Water Birds of California (California Natural History Guides)

Good used paperback.  Spine is faded, front cover curls.  Corners of some pages are curled; foxing along outer edge.

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.
