Brewster on a Collection of Arizona Birds. 
[January 
148. Zenaidura carolinensis (Linn.) Bp. Carolina 
Dove. — An abundant species throughout most of the regions 
traversed. 
149. Melopelia leucoptera (Linn.) Bp. White-winged 
Dove. — This Dove was not uncommon about Tucson, where 
specimens were taken at intervals between April 26 and May 23. 
They frequented the mesquite tracts and fed largely on mesquite 
; ‘beans.” Their notes were similar to those of the Turtle Dove, 
but hoarser, and uttered with more apparent effort. They were 
usually rather shy. 
On the journey to California they were occasionally seen in 
dreary deserts where few other birds seemed able to support life. 
At Yuma they were actually common, but none were found to 
the westward of this point. A nest obtained July 8, on the Gila 
River, was placed in a mesquite on the side of a sand-hill. It 
contained two eggs, slightly incubated, which measure respec- 
tively i.3oX«9i and i.2oX*92. Arizona skins are identical with 
Texas ones. 
“ Iris dark orange; bill black; legs dull red; bare orbital space blue.” 
150. Chanicepelia passerina (Linn.) Swains. Ground 
Dove. — Rather common about Tucson, where a number of 
specimens were obtained. 
The Arizona males in my series are much lighter colored than those 
from Florida, and their bills, instead of being yellow or dull orange, as in 
eastern birds, are pure Indian red, with the usual dusky tip. These dif- 
ferences appear to be constant, but my material is not sufficiently exten- 
sive to enable me to judge of their bearing or importance.* In some 
generalizations, based upon the examination of fifty-six examples in the 
Smithsonian Museum, Mr. Ridgway says : f “As a rule, Florida and 
West India skins are most deeply colored,” but he does not mention any 
variations in the color of the bill, which is simply described as “yellow.” 
“Iris pink (No. 300) ; pinkish-brown (No. 301) ; bill red. tipped with 
blackish ; feet and legs pale flesh-color.” 
151. Lophortyx gambeii Nutt. Gambel’s Quail. — Spec- 
imens were obtained near Tucson, and others noted at and 
beyond Walters, a station in the Colorado Desert. The first || 
Lophortyx calif ornicus were met with in the San Gorgonio Pass, 
a day’s drive to the westward of where the last Gambel’s Par- 
tridges were seen. 
* Prof. Baird has described a var. pallescens from Cape St. Lucas, to which these 
specimens are possibly referable. See Proc. Acad. Nat. Scien. Philad., 1859.
