Water Birds of California (California Natural History Guides)

Fair used paperback.  Spine is faded, front cover has tear at bottom edge.  Corners of some pages are curled, several pages are water stained.  Previous owner's pencil notes on some pages.

This book is a practical, convenient guide to species recognition.  Three "picture keys" will guide the reader quickly from drawings to species descriptions.  These enable even an inexperienced observer to make positive identifications.   Introductory general chapters treat feeding, flocking, migration, nesting, habitat use, and conservation.  Other chapters cover techniques in observing and record-keeping.  Another special feature is an appendix that graphically summarizes information on actual abundance in preferred habitats and in different districts. An essential guide for serious students of California water birds.  With illustrations by Gene M. Christman.
