|Eurasian Nuthatch, Sitta europaea caesia|
After Blue Tits and Great Tits, one of the British Birds most likely to be seen at a feeder in a garden, especially near woodland, is the Eurasian Nuthatch Sitta europaea. This species is currently doing well in the British Isles, and is currently spreading northward in Scotland, although it is currently absent from Ireland. There are at least 20 subspecies, with a range from western Europe across to China and South Korea, and southwards into the Caucasus. The form in the UK is caesia, which is also found in much of western Europe, and is typical of a group of subspecies with buff underparts and a white throat. Further east from Scandinavia across Siberia the europaea group has white underparts, and finally in China the sinensis forms have the throat and underparts pale buff.
