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 lengthened
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 cobwebs and often with lichens. The eggs do not differ from those
of the other Hummers.

Range.--Pacific coast from British Columbia southward; most abundant in
California. Winters in Mexico.

This species is like the last, but the back is greenish, only the tail
being reddish brown. These birds generally locate their nests at low
elevations near the end of overhanging branches, on vines, weed stalks,
or bushes, but have been found as high as 90 feet above ground. The
nests of this species are made of plant fibres and cobwebs, generally
decorated with lichens. The two white eggs measure .50 x .32.
Data.--Santa Monica, Cal., May 29, 1896. Nest two feet from the ground
in a sage bush. Collector, W. Lee Chambers.
