Black-Chinned Hummingbird (Archilochus alexandri)...The Black-chinned hummingbirds are small - the mature adults are only 3 inches in length. The male Black-chinned has a metallic green back and crown, white underparts with greenish flanks, and an entirely black forked tail, face, and chin. His upper throat is black, but his lower throat and gorget are iridescent purple. His bill is long, straight, and thin. The female Black-chinned also has metallic green back and crown, white underparts with greenish flanks. She has a white chin and throat that has variable amounts of thin dark streaking, and no throat patch. Her tail is dark and rounded, with white tips on the outer feathers. The juvenile Black-chinned hummingbirds are identical to the adult females. Bird watchers are cautioned that the female Black-chinned are very similar to the female Ruby-throated hummingbirds. So much so that the only sure way is differentiate the two is in the hand.
Only the female Allen's hummingbird raises the young. She constructs a well camouflaged nest in a protected location in a shrub or tree using plant fibers, lichens, and spider webs. She lays two white jelly-bean sized eggs, which she will incubate for 13 to 16 days. The young will leave the nest about 21 days after hatching. Amazingly, she will continue to feed the fledglings for several more weeks, then the young are left to fend for themselves. They are known to have two and occasionally three broods each year. Because of their small size, they can be vulnerable to animals and larger birds.
