100 EXPLORATIONS AND SURVEYS WEST OF JOOTH MERIDIAN. 



SITTID^E (the Nuthatches). 



16. Sitta, carolinensis Gm., var. acitleata, Cass. Slender-billed Nut- 

 hatch. 



Common in the pineries. 



17. Sitta pusilla Lath., var. pyymcea, Vig. Pigmy Nuthatch. 

 Abundant. In summer exclusively pinicoline, but iu the fall it is 



often seen in the groves of evergreen oaks. Gregarious, or nearly so, at 

 all seasons. In the fall it gathers together in flocks of fifty or more, 

 and, in company with the warblers and titmice, may be seen constantly 

 on the move in search for food, when its loud iveet-weet is continually 

 emitted as it moves along the branches or takes flight. 



CERTHIID^E (the Creepers). 



18. Certhia familiar is L., var. americana, Bon. Brown Creeper. 



Perhaps not uncommon. I saw but few, and only among the pines of 

 the mountains. 



TROGLODYTID^E (the Wrens). 



19. Campylorliynclms brunneicapillus (Lafr.) Cactus- Wren. 



The region along the Gila Elver, in Arizona, seems eminently adapted 

 to the habits of this bird, as the various species of cacti, the thickets of 

 which it specially frequents, are nowhere more numerously represented 

 than here. While along the river, the middle of September, though I 

 searched carefully, I saw but a single individual. Its actions suggested 

 those of the Winter- Wren. It had taken refuge in a dense thicket, from 

 which its harsh, scolding notes could be heard as it passed from one 

 part to another, keeping itself carefully hidden from view. Its curi- 

 osity finally inducing it to venture to the top to watch me, I secured it. 



20. Salpinctes obsoletus (Say). Eock-Wren. 



This is an abundant species throughout Eastern Arizona, everywhere 

 frequenting the masses of broken rocks, and showing an especial pro-
