Hummingbirds are small birds native to Americas and belong to biological family Trochilidae. Most species measuring 3 to 5 inches (7.5–13 cm) in length. The smallest bird is the Bee Hummingbird about 2 inches (5 cm) and weighs less than 0.07 oz (2.0 g). The largest hummingbird is the Giant Hummingbird 9.1 inches in length (23 cm) , weighing 0.63–0.85 oz (18–24 g). The Hummingbird’s diet includes nectar, sap, insects, spiders, and sugar water (human supplied). Hummingbirds sleep perched or enter a state of torpidity, which is a state similar to hibernation and slow their metabolic rate to 1/15 of its normal rate. Hummingbirds get their name from the humming sound produced by their wings beating at 70 beats/sec when flying, and they also chirp.

Hummingbirds are credited with never forgetting the flowers that they’ve visited and when nectar is available. This is important since they must feed regularly and frequently.

Male Hummingbirds are territorial and protective of nesting sites and feeders, often chasing other birds away. However, they will accept a familiar human. The presence of only two males may set off aggression whereas a flock would not. The sugary drinks help to sustain these fabulous creatures as they prepare for migration.
