Hummingbird

Size: Among the smallest birds in the world, most measure 7.5–13 cm (3–5 in) in length. The tiniest, the bee hummingbird, is just 5 cm long and weighs less than 2 g

Appearance: Slender bodies, long narrow beaks, and often iridescent plumage that shimmers in sunlight—brilliant greens, blues, purples, reds, and pinks1.

Wings: Capable of hovering in place, flying forward, backward, and even upside down. Wingbeats range from 12 to 99 beats per second, producing the signature “humming” sound
