Small passerine waifs from North America and Canada can make their way over to the UK in very small numbers each Autumn. Weather patterns play an important role in bringing them over to Europe. This year has been good for American vagrants on this side of the Atlantic.
Swainsons’s Thrushes are Nearctic birds that breed in the Northern States of the USA and Canada and winter in the foothills of the Andes in South America.
It’s been a while since I’ve seen a Swainson’s Thrush so well as the one I saw this week on the Island of Tresco in the Scillies.
