Chaffinch

Fringilla coelebs

If the Chaffinch weren't so common, the pretty male with his blue hood, pink face and head and white wing bars would be considered exotic

He has a white vent and white under- tail feathers	The lower back, usually hidden, is olive green	The wing bars are variable
The female is much plainer than the male	She has a slight pinkish tinge to her brown front	and a muted shadow of the male's pattern
A tatty one	The wing bars are variable	This one has a white eye-ring (except for the eye line)
A young male starting to colour up to breeding plumage	Possibly a young male with crest (and white eye-ring)	The white tail edge feathers show in flight
	Wing bars in flight
