BIRD BEHAVIOR by Philip S. Callahan


Email this review


Callahan, whose specialty is insects but who demonstrated his expertise on birds in last year's Magnificent Birds of Prey, begins with reminiscences of his own early bird watching and uses his observation charts (i.e., ""frequency of occurrence of winter residents observed on weekly trips in the Flood Plain Area"") as examples throughout. The book mixes up-to-date information on anatomy, feeding, reproduction, nesting, habitat, territoriality, defense, migration and communication with procedural suggestions for serious bird watchers. The tips range from an endorsement of the Golden Press field guide (Birds of North America) to a two-page ""outline for a life history study."" The mere titles of some of the tables (for one, Wisconsin's Dr. Young's ""Spring Phenology for the Robin at Ho-Nee-Urn"") could scare off casual window observers but in reality Callahan's authoritative, uncondescending introduction will be clear to any beginner and a boon for those who like to do things systematically.
