183. Buteo platypterus. Broad-winged Hawk. 



Winter resident from the northern border south to the Rio Grande. 



184. Urubitinga anthracina. Mexican Black Hawk. 



Occasional along the Valley of the Lower Rio Grande. 



185. Archibuteo ferrugineus. Ferruginous Rough-leg. 



Western half of the State, east to Bexar and Comal counties, etc. 

 Breeds abundantly in the Panhandle (Potter and Armstrong counties). 



186. Aquila chrysaetos. Golden Eagle. 



Western half of the State, resident in the mountains of the trans- 

 Pecos region and in the canyons of the Panhandle. Straggles east to 

 Waco, Refugio, etc. Hancock's Corpus Christi record is based on the 

 Bald Eagle which breeds commonly in that section. 



187. Thrasaetos harpyia. Harpy Eagle. 



Delta of the Rio Grande, one specimen, only record from North Amer- 

 ica (Oswald, Am. Nat., 1875, p. 151.) 



188. Haliaeetus leucocephalus. Bald Eagle. 



Southern and Eastern Texas, resident, locally distributed. Breeds in 

 Neuces, San Patricio, Bee, Refugio, Goliad, and other counties in the 

 southeastern section, this region seeming to be the center of their dis- 

 tribution in Texas. Recorded as common resident in Western Texas 

 by Lloyd, although the present writer has never observed it in that 

 section. 



189. Falco mexicanus. Prairie Falcon. 



Western Texas, resident along the edge of the plains in the Panhandle, 

 on the southern plains and in the trans-Pecos region. I am a little 

 doubtful of Nehrling's Houston breeding record. 



190. Falco peregrinus anatum. Duck Hawk. 



Winter visitor, not common. May possibly be resident west of the 

 edge of the plains. 



191. Falco coliunbarius. Pigeon Hawk. 



Winter resident, not common.

Rare winter resident. Recorded from Refugio county by Carroll.

Lower Rio Grande Valley (Cameron and Hidalgo counties) westward 

 to El Paso. In the west, breeds north on the plains as far as Midland 

 and Ector counties. Summer resident.
