68. Rufous Humming-bird; Selasphorus rufus (Gmel.). 



Back largely cinnamon red, with but a trace of greenish. Head 

 plain greenish. Gorget coppery red ; sides cinnamon rufous ; belly white. 

 Size small. Apparently resident in the State, but breeds more com- 

 monly to the northward of California. 



69. Allen's Humming-bird; Selasphorus alleni Hensh. 



Very similar to the preceding, females especially alike. Rufous on 

 back largely restricted, the golden green prevailing. The tail-feathers 

 of the rufous humming-bird are very broad, and the second from the 

 middle has a conspicuous notch. In the Allen's humming-bird the tail- 

 feathers are very narrow, the outermost pair being fine and sickle-shaped. 

 A common summer resident over much of the State, but often con- 

 founded with the preceding. 



70. Calliope Humming-bird; Stellula calliope Gould. 



Size very small. No crown ornament. Gorget of narrow elongated 

 feathers, with white bases and metallic violet or lilac tips. Below white, 

 the sides glossed with green. A summer resident of the Sierra Nevada 

 Mountains. 



TYRANT FLYCATCHER FAMILY 



Mostly small, dull colored birds, although two of our species are 

 larger and have bright crown-patches. Colors generally brownish or 

 olive-gray or greenish, characteristically unstreaked. Bill broad and 

 flattened, with large bristles at its base. Feet small. Most species sit 

 very quietly in repose, fluttering from their perches into the air after 

 flying insects. 



71. Arkansas King-bird; Western King-bird; T^rannus verticalis 

 Say. 



A noisy, pugnacious species, aptly called the tyrant flycatcher. 

 Length, eight or nine inches. The back is olive-gray; the head and 

 breast clear ashy; the under parts bright yellow. The tail is black with 

 the outer pair of feathers white on outer web; crown with a concealed 

 patch of scarlet, which is wanting in the young. A common summer 

 resident over most of the State. 



72. Cassin's King-bird; Tyrannus vociferans Swains. 



Very similar to preceding, from which it may at once be distin- 

 guished by the absence of the white outer web of the outer tail-feathers. 

 These feathers are sometimes narrowly edged with whitish or grayish, 

 but never completely so as in the Arkansas king-bird. A southern 

 species, apparently rare north of Los Angles County.
