54 PACIFIC COAST AVIFAUNA No. 10 



233. Spizella monticola ochracea Brewster. 



WESTERN TREE SPARROW. 



Synonyms Spizella canadensis; Spizella monticola. 



Status Kennerly (1859, p. 29) found this species in December on the Little 

 Colorado River, while Henshaw (18753, p. 159) reported it, on the authority of 

 Bendire, as of occasional occurrence in winter in the vicinity of Tucson. These 

 are the only records for the state. 



234. Spizella passerina arizonae Coues. 



WESTERN CHIPPING SPARROW. 



Synonyms Spizella socialis; Spizella socialis arizonae. 



Status Common summer visitant in parts of central Arizona. Found 

 breeding at Fort Whipple (Coues, i866a, p. 87), and on the Mogollon and San 

 Francisco mountains (Mearns, iScpa, p. 259). In southern Arizona it is a 

 very abundant migrant, and in the warmer valleys a winter visitant also. Ob- 

 served in some numbers along the Colorado River, from The Needles southward 

 in February, March, and April; seen at Potholes, May i. under conditions pos- 

 sibly indicative of breeding (Mus. Vert. Zool.). Two specimens taken by Cooper 

 at Fort Mohave, December 24, 1860 (in Mus. Vert. Zool.). 



235. Spizella pallida (Swainson). 



CLAY-COLORED SPARROW. 



Synonym Spizella pnsio. 



Status Henshaw (187513, p. 278) secured specimens at Camp Crittenden 

 in September; and Scott (1887. p. 200) met with the species at Mineral Creek in 

 March, October, and November. These seem to be the only Arizona records. 

 It is highly probable that Cooper's ( 1861, p. 122) reference to Spizella pallida as 

 common in April in the vicinity of Fort Mohave. really pertains to S. brcwcri. 



236. Spizella breweri Cassin. 



BREWER SPARROW. 



Synonyms Spizella pallida, part; Spizella pallida var. brcwcri. 



Status Reported as breeding at Fort Whipple (Coues, i866a, p. 87). and 

 in the Huachuca Mountains (Willard, igoSb. p. 206), and as probably breeding 

 on the Desert of the Little Colorado (Merriam, 1890, p. 96). Tn the northern 

 and central parts of the state it is a summer visitant only, but in the lowlands 

 of southern Arizona it remains in numbers throughout the winter, as is also the 

 case along the Colorado River from The Needles southward (Mus. Vert. Zool.). 



237. Spizella atrognlaris (Cabanis). 



BLACK-CHINKED SPARROW. 



Synonym Spizella evnra. 



Status -There are but few records of the occurrence of this species in Ari- 

 zona. Found at Fort Whipple as a rare summer visitant but common migrant 

 (Coues, i866a, p. 87) ; specimens secured at Mineral Creek in October, and in 

 the Santa Catalina Mountains in February (Scott. 1887. p. 200) ; found breeding 

 in the Hualpai Mountains at 6000 feet (Stephens, 1903, p. 103) ; and noted on 

 one occasion in the Huachuca Mountains in April (Swarth, 1904^ p. 40).
