Mearns, Arizona Mountain Birds. L July 



the White Mountains and the higher spurs of the Mogollon range. Like 

 many other mountain species it ranges down hill with its young after 

 the breeding season. On Oak Creek, in the cypress belt below the 

 pines, it appears in families during the first half of August. 



Contopus pertinax. Coues's Flycatcher. — This bird was seen feed- 

 ing its young on Baker's Butte, one of the higher spurs of the northern 

 part of the Mogollon range, during the months of July and August. Its 

 habits resemble those of the smaller species of this genus, rather than of 

 the Olive-sided Flycatcher. 



Contopus richardsonii. Western Wood Pewee. — Breeds commonly 

 throughout these mountains. 



Empidonax difncilis. Western Flycatcher. — Breeds commonly in 

 the upper pines and through the spruce forest, almost reaching the 

 timber line on San Francisco Mountain. It has a song and a very sweel 

 call, besides a sharp chirp uttered when angry or frightened. 



Empidonax pusillus. Little Flycatcher. — This interesting bird, so 

 abundant in the Cottonwood and willow thickets along the lower streams 

 of Arizona, was also occasionally seen, during the summer months, in 

 the dwarf willows (Saiix rostraia) that border the tiny streams and 

 swampy hollows sometimes met with in traversing these mountains. It 

 was noted at the altitude of 9000 feet at the foot of the San Francisco peaks. 



Otocoris alpestris adusta. Scorched Horned Lark. — The Horned 

 Larks which were found breeding in the park-like openings in these 

 mountain forests up to an altitude of 10,000 feet, have recently been re- 

 ferred to this race by Mr. Jonathan Dwight, Jr., in his monograph of this 

 species, published in 'The Auk' for April, 1S90. The form breeding in 

 the neighboring valleys and low desert regions is also adusta, but not 

 typical, tending considerably toward the more northern race arenicola; 

 there would have been good grounds for the presumption that the bird 

 breeding in these high mountain districts would prove to be typical 

 arenicola; but such is not the fact. 



Cyanocitta stelleri macrolopha. Long-crested Jay. — Resident to the 

 altitude of 10,000 feet, ascending still further. On the San Franciscos, I 

 found its nest with fresh eggs at the upper limit of the pines in the second 

 week of June, 1SS7, while the nests found in the lower Mogollons during 

 the last third of May of the same year all contained young. 



Perisoreus canadensis capitalis. Rocky Mountain Jay. — A quite 

 common resident in the White Mountains of eastern Arizona; not seen 

 in the northern Mogollons or the San Franciscos. 



Corvus corax sinuatus. American Raven. — Most of the Ravens of 

 Arizona are the White-necked species, but the northern Raven is com- 

 mon in the mountain districts, nesting as low as 3000 feet, usually, if 

 not invariably, upon ledges of cliffs. 



Corvus americanus. American Crow. — Breeds commonly in the 

 pines and spruces throughout this area. It ascends to the timber line, 

 breeding in the higher firs as well as in the pines. 



Picicorvus columbianus. Clarke's Nutcracker. — Breeds abundant-
