435. Morcom's Hummingbird. 



Atthis morcomi. 



Range. — This species is known only from a 

 single specimen, taken in the Huachuca Moun- 

 tains, Arizona, in 1896. 



436. Calliope Hummingbird. 



Stellula calliope. 



Range. — Western United States from British 

 Columbia southward, and from the Rocky 

 Mountains west to eastern Oregon and Cali- 

 fornia. 



This is the smallest of North American Hum- 

 mers, being but 3 inches in length. It is greenish 

 above and has a violet gorget showing the 

 white bases of the feathers. They build their 

 nests in all manner of locations from high up 

 in tall pines to within a foot of the ground in 

 slender bushes. The nests are made interiorly 

 with plant down, but the outside is generally 

 grayish colored shreds and lichens. The eggs 

 average but a trifle smaller than those of colu- 

 brift, .45X.30. 



437- Lucifer's Hummingbird. 

 Calothorox lurifer. 



Range. — Mexico, north to southwestern Texas 

 and Arizona. 



This species, which is common in parts of 

 Central Mexico, occurs only casually north to 

 our borders and has not yet been found nesting 

 there. They build small compact nests of plant 

 down attached to the stalks or leaves of plants 

 or weeds. 



438. Reiffer's Hummingbird. Amizilis tzacatl. 



Range. — Abundant in southern Mexico; casual in southern Texas. 



This species is greenish above, with a bronzy lustre; the tail is reddish brown, 

 and the throat and breast are metallic green. They breed abundantly about 

 houses and nest apparently at all seasons of the year in Central America, where 

 they are the most common species of Hummers.
