The Helm Guide to Bird Identification covers tough species identification issues by looking at tricky pairs or groups of birds, and comparing and contrasting their respective features. This book is designed as a companion to regular field guides, providing much additional information. As well as detailed texts, the guide includes a large number of drawings that, for each species, show variation in plumage and changes in appearances as birds age.
