Description
Black ducks are similar to mallards in size, and
resemble the female mallard in coloration, although
the black duck's plumage is darker. The male and
female black duck are similar in appearance, but the
male's bill is yellow while the female?s is a dull
green. The head is slightly lighter brown than the
dark brown body, and the speculum is iridescent
violet-blue with predominantly black margins. In
flight, the white underwings can be seen in contrast
to the dark brown body.

Breeding
American Black Ducks nest on or near the ground,
generally close to water. Dense clumps of vegetation
help to obscure shallow depressions lined with plant
material and feather down. The female incubates 9 to
10 eggs, rarely leaving the nest during the final few
days before hatching. Immediately after hatching,
chicks can swim and find food on their own.

General Comments
Black Ducks congregate in large groups in the fall
and winter, when pair bonds form. Pairs remain
together through the winter and into the breeding
season. Once the eggs are laid and the female begins
incubation, the pair dissolves. At this time the males
molt their feathers and go through a month-long period
of flightlessness while their new feathers grow in.
Once the young fledge, the females go through the same
flightless molt. By August, both sexes are able to fly
again.
