SPIZAETUS.—SPIZIASTUR. 93 
by many naturalists. SS. ornatus is found in the “tierra caliente” of both coasts, 
seldom extending its range to a greater elevation than 3000 feet. 
Sumichrast !° describes the habits of this Eagle as being very like those of the Buzzards. 
He says that it never leaves the woods, awaits its prey perched, and lives principally 
upon rats and other small quadrupeds. Leyland procured only two specimens during 
his stay in Honduras; these he found in a very solitary place. The crop of one he 
examined was full, and contained small reptiles.

Of this species there is little to be recorded, although the bird is by no means rare 
in collections. Its distribution in Central America is apparently the same as that of 
S. ornatus, and, similarly, it inhabits the forest-regions, ranging to no great elevation. 
SPIZIASTUR. 
Spizastur, Lesson, Rev. Zool. 1839, p. 182; G. R. Gray, List Gen. Birds, p. 3 (1841). 
Spiziastur, Sharpe, Cat. Birds Brit. Mus. 1. p. 258 (1874). 
The single species of this genus is closely related to Spizaetus, but may be distin- 
guished by the extremely powerful claws, the hind one being especially long and 
strong. 
In size Spiziastur resembles some of the smaller Eagles of the Palearctic genus
