This Hawk has a very limited range within the United States, and Mr. Audubon, who was the first to meet with it there, obtained only a single specimen from Louisiana. Supposing it to be an undescribed species, he named it in honor of his friend, Mr. Edward Harris. [Illustration: _Parabuteo harrisi._] This species is occasionally found in the lower portions of the States of Mississippi and Louisiana, but becomes much more abundant in the southwestern sections of the latter State, and in Texas is common, especially about the mouth of the Rio Grande. In one variety or the other it is frequently met with throughout Mexico, and Central America, and is also said to be an occasional visitant of Cuba and Jamaica. Mr. Dresser found this Hawk common throughout Texas to the Colorado River, beyond which he noticed but few. It was the only Hawk he noticed at Matamoras in the summer. He describes it as a heavy, sluggish bird, seldom seen on the wing, and subsisting, so far as he could see, entirely on carrion. All along the road from Brownsville to San Antonio, he noticed it either perched on some tree by the roadside, or busy, in company with Vultures and Caracaras, regaling on some offensive carrion. He found it breeding in the neighborhood of San Antonio, Medina, and Altascosa Rivers, having eggs in the month of May. A nest found on the 4th of May, near the Medina River, was built of sticks, very slightly lined, and was placed in a low hackberry-tree. The eggs were four in number, and described as white, with a faint bluish tinge, very sparingly spotted and blotched with red.
