Abstract
If breeding failure occurs and there is variation in the time of egg-laying by individual females, then even accurate counts of occupied nests during the peak of the breeding season will underestimate the total population of breeding pairs. It is shown that breeding failure, the spread of egg-laying and the frequency of counting interact in their effects on estimates of breeding bird populations based on nest counts.This publication has 1 reference indexed in Scilit:
