The Baldpate ranges over the whole of North America. In winter it is common in the Gulf states and lower part of the Mississippi Valley. Cooke says it breeds chiefly in the north, but is known to nest in Manitoba, the Dakotas, Minnesota, Nebraska, Kansas, Illinois, and Texas. Throughout the whole of British America, as far north as the Arctic ocean, it is very abundant. In October and April it visits in large numbers the rivers and marshes, as well as both sea coasts, of the northern United States, and is much sought by hunters, its flesh being of the finest quality, as when in good condition it cannot easily be distinguished from that of the Canvas-back. It is regarded by hunters as a great nuisance. It is not only so shy that it avoids the points of land, but by its whistling and confused manner of flight is said to alarm the other species. During its stay in the waters of the Chesapeake, it is the constant companion of the Canvas-backs, upon whose superiority in diving it depends in a large degree for its food, stealing from them, as they rise to the surface of the water, the tender roots of the plant of which both are so fond -- vallisneria grass, or wild celery. The Baldpate is said to visit the rice fields of the south during the winter in considerable numbers.

The favorite situation of the nest is remarkable, for while the other Ducks -- except, perhaps, the Teal, according to Mr. Kennicott -- choose the immediate vicinity of water, he found the Baldpate always breeding at a considerable distance from it. Several of the nests observed on the Yukon were fully half a mile from the nearest water. He invariably found the nest among dry leaves, upon high, dry ground, either under large trees or in thick groves of small ones -- frequently among thick spruces. The nest is small, simply a depression among the leaves, but thickly lined with down, with which after setting is begun, the eggs are covered when left by the parent. They are from eight to twelve in number, and pale buff. The food of the Baldpate consists of aquatic insects, small shells, and the seeds and roots of various plants.

The call of this bird is a plaintive whistle of two and then three notes of nearly equal duration. Col. N. S. Goss states that, as a rule, Widgeons “are not shy, and their note, a sort of whew, whew, whew, uttered while feeding and swimming, enables the hunter to locate them in the thickest growth of water plants.”
