As predicted, birds also arrived from the east. A Steppe Grey Shrike arrived in North Norfolk over the weekend, a Blyth’s Pipit was identified on the Isles of Scilly and the first 2 Radde’s Warblers of the autumn were found on Shetland, while a Little Crake graced Minsmere, Suffolk. At least four Rough-legged Buzzards were reported and the northern islands saw the largest arrival of Redwings, although we are still waiting for the main arrival of winter thrushes.
Song Thrushes, Robins, Starlings and Goldcrests have begun to move through coastal watchpoints on the Continent but the low pressure system that has been wheeling around off our west coast has largely blocked a crossing of the North Sea. However, the stormy conditions will abate over the weekend and there will be light south-westerly/westerly airflow across the North Sea, light enough to perhaps encourage a few birds to attempt a crossing.

So, we should see the first big movement of Starlings and thrushes. Bramblings should also feature in visible migration counts, and we could see the last flocks of Swallows and House Martins heading off. The latter species is of particular interest to the BTO; we have lost over half of our breeding House Martins during the last twenty-five years and whilst we know that they are faring better in Scotland and Northern Ireland than they are in England, we don’t really know why. Is it a loss of complete colonies or a general reduction in colony size and why are losses greater in certain parts of England compared to others. To help find this out we will be launching a special survey in 2015 & 2016 to gather further information. Find out more here.
