Abstract

Analyses of the capture-recapture data on 0 individual roseate terns (Sterna dougallii) trapped from 1978-1987 as breeding adults on nests on Falkner Island, Connecticut, estimate the average annual minimum adult survival rate to be 0.74-0.75. There was weak evidence of year-to-year variation in annual survival rates during the study period. The Jolly-Seber models used to estimate survival rates also generated estimates of population size and capture probabilities. To determine the relative importance of adult mortality and permanent emigration in contribuuting to the estimated annual loss of one-fourth of the breeding population will require further study of intercolony movemnet between all the major colony cities.
