HABITS. The Broad-winged Hawk appears to be distributed over eastern North America, somewhat irregularly, as far north as the British Provinces, and as far west at least as the Mississippi. It has been found in Florida by Mr. Wurdemann, where it was said to be not uncommon. It is a resident in Cuba, where it breeds; but it has not been taken in Jamaica. It has also been detected in Guatemala by Mr. Skinner. Audubon states that he never met with it in Louisiana, but Mr. Dresser found it not uncommon from the Nueces eastward. In September he noticed several near the Mission of San Patricio, and during the winter obtained several specimens near San Antonio. In May he shot a young bird on the Medina River, and early in June he found a nest containing young on the Colorado. It was on a high cottonwood-tree, and in an almost inaccessible position. [Illustration: _Buteo pennsylvanicus._] It is not mentioned by Mr. Downes as occurring in Nova Scotia, though I think it quite probable it may be found there; but it is quite common near Calais, both in Eastern Maine and in New Brunswick. Professor Verrill gives it as a common summer visitant in Oxford County, Me., near Norway, and as still more abundant near the Umbagog Lakes, and apparently the most common Hawk in that vicinity. He found its nest, June 12, containing two eggs nearly hatched. It is to be met with throughout Massachusetts, having been found breeding near Williamstown, Springfield, and also in the vicinity of Boston. Its nest was also met with in Middlebury, Vt., by the late Professor Adams. Mr. McIlwraith, of Hamilton, Canada, has noted extensive migrations of this Hawk in March of different years, as many as twenty or thirty being in view at one time, passing at a considerable height, and moving in circles towards the northwest. Others, that appeared to be stragglers from the main body, were met with in the woods. Dr. Hoy states it to be rather common near Racine, and Mr. Kumlien has obtained it in the vicinity of Lake Koskonong. From all these data it may naturally be inferred that this Hawk has a pretty general distribution from Florida to Texas, and from New Brunswick to the Mississippi Valley, probably extending northward into the Saskatchewan Valley and south-westerly to Central America. The Broad-winged Hawk was first described by Wilson, who shot a single specimen that had been feeding on a meadow-mouse. On his approach it uttered a whining whistle and flew to another tree. Another of the same species was observed, and its movements were in wide circles, with unmoving wings. Nuttall never met with it, and regarded it as very rare.
