May, 19o 5 [ BIRDS OF THE SANTA RITA MOUNTAINS, ARIZONA 8x 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. Helminth0pila lucia?. 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. Dendr0ica nigrescens. Black-throated Gray Warbler. Quite common every- where in the oak brush. Set0phaga picta. Painted Redstart. It was in the same canyo.n, 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. leuc0pterus. Western Mockingbird. Quite common in the lower parts of the mountains. T0x0st0ma c. paltoefl. Palmer Thrasher. Very abundant out on the mesa, and frequently seen in the lower canyons. T0x0st0ma bendirei. Bendire Thrasher. Common in the me, sa just below the mountains, but not seen in any of the canyons. Hele0dytes b. c0uesi.. 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 0bs01etus. Rocl? Wren. Fairly common along the rock-strewn foothills. Catherpes m. c0nspersus. Canyon Wren. Quite abundant. Many full grown juveniles were seen, usually two or three together. Thry0manes b. bairdi. Baird Wren. Seen along the canyons, but not in any numbers. Tr0g10dytes 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. nels0ni. Rocky Mountain Nuthatch. A few pairs were seen in the higher parts of the mountains, but they were not at all abundant. Parus w011weberi. Bridled Tit. Very abundant in the oak regions, where troops of young accompanied by the parents, were met with continually. Psaltriparusplumbeus. 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?, which I believe to be the juvenile, not of P. 110ydi as has been lately claimed, but ofplumbeus. 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 plumbeus. 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 plumbeus is abundant in both ranges. Auriparus fiaviceps. Verdin. Very common in the foothill regions, and over the mesa below. P01i0ptila plumbea. Plumbeous Gnatcatcher. Not common. Seen occasion- ally just below the mountains, but not ascending into the canyons at all.
