The Grey Buzzard-Hawk of Central America is easily distinguished from its southern 
relative, A. mitida, by its more uniformly grey coloration, and by the absence of the 
light bars which are visible in the last-named species. 
As will be seen by the list of localities given above, A. plagiata is very generally 
distributed throughout the countries of Central America as far south as Costa Rica. 
In Mexico Sumichrast. says that it is one of the most abundant of the Birds of Prey 
in the south, east, and west of the country!*. Herrera”? speaks of it as being very 
plentiful in the more southern parts of the Valley of Mexico, especially in summer 
and autumn. 
In Guatemala it is abundant in the low country bordering both coasts, occurring 
more sparingly inland. 
Robert Owen found it breeding at San Gerénimo. He states *4 that the nest is usually 
placed in high trees which are scattered over the plain, not unfrequently within a few 
yards of the Indian ranchos. Two pure white eggs are the usual complement; the 
inner coating of the shell is sea-green, a character which suggests the relationship of 
Asturina with Astur. 
A. plagiata has been known to nest in the province of Tamaulipas, but it doubtless 
breeds throughout the greater part of Mexico; in Costa Rica it is apparently rare, and 
may be only a winter migrant’®. In the south of Arizona and New Mexico it is a 
summer Visitor, arriving early in March or April, Bendire thinks that it may perhaps 
nest along the Lower Rio Grande Valley in Texas as well. In Arizona the nest is
