1914 BIRDS OF ARIZONA 43 



181. Empidonax wrighti Baird. 



Wr 1 ( ; 1 it Flycatc h er. 



Synonym — Empidonax obscanis, part. 



Status — A fairly common migrant, at least in eastern Arizona. I know of 

 no authentic instance of the breeding of this species in the state. 



[82. Empidonax griseus Brewster. 



Gray Flycatcher. 



Synonyms — Empidonax obscurus, part ; Empidonax wrightii, part. 



Status — This species and the last (E. wrightii) have been so hopelessly con- 

 fused in years past that it is impossible to allocate the various citations with ac- 

 curacy, but it is certain that E. griseus has been many times mentioned under the 

 name of the allied species. Both are migrants in Arizona, and both probably oc- 

 cur (E. griseus certainly) across the breadth of the state. Of neither form, how- 

 ever, is there any undoubted breeding record for Arizona. E. griseus is prob- 

 ably to be found in winter in the wanner parts of southern Arizona, and along 

 the lower Colorado River. 



183. Empidonax fulvifrons pygmaeus Coues. 



Buff-breasted Flycatcher. 



Synonyms — Empidonax pygmaeus; Mitrephorus pallescens ; Mitrcphorus 

 fulvifrons var. pallescens. 



Status — A summer visitant, nowhere very common, but found in several of 

 the mountain ranges of southeastern Arizona. It breeds mostly at the lower edge 

 of the Transition zone, but is very locally distributed — thus it may be fairly com- 

 mon in one canon, and almost unknown in an adjoining one. Has heen 

 found breeding in the Chiricahua, Huachuca, and Santa Rita mountains, and mi- 

 grating birds have been taken at Forts Apache and Bowie. The subspecies was 

 described from a specimen secured by Coues at Fort Whipple, which would seem 

 to be its extreme northern limit. It has so far not been found in the Mogollon 

 Mountains, which lie south of that point, but the fact of its breeding at Inscription 

 Rock, New Mexico — close to the Arizona boundary (Henshaw, 1874, p. 128), 

 points to the probability of its doing so in the Mogollons. 



184. Pyocephalus rubinus mexicanus Sclater. 



Yermiliox Flycatcher. 



Synonyms — Pyroccplialns rubineus; Pyrocephalus mexicanus. 



Status — An abundant resident along the wooded streams of southern and 

 western Arizona, locally migratory, but occurring in the warmer parts of the re- 

 gion throughout the year. In a general way it may be said to be restricted to the 

 Lower Sonoran zone in the valleys of the Colorado and Gila rivers, and their 

 tributaries. In central Arizona it extends north to Fort Verde (Coale. 1894, p. 

 218) ; casually to Fort Whipple (Coues, 1865, pp. 163. 538, 1 specimen) ; along the 

 Colorado River, to the Big Sandy. Bill Williams River, and Ehrenberg (Stephens. 

 1903, p. 102), casually to Fort Mohave (Cooper, T870, p. 333; one seen May 24). 

 In eastern Arizona does not range north of the Salt River.
