ARCHIBUTEO SANCTI JOHANNIS — BLACK HAWK. 225 



with stripes and oblong spots of brown ; the tail is numer- 

 ously barred. 



Being very abundant throughout the State, the habits of 

 this species may be studied with great ease. The young 

 can generally be found in the nest by the middle of April, 

 or even earlier. 



Specimens in the Museum of the Cleveland Academy of 

 Natural Science. 



V. Genus Archibuteo, Brehm^ Bis 1828. 



Character similar to those of the preceding genus, but 

 with the tarsi feathered to the base of the toes, but more 

 or less naked on the hind part. Toes short; claws moder- 

 ate ; wings rather long. Species of this genus are found in 

 both the eastern and western hemispheres, A. logopus being 

 considered common to both. Three species inhabit the 

 United States.

Many naturalists consider this species identical with A. 

 logojncs of Europe, while others look upon them as quite 

 distinct. Cassin says that specimens of what has been con- 

 sidered the young bird, agree in all respects with individ- 

 uals from Europe, and that it is impossible to distinguish 

 any difference. As both species — if there are two of them 

 — are indiginous to this continent, and breed in the far 

 countries of the North, coming South at the approach of 

 winter, and leave us in March or April for their breeding 

 places, it is rather difficult to decide, vmless living birds of 

 the light colored plumage are obtained and kept in confine-
