Hummingbirds hum, but the sound isn't from their voices. The hum comes from their rapid wing movements — the smaller the hummingbird, the faster the wingbeat. A hummingbird beats its wings between 10 and 80 times per second during direct flight.2 During courtship dives, wingbeats reach 200 per second. The males angle their wing and tail feathers du...
Hummingbirds can fly not only up and down but sideways and even upside down. They beat their wings in a figure-eight pattern similar to insects, making them the only vertebrates capable of sustained hovering. The average speed of hummingbirds is 26 mph, with a much slower 2 mph used between flowers.4 Astonishingly, some males reach speeds of 55 mph...
Most hummingbird species migrate and do so alone. Contrary to the urban legend, they don't hitch rides on migrating Canada geese. Rufous hummingbirds migrate the longest distances, flying 4,000 miles from Mexico to Alaska every year.6 Flying nonstop for 18 to 20 straight hours, the ruby-throated hummingbird crosses the Gulf of Mexico to reach breed...
Cuba's bee hummingbird is the smallest bird in the world. It is around 2 inches long and weighs less than a dime at only 2 grams. Unsurprisingly, their nests are similarly miniature, around the size of a quarter, while their eggs are the size of coffee beans. IUCN lists the bee hummingbird as near threatened. Much of its habitat has been converted ...
Males have brighter-colored plumage to attract a mate. They have other adornments as well. The tails of species like the long-tailed sylph (Aglaiocercus kingii) are so long that the male bird has great difficulty flying. Only a strong, healthy male comes into a breeding state with a very long tail, and females know it. Female hummingbirds are bigge...
Hummingbird nests usually don't exceed the size of a walnut, but they stretch to accommodate growing birds. The female bird weaves velvety cups from moss, leaves, and fuzzy plant parts like cattail using spider silk. Once the nest is formed, she uses the silk's stickiness to attach lichen and moss to camouflage the nest before laying one to three t...
One of the hummingbird’s hallmarks is its long, narrow bill that's specialized to fit into tubular flowers. The shape suits their preferred nectar source, with some dramatically curved and others very long. To catch insects, the lower half of the bill flexes downward when opened. The fully opened bill then shuts around the insects like a snap trap....
To keep the fastest metabolism in the world fueled, hummingbirds need a prodigious amount of food. They eat half their body weight in sugar daily through meals every 10-15 minutes.11They also eat tree sap and insects. A hummingbird can eat hundreds of fruit flies each day. If an average-sized man had a hummingbird's metabolism, he'd need to eat 285...
Hummingbirds' tongues are as long as their bill and coil to fit in their mouth. The tongue is split and has fine hairs called lamellae. Once inside the flower, the tongue separates, and the lamellae curl inward. The bird flicks its tongue at speeds up to 17 licks per second.12This curling and fast licking create a micropump that traps the nectar on...
One study found that the hummingbird’s hippocampus is significantly larger, relative to telencephalic volume, than any bird examined to date.13Why? Because they need to know which flowers they visited to collect nectar. Hummingbirds remember the quantity and quality of nectar, when they visited the flower, and where it is located. This allows them ...

Animals Network Team. Hummingbirds are charismatic, zippy little creatures that typically subside on the nectar of flowers. Because they are so speedy, and their metabolism matches their speed, they must eat virtually constantly. These little birds, native to the Americas, are incredibly unique and specialized.
