Detectability of breeding birds

Speaker: Ali Johnston (University of Cambridge)

Abstract

The aim of this work is to estimate what proportion of birds breed at various ages. Existing methods such as Pradel cannot be used, as various assumptions are violated. Therefore, I’m trying to estimate the number of pairs which nest in a given breeding season, but are not detected, using closed population mark-recapture methods within the breeding season. I will compare the initial results, and hopefully spark discussion on other possible approaches to this problem.
