BIRDS OF PAPAGO INDIAN RESERVATION, ARIZONA 
49 
while we took the eggs, and both gave continual utterance to a loud, sharp, chip. 
Guiraca c. lazula. Western Blue Grosbeak. Fairly common about the culti- 
vated fields and pastures of the Indians. One or two broods of young were seen 
flying about. 
Piranga r. cooperi. Cooper Tanager. Fairly common, and breeding every- 
where in the mesquite forest, but very shy and hard to approach. 
Progne s. hesperia. Western Martin. While working in the giant cactus on 
the hill before described, a number of purple martins were observed flying about, 
and many of them were seen entering holes near the tops of the tallest plants. 
Several of the birds were shot, but they had evidently not yet begun to lay, though 
from their actions I think there is no doubt that they intended to occupy the holes 
in the cactus later on. Though most of the species found breeding at this spot 
were near the base of the hill, the martins stayed near the summit for the most 
part, and the holes they were seen flying in and out of were near the tops of the 
tallest of the cactuses. 
A little later we saw the birds as far up the Santa Cruz River as we went, 
about forty miles, while on our return from the Santa Rita Mountains at the end of 
June, they could still be seen flying about the summit of this little hill. 
Riparia riparia. Bank Swallow. One or two seen along the banks of the 
Santa Cruz River. They probably bred there though no nests were found. 
Phainopepla nitens. Phainopepla. Very common, and breeding every where 
in the mesquites. 
Lanius 1. excubitorides. Wliite-rumped Shrike. A few seen on the open 
mesa. Not very common. 
Vireo pusillus. Least Yireo. Found breeding in abundance all through the 
mesquites, just as in the willow bottoms in California. 
Helminthophila luciae. Lucy Warbler. Exceedingly common, and breeding 
everywhere in the mesquites. Nests were found in old woodpecker holes, in 
natural crevices and behind loose bark, even in old verdin’s nests, in fact in almost 
any place that would support the structure. As a rule they were built rather low 
down, from three to fifteen feet above the ground. Several broods are probably 
raised, as unfinished nests and incomplete sets were found at the same time that 
broods of young as large as the adults were seen flying about. 
Dendroica ae. sonorana. Sonora Yellow Warbler. A few were seen in the 
cottonwood trees near the Indian agent's house. Just a single bird was seen in 
the mesquites, and I doubt very much if any breed there. 
Icteria v. longicauda. Long-tailed Chat. Very common. The varied notes 
of this bird could be heard on all sides from morning till night. Among his other 
vocal accomplishments the chat seems to be a pretty good mimic at times. I went 
in pursuit of one near camp several times under the impression that it was an 
olive-sided flycatcher, wondering what that bird could be doing here at this time 
of the year. I could hardly believe it was a chat, even when I saw the bird, 
so good was the imitation. 
Mimus p. leucopterus. Western Mockingbird. Quite common in the mesquites. 
Toxostoma c. palmeri. Palmer Thrasher. Seen occasionally in the mes- 
quites, but much more abundantout on the mesa, where it breeds in large numbers. 
Toxostoma bendirei. Bendire Thrasher. Quite common on the mesa. I do 
not recall seeing any in the mesquite forest. 
Toxostoma crissale. Crissal Thrasher. Breeds in the mesquites but not in 
any numbers. They were shy and retiring in their habits, and though fre- 
quently heard singing, when approached they became silent, slipping away into
