ish at base both above and below; cere, legs, and feet, yellow; claws 
black. The stomach contained two lizards, a few fish scales and some 
feathers. Sexual organs very minute.” This specimen is in nearly the 
same plumage as the one described by Mr. Ridgway in “ History of North 
American Birds” (Vol. Ill, p. 273).

146. Asturina nitida plagata ( Licht .) Ridgw. Mex- 
ican Goshawk. — U A common species in some of the mesquite 
groves about Tucson. Flight Falcon-like and very swift. The 
cry is a loud Rrur' repeated four or five times in succession. 
At a distance it sounds much like the scream of a Peacock.” 
The stomachs of the specimens examined contained lizards, 
small squirrels, fish scales, the wing-covers of beetles, and unrec- 
ognizable fur and bones of small rodents. A nest found May 2, 
was placed in the fork of a cottonwood about forty feet above the 
ground. It was composed outwardly of cottonwood twigs and 
was lined with leaves. The single egg which it contained is 
white with a faint bluish tinge. It is ovate in shape and measures 
2.04X1-65. 
Among the adults collected by Mr. Stephens I find little variation in 
either color or markings, and the sexes differ only in size. A male killed 
early in May represents the now well-known immature condition which 
curiously resembles that of the Broad-winged Hawk.
