Hooded Merganser

Hooded Mergansers were common this December in both Olympia’s Capitol Lake and in Puget Sound. This drake appeared to be interested in the two hens he swam near. At one point, when the hens were not looking, he turned for some tail feather care. Tail-cocking by males is associated with pair bond maintenance. Usually tail-cocking is done by a male swimming ahead of a female. Pair bonds are seasonal, but form in mid-winter (Dugger et al. 2009).
