HUMMINGBIRDS

HUMMINGBIRDS. Family TROCHILIDAE

Hummingbirds have been truly called "Winged Gems." They are the smallest of birds, the usual plumage being a metallic green with throat or crown patches of the brightest of iridescent shining red, orange, blue or violet. Their nests are marvels of architecture being compactly and intricately made of plant fibres and downy feathers ornamented in some cases with lichens. Their flight is accompanied by a peculiar buzzing sound produced by their rapidly vibrating stiffened wing feathers. Their food is small insects and honey both of which they get chiefly from flowers.

This species saddles its nest upon branches often at heights of 20 or 30 feet from the ground. They are made of plant down and generally decorated with lichens on the outside, similar to nests of the Ruby-throat. The two white eggs measure .65 x .40.

428. RUBY-THROATED

HUMMINGBIRD. Archilochus colubris.

Range North America east

of the Plains and north to

Labrador.

This is the only representative of the family found

east of the Mississippi. It is

a small species, 3.5 inches

long, with greenish upper

parts and a bright ruby throat. Its nest is as beautiful, if not more so, than that of any other species. They build their nests on horizontal limbs of trees at any height from the ground, but usually more than six feet. Branches an inch or more in diameter are usually selected, they not being particular as to the kind of tree, but oaks, pines and maples perhaps being used the most often. The nests are made of plant fibres and down, and the exterior is completely covered with green lichens so that it appears like a small bunch of moss on the limb. The two white eggs are laid in May or June; size .50 x.35.
