38 PACIFIC COAST AVIFAUNA No. 10 



156. Calypte anna (Lesson). 



Anna Hummingbird. 



Synonym — Trochilus anna. 



Status — A rare autumnal visitant, reported from Camp Grant in September 

 (Henshaw, 1875b, p. 375), from the Santa Catalina Mountains in October (Scott, 

 1886, p. 431), and from the Huachuca Mountains in October (Fisher, 1904, p. 

 80). 



157. Selasphorus platyeercus (Swainson). 



Broad-tailed Hummingbird. 



Syn on y m — Tro cJi ill is platyeercus. 



Status — Common summer visitant in the higher parts of the Transition zone 

 and upward, throughout Arizona ; reported from practically all of the higher 

 mountain ranges visited by collectors : White Mountains, Camp Grant, Santa 

 Catalina Mountains, Mogollon Mountains, San Francisco Mountain, Hualpai 

 Mountains, Huachuca Mountains, Santa Rita Mountains. But one lowland rec- 

 ord : Sulphur Spring Valley (Osgood, 1903, p. 130). 



158. Selasphorus rufus (Gmelin). 



Rufous Hummingbird. 



Synonyms — Poly t nuts rufus; Trochilus rufus. 



Status — During the late summer this species is an exceedingly common mi- 

 grant in the higher mountains of the state. As it appears in numbers early in 

 July it has been occasionally reported as a "summer resident", but it undoubtedly 

 does not breed anywhere in Arizona. Tt is of comparatively rare occurrence in 

 the spring. 



159. Selasphorus alleni Henshaw. 



Allkn Hummingbird. 



Synonym — Trochilus alleni. 



Status — A rare visitant: A male secured in the Santa Catalina Mountains, 

 July 23, 1884 (Scott, 1886, p. 431) ; specimens taken in the vicinity of Bisbee in 

 August and September (Allen, 1893, p. 36) ; and in the Huachuca Mountains in 

 July, in 1896 and in 1902 (Swarth, 1904b, p. 19). These are all the records for 

 Arizona. 



The Allen and Anna hummingbirds probably belong in the same category in 

 their manner of occurrence in Arizona : species that occasionally wander to this 

 exceptional distance only at the period of general dispersal in the late summer. 

 They can hardly be regarded as migrants, following a fixed path to a definite des- 

 tination.
