6 INTRODUCTION. 



" complete " account of the birds of this part of Arizona, but rather 

 as an outline, partly filled in, of one phase of the subject, treating 

 primarily of tjie breeding species. It is based upon a trip of six 

 weeks' duration made by the writer during the summer of 1917 

 under the auspices of the California Museum of Vertebrate Zoology, 

 a trip made possible through the interest of Mr. E. O. McCormick, 

 of San Francisco. The itinerary was as follows : Phoenix, May 29 ; 

 Tempe, May 29 to June 5; Roosevelt, June 5 to 11, July 2 to 5; 

 Sierra Ancha, June 11 to July 2; Globe, July 5 to 7. 



About Tempe trips were made over the Papago Saguaro Monu- 

 ment, in the willow bottoms of the Salt River for several miles east 

 of the town, and through a portion of the farming section for some 

 4 or 5 miles south of town. At Roosevelt, with headquarters at 

 " The Lodge," excursions were made on foot as far as the cliff dwell- 

 ings of the Tonto National Monument, some 5 miles from the hotel 

 on the Salt River branch of the lake, and for several miles up the 

 Tonto Creek arm. Trips by motor boat were also taken, on one % of 

 which a visit was made to a breeding colony of water birds near the 

 mouth of Tonto Creek. In the Sierra Ancha I stayed at the ranch 

 of Mr. John C. Carr. This lies some 20 miles from the ferry at 

 the south end of the lake, is on the main road through the moun- 

 tains, and about 3 miles north of the divide, at an altitude of 5,410 

 feet. From this point I was able to make trips as far as the summit 

 of Aztec Peak (7,500 feet) and to the heads oi certain of the canyons 

 on the northeast slope. The birds recorded from Globe were ob- 

 served on several trips, some on foot and some by rig, along roads 

 within a radius of 4 or 5 miles from the town. 



As observations were made during the nesting season, the birds 

 seen were, with few exceptions, those that breed in the places where 

 they were found. One hundred and ten species of birds were noted, 

 nearly a third of the total number (375) known to inhabit Arizona. 

 This is probably a fairly complete list of the summer birds of this 

 section, though there are a few species (the elf owl and ferruginous 

 pigmy owl, for example) that certainly do occur here, but that were 

 not encountered by the writer. Two species were added to the list of 

 birds of Arizona as a result of the trip. One is the indigo bunting 

 (Passerina cyanea) , of which an adult male was secured June 30 at 

 Carr's Ranch, in the Sierra Ancha. The second species is the 

 Bendire crossbill (Loxia curvirostra bendirei), of which two females 

 were taken June 16, also at Carr's Ranch. While the list of species 

 here given is believed to be fairly complete as regards summer birds, 

 there are, of course, many additional species to be looked for during 

 the periods of migration in spring and fall. There is a still different 

 aggregation composed of winter visitants.
