ish at base both above and below; cere, legs, and feet, jellow; 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. Ridgvyay in " History of North 

 American Birds" (Vol. Ill, p. 273).

146. Asturina nitida plagata {Licht.) Ridgxv. Mex- 

 ican Goshawk. — ''A common species in some of the mesquite 

 groves about Tucson. Flight Falcon-like and very swift. The 

 cry is a loud '■cr^tr' 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, 

 vs^as 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 

 3.04X1-65. 



Among the adults collected by Mr. Stephens I find little variation in 

 either color or markings, and the sexes diifer 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.

147. Cathartes aura {Linn.) lUig. Turkey Buzzard. 

 — Incidentally mentioned in the notes as being common near 

 Tucson. A large Vulture seen at Cave Creek, March 7, was 

 thought by Mr. Stephens to be Pseudogryphus californianns.
