The influence of environment, sex, age and paired status on behavior of common goldeneyes was also investigated. I used censuses to determine distributions, focal- animal sampling to quantify behavior,and habitat and weather characteristics to describe environmental conditions. Differences in distribution between male and female and between paired and unpaired common goldeneyes (Bucephala clangula)wintering in Maine were related to specific habitat and climatic variables. Wind speed, wind direction, time-of-day, tide stage, date,and site explained differences in distribution between males and females in early winter. In late winter, sex-specific distribution was attributed to wind direction, type of substrate, and time-of-day. The relative importance of substrate type in explaining distribution of males and females may be related to t
