147. Marila vallisneria. 21 in.

Differs from the Redhead in the shape of its black bill, its blackish forehead, very light back and red eyes. The female has the back grayish-brown, finely barred with black. Like the last species, Canvas-backs are excellent swimmers and divers, and can secure their food from a considerable depth. In winter they are found in great abundance on the Atlantic coast from Maryland southward, and are one of the most persistently hunted birds, for their flesh is much esteemed, and they have a high market value. They are seen in large flocks, and are difficult to approach, but are said to decoy as easily as any other.

Notes. - Harsh croaks, little different from those of the Redhead.

Nest. - On the ground in marshes or sloughs, the hollow being lined with grasses and feathers from the breast of the female; 6 to 10 eggs (2.40 x1.70).

Range. - Breeds in the interior from Minnesota and Dakota northward; winters from Maryland and British Columbia southward. Rare in New England.
