Calton: Poyser, 1989. Octavo, illustrations, fine copy in dustwrapper.

This book by a trio of rare-bird specialists is a successor to two earlier works (long out of print), Scarce Migrant Birds in Britain and Ireland (Sharrock 1974) and Rare Birds in Britain and Ireland (Sharrock 1976). It unifies both of the earlier works and updates them, adding more than 80 species to the previous total.
