142 MACROCHIRES: Goatsuckers, Swifts, and Hummingbirds 



RUFOUS HUMMINGBIRD 



(433. Selasphorus rufus) 3 in. 



Male: Back rufous, often washed with green; crown green; 

 gorget metallic coppery red, and sides rusty, otherwise white 

 below; tail pointed, of same color as back. 



Female: Green above; white below with rusty sides and throat 

 copper-flecked; tail white-tipped. Young male like female, but 

 throat brownish. 



Absolute identification is possible only with adult bird in 

 hand. (See Allen Hummingbird.) 



ALLEN HUMMINGBIRD 



(434. Selasphorus alleni) 3 in. 



Male: Crown and back metallic green; tail rufous above; under 

 parts like the Rufous; tail-feathers narrower, pointed, lacking a 

 peculiar notch that characterizes the latter species. 



Female and young: Almost identical with the Rufous. 



Since occasional males have the back almost wholly rufous, 

 while Rufous males often have green-washed backs, absolute 

 identification in the field is impossible. 



CALLIOPE HUMMINGBIRD 



(436. Stellula calliope) 3 in. 



Male: Metallic green above; white below with rusty sides; 

 gorget greatly lengthened at sides, of slender, metallic purplish 

 feathers that give a streaked effect against their white bases. 



Female: Similar to male, but throat finely specked with dark 

 brown, and tail white-tipped. 



Smallest of our Hummers, but a tyrant on his chosen feeding- 

 ground, from which he drives trespassers of other species. 



WHITE-EARED HUMMINGBIRD See Appendix. 



(440.1. Basilinna leucotis) 3| in.
