BIRDS OF THE SANTA RITA MOUNTAINS, ARIZONA 
Vireo pusillus. Least Vireo. Not common, but a few were seen in the lower 
parts of the range, and in the bush, out on the mesa as well. 
Helminthopila luciae. Lucy Warbler. This is another species, that, breeding 
abundantly in the Santa Ritas, is seldom seen in the neighboring range, the 
Huachucas, and then only during the migrations. In the neighborhood of our 
camp, and in the ravine below, it was very common, being one of the few species 
that was really abundant. Both adults and juveniles were taken. 
Dendroica nigrescens. Black-throated Gray Warbler. Quite common every- 
where in the oak brush. 
Setophaga picta. Painted Redstart. It was in the same canyon, several 
miles above the location of our camp, that Mr. Stephens took the first known set 
of eggs of this species years ago. Some of the birds were seen at various points 
along the canyon, but they were not nearly as abundant as I had found them in 
the Huachucas shortly before. That they were breeding was evidenced by the 
number of juveniles seen. 
Mimus p. leucopterus. Western Mockingbird. Quite common in the lower 
parts of the mountains. 
Toxostoma c. palmeri. Palmer Thrasher. Very abundant out on the mesa, 
and frequently seen in the lower canyons. 
Toxostoma bendirei. Bendire Thrasher. Common in the mesa just below 
the mountains, but not seen in any of the canyons. 
Heleodytes b. couesi.. Cactus Wren. Very abundant on the mesa and along 
the foothills. Adults and juveniles were seen everywhere, but as usual, they were 
so shy and wary as to be almost unapproachable. 
Salpinctes obsoletus. Rock Wren. Fairly common along the rock-strewn 
foothills. 
Catherpes m. conspersus. Canyon Wren. Quite abundant. Many full grown 
juveniles were seen, usually two or three together. 
Thryomanes b. bairdi. Baird Wren. Seen along the canyons, but not in 
any numbers. 
Troglodytes a. aztecus. Western House Wren. Found here, as in the Hua- 
chucas, in the higher parts of the range only. Usually seen about fallen trees or 
in brush piles. 
Sitta c. nelsoni. Rocky Mountain Nuthatch. A few pairs were seen in the 
higher parts of the mountains, but they were not at all abundant. 
Parus wollweberi. Bridled Tit. Very abundant in the oak regions, where 
troops of young accompanied by the parents, were met with continually. 
Psaltriparus plumbeus. Lead-colored Bush-Tit. Quite abundant and occur- 
ring in all parts of the mountains. I took several specimens of the so-called 
P. santarit<z , which I believe to be the juvenile, not of P. lloydi as has been 
lately claimed, but of plumbeus . I took specimens with fairly well defined dusky 
lines over the auriculars, from small flocks that were evidently composed of a 
single family each, the pair of old birds and six or eight juveniles. Some of the 
young birds had, and others lacked, the lines on the sides of the head, but in every 
case the adults were pluvibeus. I have never yet met with lloydi in southern 
Arizona, and doubt if it occurs in either the Santa Rita or the Huachuca Moun- 
tains, though phoubeus is abundant in both ranges. 
Auriparus flaviceps. Verdin. Very common in the foothill regions, and over 
the mesa below. 
Polioptila plumbea. Plumbeous Gnatcatcher. Not common. Seen occasion- 
ally just below the mountains, but not ascending into the canyons at all.
