- let us know. It is also the place to go | :54:23. | :54:29. | |
for other things, keeping an eye on the website and the social media is | :54:30. | :54:36. | |
a special member of the team. You are not just here for the website, | :54:37. | :54:41. | |
you are here for something else. I am presenting Autumnwatch Unsprung. | :54:42. | :54:44. | |
Loads of good stuff coming in already. Keep sending in your | :54:45. | :54:50. | |
images. Fantastic bit of murmuration art, the starlings are the big thing | :54:51. | :54:54. | |
at the moment. This is from Kenneth Barker. It looks like a bird. That | :54:55. | :55:06. | |
is fantastic. Have you got any murmurations that look like any | :55:07. | :55:12. | |
other creature? You are doing Autumnwatch Unsprung straight after | :55:13. | :55:14. | |
the show on the red button and online. Lots of ideas on what to do | :55:15. | :55:20. | |
if you get out and about. You will want to know what the weather is | :55:21. | :55:22. | |
like. The storm has been and gone, but it | :55:23. | :55:35. | |
was an extreme event. Symptomatic of what has been an energetic spell of | :55:36. | :55:42. | |
weather in the atmosphere. Mutually cheaply -- the very disturbed | :55:43. | :55:45. | |
atmosphere. Relatively mild conditions. Over the next few days | :55:46. | :55:51. | |
not as mild as it has been. Colder air coming from the north. Enough to | :55:52. | :55:56. | |
give some frost by night. Not particularly cold. No cold air near | :55:57. | :56:06. | |
our shores at the moment. Expect further spells of wind and rain. | :56:07. | :56:14. | |
Hopefully nothing coming as extreme as we have seen over the last few | :56:15. | :56:17. | |
days. To start the rest of the week it will be blustery, not | :56:18. | :56:22. | |
exceptionally so. Colder than it has been, some rain at times, no sign of | :56:23. | :56:26. | |
the wind coming in from the north and east for a sustained period to | :56:27. | :56:29. | |
aid the migration. What does this weather mean for | :56:30. | :56:43. | |
wildlife? It might affect the migration because we will not be | :56:44. | :56:47. | |
expecting too many birds from Scandinavia which typically at this | :56:48. | :56:50. | |
time of the year would be flooding in. They will not fly into a strong | :56:51. | :56:55. | |
headwind. There are other species who might take advantage, pink | :56:56. | :56:59. | |
footed geese and Hooper Swans have been seen arriving today. They have | :57:00. | :57:07. | |
been coming from Greenland, via Iceland, flying into the Atlantic | :57:08. | :57:11. | |
towards the UK with some of the north-westerly winds. They will use | :57:12. | :57:17. | |
that to carry them forward. The storm might have held it up for just | :57:18. | :57:22. | |
about a day, but migration will probably be underway towards the end | :57:23. | :57:26. | |
of the week from Scandinavia, maybe next week. Remember to look out for | :57:27. | :57:34. | |
those birds. While I was out there I heard geese flying over us. They | :57:35. | :57:41. | |
were out there. That is all we have got time for. | :57:42. | :57:45. | |
What have we got coming up tomorrow? Urban foxes with a | :57:46. | :57:49. | |
difference, they are carrying radio collars and they will tell us about | :57:50. | :57:55. | |
their behaviour and ecology. I go to Brighton to find out. | :57:56. | :58:04. | |
And we look at young Manx shearwaters starting their first | :58:05. | :58:08. | |
migration. And what was that fight all about? We will find out what was | :58:09. | :58:16. | |
going on. That might be it from us but Nick Baker is in the studio, | :58:17. | :58:22. | |
give us a wave. He is not going to be on BBC Two, he will be online and | :58:23. | :58:25. | |
on the red button doing Autumnwatch Unsprung. Press the red button now. | :58:26. | :58:31. | |
They're one, do it! We will see you tomorrow. | :58:32. | :58:36. |
