Training guide for bird identification in Pacific Northwest Douglas-fir forests.

Abstract

Bird calls and songs vary regionally, and some birds emit a variety of sounds. Existing guides are inadequate for training observers to do detailed surveys of bird communities, because more than 90 percent of birds detected are identified by the sounds they emit. This guide summarizes existing guides and adds the observations of the compilers and other technicians who participated in extensive surveys. Four-letter codes for species names, taken from the American Ornithologists' Union, are included. A checklist by region (southern Washington, Oregon Cascade Range, Oregon Coast Ranges, and northwestern California) of birds found in Douglas-fir (Pseudotsuga menziesii(Mirb.) Franco) forests west of the crest of the Cascade Range completes the guide.
