44 PACIFIC COAST AVIFAUNA No. 10 



185. Camptostoma imberbe Sclater. 



BEARDLESS FLYCATCHER. 



Synonym Ornithion imbcrbc ridgwayi. 



Status A rare summer visitant, known to occur in only a limited area in 

 the Santa Cruz Valley, in the vicinity of Tucson. The conditions apparently re- 

 quired by the species, dense growths of tall timber, are met with in Arizona at so 

 very few points, at the low altitudes frequented by the species, that its known 

 range will probably not be greatly extended in the state. 



186. Otocoris alpestris leucolaema (Coues). 



DESERT HORNED LARK. 



Synonyms ( ?) Otocoris alpestris, part; (?) Eremophila corniita, part; 

 Eremophila alpestris var. chrysolaema, part; Otocorys arcnicola, part; Otocoris 

 alpestris arcnicola, part; Otocoris alpestris enthymia. 



Status Common winter visitant. There are numerous winter records of 

 horned larks from the northern and central portion of Arizona, some of which are 

 known to pertain to this subspecies, and others that probably do so. 



187. Otocoris alpestris adusta Dwight. 



SCORCHED HORNED LARK. 



Synonyms Eremophila alpestris chrysolaema, part; (?) Otocoris alpestris 

 chrysolaema, part ; Otocoris alpestris aphrasta. 



Status Common resident on the plains of extreme southeastern Arizona, 

 from the west side of the Santa Rita Mountains (Swarth, 19053, p. 79) east to 

 Fort Bowie (Bendire, 1895, P- 345)- North to Tucson and Oracle. Other

SONORA HORNED LARK. 



Synonyms Otocoris alpestris arcnicola, part ; Otocoris alpestris leucansip- 

 tila.

MONTEZUMA HORNED LARK. 



Synonyms nremophila cornuta, part; Eremophila alpestris chrysoiacma.

 There are breeding records from San Francisco Mountain, Fort Verde, and the 

 Little Colorado River (Oberholser. 1902, p. 855). In the Mogollon Mountains 

 it has been found breeding up to 10,000 feet (Mearns, i8ox)a, p. 256). Local- 

 ities at which it has been found at other seasons are Pima County, Wilcox, San 

 Pedro River, and Fort Huachuca.
