About The Broad-billed Hummingbird

Broad-billed Hummingbirds are considered a small hummingbird. Their average length is 8.25 - 10.2 cm (31/4 - 4 inches) long, with a wingspread of approximately 12.7 cm (5 inches). The males weigh about 3.7 grams (0.125 oz), while the females are a little lighter at 3.4 grams (0.1 oz). Broad-billed Hummingbirds have a bright red bill with a black tip. The adult males have metallic green bodies, vibrant blue throats, white undertail coverts and black forked tails. The adult females have metallic green upper parts and grayish throats and undersides. Their tails have pale outer tips. Most distinguishing about the female is the thin white spot behind her eye.

The method in which hummingbird wings are attached to the shoulder allows the wings to move in various angles, enabling the hummingbird to hover, fly straight up, sideways, and even backwards. This unique method of flight requires large flight and pectoral muscles, which weigh about 30 percent of their body weight. The hummingbird's wing beat is approximately 70-75 beats per second (Page and Morton 1989; Sayer 1997; Terres 1980).

Range mass: 3.4 to 3.7 g.

Other Physical Features: endothermic ; bilateral symmetry
