This book deals with all passerines regularly occuring in Europe and some which are only rare vagrants. It is meant to serve as a handy reference book and reminder primarily to the ringer of fledged birds, but should also be of some help when studying skins in museums. Even keen and amibitous bird-watchers in the field should benefit. It presents wing-formulae, measurements, plumage details and other information that will help identify sexes and ages, but also species and some characteristic subspecies.
