Description: |
The male and female black duck are similar in appearance, but the male's bill is yellow while the females 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 under wings can be seen in contrast to the dark brown body. |
Typical Size: |
The male and female average 24 inches in length and weigh 2 3/4 pounds. They have a wingspan of 36 inches. |
Habitat: |
Black ducks utilize a variety of habitats, such as marshes, bogs, lakes, stream margins, fresh, brackish, and salt marshes, and estuaries. |
Breeding: |
The highest breeding densities are found in Maine and Nova Scotia. Female black ducks lay an average of 9 eggs. |
Diet: |
Black ducks dabble in shallow water to feed on plant material and small aquatic animals in freshwater habitats, and mollusks and crustaceans in coastal habitats. |
Migration and Wintering: |
High concentrations are found wintering between Long Island and North Carolina. When away from the coast black ducks use large river valleys like those of the Tennessee, Detroit and Upper Illinois Rivers. |
Flyway Patterns: |
Black ducks are most common in the Atlantic and Mississippi Flyways, with most distributed along the Atlantic coast from the Maritime Provinces to Florida. |
Flight Formation: |
Small flocks in "V's" or an angular line. Short rapid wing beats, reaching speeds of 70 MPH. |

Males have a low KWEK-KWEK and females have a loud QUACK. |
