Population Parameters and
Philopatry of Breeding Female Wood Ducks
R. Hepp, Richard T. Hepp, and Robert A. Kennamer
Capture-recapture methods were used to estimate
population size, survival rate, and recruitment to a breeding population of
female wood ducks (Aix sponsa) in 1979-86.
A total of 181 females was captured in nest boxes and banded during the
8-year period. Population size
averaged 44 individuals. Mean annual survival rate was 0.55, and annual recruitment
averaged 22 females. Data were used
to illustrate the philopatric behavior of female wood ducks during the breeding
