Eurasian wigeon Anas penelope


Description

Be sure to look for this bird when observing a flock of its counterpart, the American Wigeon, as they often mingle. Like its counterpart, this wigeon has unusual feeding habits; it will graze on land like a goose or steal food from a diving duck as it returns to the surface. It feeds on a variety of grasses and algae.



Appearance

General: 18-20 inches in length.

Male: Rusty-brown head and green speculum. Buff crown. Gray body. Rusty-buff or pinkish-buff breast. White patch at rear of flanks. Black undertail coverts. Pale blue bill with black tip. Large white shoulder patch.

Female: Mottled gray-brown or rusty-brown body. Paler head and neck. Dusky eye patch and green speculum. Pale blue bill with black tip. Large white shoulder patch.

Juvenile: Similar to adult female.



Habitat

Marshes, ponds, lakes, and tidal flats (during non-breeding).



Nesting

7-8 cream-white eggs. They have a 24 day incubation period. Fledging occurs 40-45 days after hatching. The nest is made from grass and lined with down. It is built on the ground and usually hidden in vegetation some distance from the water.
