Abstract

The hummingbirds (of order Apodiformes) are very small birds, mostly with iridescent plumage. Their ‘wrist and hand’ wing articulation derives lift on both the up- and down-strokes, permitting stationary, upward and reverse hovering. They subsist on flower nectar, tree sap and small insects.
