(Martin's away filming in Siberia, but to keep the spirit of Unsprung going we thought we'd post this little quiz - Jeremy, Autumnwatch web producer.)

Do you recognise these birds from their colourschemes?
Update: Some of you got these straight away, so we've added a few very difficult bonus images.
