Unsurprisingly it has been fairly quiet on the migration front this week and, with the exception of a reasonable showing of Pomarine Skuas moving through, there has been nothing much to report. However, as we are now into the winter period any serious drop in the temperature on the continent could result in a series of cold weather movements.
We could see a further arrival of Rough-legged Buzzards and Short-eared Owls and, who knows, maybe a Snowy Owl or two.
The BirdTrack reporting rate shows what an exceptional year it already is for Rough-legged Buzzard. If it is cold enough, and waterbodies in Eastern Europe freeze over, we ought to see wildfowl on the move, Tufted Duck, Pochard and Goldeneye numbers could swell, and we might even see a good showing of Smew. Bewick’s Swans have been thin on the ground the last few winters but this could change with freezing conditions on the continent.

In these conditions Woodcock and Snipe can also be forced across the North Sea. In some years more than a million Snipe make their way here. For more on this read the Demog Blog.
A small number of Waxwings were found in the north and east during the week and a small number of Little Auks were on the move, hinting at what might be if we do get a sudden cold snap further north.

The forecast for at least the next few days is for it to remain mild, with a largely easterly airflow, which is good news for the handful of Swallows, Wheatears and warblers that are still in the country, we should also see further arrivals of Starlings and winter thrushes (Redwings, Fieldfares and Blackbirds) on the east coast. There is a hint of things cooling down for the latter part of the week, and if we do get any ground frosts we might see Lapwings and Golden Plovers on the move.
I received an email this morning from a friend who is working on a survey vessel 100 miles out in the North Sea, showing just how difficult the North Sea crossing can be even for the toughest of birds.
Hi Paul - a couple of hours ago 3 Bean Geese flew past my ship - we are more or less stationary- just riding out a nasty easterly F8/F9 gale. I lost the birds from view but 20 minutes later after battling the 33 knot easterly they returned. After circling the ship 3 times they managed a very rough and dangerous landing on the deck- after clattering and skidding into some stowed kit they shook themselves off, inspected their feet, did a brief preen then started roosting! I'm amazed they managed such a difficult landing in such a small deck space in 6-8 metre seas as well as the gale force winds!

I have some concerns about takeoff with lots of obstacles in the way but hopefully the weather will settle down tomorrow- I imagine they will stay put overnight as no one is allowed on deck on these seas.
These geese were extremely lucky and fingers crossed, they make it off the deck and on their way as soon as conditions improve - there must be lots of birds that get caught out over the sea that are far less lucky. Check out Pelagic Birder's blog for more.
