several on record); but it is very improbable that it breeds in Transition or 
below. (See J. Grinnell, Condor, m1, 1901, p. 128.) 
264 (434) Selasphorus alleni Henshaw 
ALLEN HUMMINGBIRD 
Synonyms—Trochilus alleni; Trochilus rufus, part; Selasphorus rufus, 
part; Selasphorus ruber, part. 
Status—Common summer visitant to the humid coast belt (Transition and 
high Upper Sonoran zones). Breeds south through the San Francisco Bay re- 
gion and Santa Cruz district at least to middle Monterey County; also at Santa 
Barbara (Jeffries, Auk, v1, 1889, p. 221; Bowles, Condor, xiv, 1912, p. 77), and 
at Santa Paula, Ventura County (Willett, Pac. Coast Avif. no. 7, 1912, p. 61) ; 
also on San Clemente, Santa Catalina and Santa Cruz islands where resident 
throughout the year, these being the only localities in the state where the species 
winters regularly. Occurs commonly as a spring migrant through the lower 
parts of the San Diegan district, where it arrives early: January 26 at San 
Diego (Torrey, Condor, x1, 1909, p. 173). In its southward movement, it appears 
in midsummer along the higher mountain ranges, at least from Mount Pinos 
southeastward. The easternmost record in northern California is Mount San- 
hedrin (Stone, Proe. Acad. Nat. Sei. Phila, 1904, p. 582). The Allen Hum- 
mingbird is thus confined both as a migrant and breeding bird to a relatively 
narrow coastal area the full length of the state. 
265 (436) Stellula calliope (Gould) 
CALLIOPE HUMMINGBIRD 
Synonyms—Trochilus callione; Selasphorus calliope; Callothorax calliope; 
Atthis calliope. 
Status—Common summer visitant to upper Transition and Canadian zones 
along the entire Sierra Nevada, north through the Shasta region; thence east to 
Warner Mountains, Modoe County (Mus. Vert. Zool.) and west to Wildeat Peak, 
Siskiyou County (Mus. Vert. Zool.) ; south through the Mount Whitney region, 
and in southern California from Mount Pinos to the San Bernardino Moun- 
tains (J. Grinnell, Univ. Calif. Publ. Zool., v, 1908, p. 72). Recorded in adja- 
cent country during migration, casually west to San Francisco Bay: Oakland 
(Mus. Vert. Zool.), Haywards (Emerson, Zoe, tv, 1893, p. 179), and Berkeley 
(Belding, Land Bds. Pae. Dist., 1890, p. 89). The breeding records from the 
coast region are very probably erroneous. As before stated, the facts that when 
one or two species of hummingbird are nesting, other species may be passing 
through the region, and that females of the different species are similar to one 
another in general appearance, have undoubtedly led to misidentification in a 
regrettably large part of the literature relative to the hummingbirds of Califor- 
nia; for instance in Bendire’s Life Historics. The Calliope hummingbird seems 
to be adherent to semi-arid Transition and Boreal (hence interiorly), and its 
range is thus in a way complementary to that of the Allen hummingbird of the 
coastal region.
