BALDPATE—AMERICAN WIDGEON. 137. Mareca Americana. 19 inches.
These are common and well-known birds throughout North America, where they are called by a great variety of names, most of which refer to the bald appearance of the top of the head, owing to the white feathers. They can usually be identified at a distance by the absence of any dark markings, and when in flight by the whiteness of the under parts.

GREEN-WINGED TEAL. 139. Nettion carolinense. 14 inches.
