Autumn bird migration news: Still plenty to come
Each week Paul and Nick from the BTO are updating us on all the comings and goings of autumn's bird migration. We'd love to hear what you've been seeing too, whether in your garden or out and about.

As the migration of our summer visitors comes to a close, it's easy to think that autumn migration also comes to a close. Nothing could be further from the truth. Migration watchers in early November can be rewarded with some of the most spectacular bird migrations of the year.
At this time of the year migration is very much influenced by the weather in northern and eastern Europe, with temperature all important.

A sudden freeze will see berry crops fall and waterbodies ice over, prompting cold-weather movements for thrushes (redwings, fieldfares, blackbirds, song thrushes and ring ouzel), finches (siskins, redpolls, linnets, chaffinches and bramblings), larks (skylarks and woodlarks), pigeons (woodpigeons and stock doves) and wildfowl (ducks, swans and geese).
So far this autumn with temperatures higher than normal we have seen very little of this. The daytime temperature in eastern Europe, however, is forecast to drop to near freezing this weekend, so we could see an arrival of pochard and goldeneye, along with a small arrival of Bewick's swans. [Editor's note: Slimbridge, Autumnwatch's hosts for the next four weeks, is one of the UK's best sites for Bewick's.]
Up until now there hasn't been a need for these birds to move. Check out the BirdTrack reporting rate for goldeneye.
Any cool crisp day with light winds, particularly from the east, over the next couple of weeks should prompt a big movement of woodpigeons, with flocks often tens of thousands strong heading south-west. You don't have to be on the coast to observe this migration spectacle, big flocks can be seen flying over land-locked counties too.

The first waxwings of the autumn have been seen, with a flock of 20 birds being found in Stromness, Orkney, and three seen on Lewis, Outer Hebrides. It's too early to say whether it will be a waxwing winter, but with the drop in temperature on the continent this weekend we might see a few more arrive. At this time of the year waxwings generally arrive in the north and work their way south as berries become harder to find.
Flocks of lapwings and golden plovers on the move are a sure sign that the ground is frozen on the continent, so falling temperatures there could cause an influx of these winter field inhabiting waders.
Question of the week: Is it true that some birds reduce internal organs to compensate for the extra fat they carry for migration?
This is absolutely true and is illustrated perfectly in a passage from Ian Newton's excellent book, Bird Migration. Organ reduction has been found in a number of migratory species, including pied flycatchers, willow warblers and swallows. However, extreme changes were found in bar-tailed godwits killed accidentally in Alaska as they hit a radio tower, just after take-off on a presumed trans-Pacific flight of at least 10,400km to New Zealand.
These Alaskan godwits had some of the highest fat contents recorded among birds, comprising 55 percent of total body mass. They also had relatively large breast muscles and heart (exercise organs), but very small gizzard, liver, kidney and gut (digestive organs). They had largely dispensed with parts of their metabolic machinery that were not essential during flight, presumably converting them to other tissue.
On arrival at their migratory destinations, birds rebuild their digestive organs, so that they can once again feed efficiently.

Has the reason for this event been found yet and what was it?? Does anyone else remember the news story??

First you talked over it, then you played music over it, then you go back on set and Martin emphasizes the significance of said noise of which you have just deprived us! AAAaaarrrrrrgggggghhhhhh!!!!!!
Any chance of hearing the real soundtrack without all the diversions?
Keep up all the good work.

We were on the Amsterdam to Newcastle ferry last night and saw small birds in their thousands passing the ship around 3 am last night, somewhere off East Anglia. Around 7 am off the north Yorkshire coast the starlings appeared, again in massive numbers, some of which hitched a ride for a while on the ferry, along with a solitary blackbird. Looks like they are on their way already!

An amazing spectacle.... My question is, where would they be heading? Are they arriving or leaving? I live in derbyshire and they seemed to be travelling SW.

We get alot of brids in our garden, blue tits, great tits, robins, wrens to name a few. For the past few weeks there has been a new bird, I see it mostly on the ground, under the bird table and hanging feeder. It stays quite close to the edges, near the brush and flits in and out of the bushes. It is about the size of a robin and brown all over. It does not appear to have any other colouring, no markings or anything. I am quite sure that I have never seen this bird before in our garden. I am wondering if it could be a bird that has come over from elsewhere, but I never see it in a flock, or even just in a pair. It is always on its own. I have done the RSPB bird identifier a number of times to try and identify what bird it is but am still stumped. Please help as I really want to know what it is ! When I see it next I will try and take a photo, but it flys off as soon as I go outside, I always watch it through the french doors.
Thanks for any help, again, I really love the show !! Katie xx

One year in particular I noticed that rabbits were being killed by something that would bite a chunk out of the back of their necks, no other marks being evident. Often while walking round the fields I would hear the squeal of a rabbit and go to where the sound came from to find a rabbit had just been killed, and had the bitten neck at the back. This seemed to happen at the bottom of tall hedges, and I sometimes would see a squirrel in the vicinity. I have often wondered what the culprit was, squirrel, stoat or weasel seemed likely. Could anybody clarify what was doing this?

On Tuesday of this week another beautiful day I stopped again to watch and listen as the sound was so loud and intrusive. This time there were four skylarks all together hovering/ flittering at about 30 feet they stayed and 'played' like that for about 10 minutes then all flew off in a south westerly direction. Were they a family or 'friends' meeting up to migrate together, they seemed so happy in each others company. We have the pleasure of lots of larks here but I have never seen them in a group before. I live in North Cornwall overlooking the Camel Estuary and Pentire Head,
in a wonderfully rich birding environment. Would be nice to see more Autumn or Springwatch reports from Cornwall other than Choughs and Owls.
