Hummingbirds are birds in the family Trochilidae, and are native to the Americas. They can hover in mid-air by rapidly flapping their wings 12–90 times per second (depending on the species). They can also fly backwards, and are the only group of birds able to do so. Their English name derives from the characteristic hum made by their rapid wing beats. They can fly at speeds exceeding 15 m/s (54 km/h; 34 mph).
Hummingbird Feeding
Hummingbirds feed on the nectar of plants and are important pollinators, especially of deep-throated, tubular flowers. Like bees, they are able to assess the amount of sugar in the nectar they eat; they reject flower types that produce nectar which is less than 10% sugar and prefer those whose sugar content is stronger. Hummingbirds meet their needs for protein, amino acids, vitamins, minerals, etc. by preying on insects and spiders, especially when feeding young. Most hummingbirds have bills that are long and straight or nearly so, but in some species the bill shape is adapted for specialized feeding.
