1 8 Scott on the Birds of Arizona. [January 



to be hatched, very similar to those of M. crinitus, save that they are a 

 little larger. But one brood is reared in the Catalina region. About 

 Tucson they nest commonly in deserted Woodpecker holes in the giant 

 cactus. 



109. Myiarchus cinerascens. Ash-throated Flycatcher. — An abun- 

 dant migrant and summer resident, breeding throughout the region in 

 suitable localities. It arrives in the Catalinas about the 20th of March, 

 and on the plains somewhat earlier; a few probably spend the winter at 

 the lower altitudes in the extreme southern portion of the Territory. I have 

 no records that indicate a later stay in the Catalina or Pinal Mountains 

 than about the last of September. The nests are placed in deserted Wood- 

 pecker holes and in natural cavities in almost any kind of tree, and also 

 in the giant cactus. Two broods are reared at the lower elevations, and 

 from three to five eggs are laid. 



[A half-fledged nestling is much darker in color above, and less gray on 

 the throat and breast, than are the adults. The head in the young bird is 

 decidedly blackish brown ; the rest of the dorsal plumage dark brown. 

 The wing-coverts and inner secondaries are edged with reddish brown 

 instead of white, and the rectrices are broadly edged externally with 

 rufous, without white edging on outer pair. The dusky area is much nar- 

 rower and blacker than in adults. — J. A. A.] 



no. Myiarchus lawrencei olivaceus. Olivaceus Flycatcher. — My 

 personal experience with this species is limited to the capture and record 

 of but a single individual. It was taken in a canon in the Catalina Moun- 

 tains, at an altitude of 5000 feet, and is catalogued as "No. 66, $ , 13th 

 June, 1S84." Mr. F. Stephens found the species commonly in the Santa 

 Rita Mountains. 



in. Sayornis saya. Say's Phoebe. — Common winter resident, and 

 a regular though not very common migrant and summer resident, breed- 

 ing sparingly, in the Catalina Mountains. My earliest records of it, near 

 my residence, are about the first of March, and it remains till the approach 

 of cold weather. My latest notes of it in fall are 20th and 21st of Decem- 

 ber, 18S5, when I saw one each day; altitude, 4000 feet. It winters com- 

 monly on the San Pedro River, about twelve miles from the point 

 indicated in the Catalinas. 



112. Sayornis nigricans. Black Phcebe. — Not so common as the last. 

 A regular resident in the valleys about water courses, and a migrant and 

 summer resident in the Catalina Mountains. I first noted its arrival (al- 

 titude, 4000 feet) on March 25, 1S85, and it remains at this point till cold 

 weather comes on. A number of young birds in the collection were 

 taken in the Catalinas about the middle of July. I noted the bird on the 

 San Pedro River, January 2S-30, 1886, when only a few were seen. 



113. Contopus borealis. Olive-sided Flycatcher. — A rather com- 

 mon spring and fall migrant in the Catalina Mountains, and also noticed 

 once in early August in the Pinal Mountains. I have been unable to 

 ascertain whether it breeds in the Catalinas. In spring in the Catalinas 

 (altitude, 4500 feet), it appears for a few days late in April, and the earliest
