432 — 433 — 434 
432 . Broad-tailed Hummingbird. 
Selasphorus platycercus. 
Range.— Rocky Mountain regions, north to 
Wyoming; winters south of the United States 
This species is similar to the Ruby-throat, 
but larger and with the back more golden 
green color, and the throat shining lilac. They 
are very abundant in Colorado and Arizona, 
nesting as do the Ruby-throats in the east, and 
their nests being similar in construction and 
appearance to those of that species. The 
eggs cannot be distinguished from those of 
other species. 
433 . Rufous Hummingbird. 
Selasphorus rufus. 
Range. — Western North America, breeding 
from the Mexican border north to Alaska and 
fairly abundant in most of its range. 
A handsome little species with the back and 
tail reddish brown, and with a throat gorget of 
orange red, the feathers being slightly length- 
ened into a ruff on the side of the gorget. They 
nest in a great variety of locations and at a 
low elevation, such as vines, bushes and the 
low hanging branches of trees. The nest is 
made of vegetable fibres covered with cob- 
webs and often with lichens. The eggs do not 
differ from those of the other Hummers.
