Description of some Nests and Eggs of Arizona Birds. 

 By T. M. Brewer, M.D. 



During my brief visit to St. Louis a few weeks since, I had an 

 opportunity to make the acquaintance of Capt. Charles Bendire, and 

 to examine his very interesting collections in Oology, made in South- 

 ern Arizona in the spring and summer of 1871. Capt. Bendire 

 devoted himself to the study of the breeding habits of the birds of 

 that region with a rare zeal and industry, and has been rewarded in 

 the discovery of an unusually large number of nests and eggs before 

 wholly unknown. Some of these I propose to briefly describe. 



Buteo montanus. Western Ked-tailed Hawk. 



This hawk was abundant in Arizona. It was found breeding as 

 early as the 6th of April. A nest was built in a large cotton-wood 

 tree, and was placed close to the trunk. It was composed of sticks 

 mingled with strips of the bark of the cotton-wood tree. The eggs, 

 two in number, in shape are of a rounded oval, a little more obtuse at 

 one end than at the other, and measure 2.39 inches in length by 1.85 

 inches in breadth. The ground color is a chalky white, marked with 

 a few scattered, irregularly shaped plashes of a light reddish-brown, 

 intermingled with a few tinged with a purplish shade. These 

 blotches are larger and more numerous at the obtuse end. All the 

 eggs in the collection of Capt. Bendire closely corresponded with the 

 one I have described, and none of them are like any egg of the Buteo
