Greater Scaup, Aythya marila, Nest Site Characteristics on Grassy Island, New Brunswick
We studied Greater Scaup (Aythya marilla) nest site selection on Grassy Island, New Brunswick, during 1995 and 1996 by describing site selection in relation to habitat characteristics and association with larids using univariate comparisons. We pooled nesting data from both years and found that nest...
