About Mottled Duck
This is a southern look alike of the American Black Duck; the male and female are similar in appearance. The Mottled Ducks retain their pair bond for most of the year, so they are most often seen together as a pair and they do not gather together in a large flock as most other ducks do.
They are similar to a Mallard, but are smaller with shorter wings. Their overall cover is between a female Mallard and American Black Duck, leaning more towards the Black Duck.
The male has a dark brown body with golden brown V-shaped marks on the interior flank feathers. It has a buffy brown face with an unmarked throat, and a slightly darker crown and eye line and it has a yellow bill. The female is slightly paler than the male with a dull orange or olive-yellow bill with black marking on the culmen.
The call of the females is a loud quack like a Mallard but a little softer and not as harsh. The males infrequently give a short soft quake like that of a Mallard.
This duck stays close to the Gulf Coast and is fairly common there, however, you will not find it in large flocks.
It is fairly stable in its population, but when there is a drought it will decline and than rise again in the wet years.
