Up close it is olive-brown on the back and the head and underneath are blue-grey. It has a red bill with a yellow tip. It breeds in the UK in lowland areas, especially in central and eastern England. It is scarce in northern Scotland and the uplands of Wales and northern England. UK breeding birds are residents and seldom travel far.
