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- 
Irris, .45 x .30. 
437. Lucifer’s Hummingbird. 
Calothorax lucifer. 
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.
