DOBSERV - A Double-observer Approach for Estimating Detection Probability and Abundance from Avian Point Counts
Entry ID: USGS_DOBSERV
Summary
Abstract:
Although point counts are frequently used in ornithological studies, basic assumptions about consistency in detection probabilities often remain untested. We apply a double-observer approach developed to estimate detection probabilities for aerial surveys (Cook and Jacobson 1979) to avian point counts. At each point count, one observer is designated "primary", and indicates to the other ...
