摘要

A new subspecies of Common Chaffinch Fringilla coelebs in North Africa is described. It is restricted to northern Cyrenaica in north-east Libya. Differences from the other North African subspecies, F. c. africana and F. c. spodiogenys, are discussed,the main ones being that males invariably possess a prominent white patch on the central nape, a hint of a white post-ocular supercilium, a more yellowish tinge both above and below, stronger yellow fringes to the tertials and wing-coverts, and a less clean blue-grey head. Reasons for not recognising the subspecies F. c. koenigi are reconfirmed. There is some variation in size and in saturation of male plumage within the range of africana, making separation of koenigi untenable.
