360 BUTEO PENNSYLVANICUS, BEOAD-WINGED BUZZAED. 



marked with chestnut, chiefly in cross-bars alternating with whitish, but on the flanks, 

 and sometimes across the belly, these markings quite blackish. The general tone of 

 the under parts may be quite as dark as the pectoral area of the male, but it lacks 

 uniformity, and the increased depth of color of the pectoral area in this sex suffices to 

 preserve the strong contrast already mentioned. (About forty specimens examined.)

This species was not noticed by either of the Expeditions, and the 

 only Indication I have found of its presence anywhere in the Missouri 

 region is Prof. Snow's record of its occurrence in Kansas, where it is 

 said to be not common. Its longitudinal dispersion is thus quite re- 

 stricted, contrary to the rule among our birds of this family, most of 

 which range across the continent. The Broad-winged Hawk is appar- 

 ently more numerous along the Atlantic coast than elsewhere, especially 

 in New England, where all the local writers speak of it, some giving it 

 as the most abundant summer Hawk in certain localities, as about 

 TJmbagog Lakes. It is known to breed in various parts of New En- 

 gland ; further south it is chiefly observed in the fall and winter, the 

 only seasons when I saw it about Washington, D. C. I did not meet 

 with it in either of the Carolina.s, but it is given as common in Florida, 

 known to reach southward as far at least as Ecuador, as by the above 

 quotations, and to reside in Cuba. 



The nest of this species has but seldom fallen under the notice of 

 natnralists. Dr. Brewer describes the one that Audubon saw, and 

 another taken by Prof. Adams, now in the museum of Middlebury Col- 

 lege,- Vermont. Mr. Samuels states that a nest he visited the 20th of 

 May, 1864, in West Eoxbury, Massachusetts, was built in the fork of a 

 tall pine-tree, near the top, and composed of coarse sticks and twigs, 

 lined with red cedar bark, leaves, and feathers. It contained four eggs, 

 measuring from 2.00 to 2.15 long, by 1.70 to 1.72 broad ; " dirty yellowish- 

 white, covered more or less thickly in the different specimens with spots 

 and blotches of reddish-brown." Other specimens had fainter mark- 

 ings, while in others again the spots were finer and darker.
