Hummingbirds are amazing flyers. They are one of the few animals that can hover, which means remaining in one place in the air without moving forwards or backwards, up or down. To do this, they have wings shaped to the purpose and really strong muscles. And they flap their wings really fast—faster than any other bird at up to 70 wingbeats per second. That adds up to more than 4, wingbeats per minute!
In this activity, kids see if they can flap their arms as fast as a hummingbird flaps its wings. All you need is a stopwatch. First, have your child or children hold their arms out like wings.
Hummingbirds and insects have converged on the same solution: by using their muscles efficiently, they can produce a large amount of power with fast but small movements. Indeed, Hedrick wants to see whether larger hummingbirds, such as the Patagonian giant hummingbird Patagona gigas — which is bigger than the ruby-throated one — move in the same way.
But whereas the ruby-throated hummingbird is common in eastern North America, its larger relative sticks to the Andes mountains in South America. Stolpe, M.

Yong, E. Hummingbird flight has a clever twist. They flap their wings even faster during the courtship display dives used by the males of some species. Moreover, hummingbirds can fly very fast, routinely attaining speeds of 20 to 30 miles per hour.
As a result, mosquitoes have to flap their wings about times per second, much more than scientists would expect for an insect their size. The power needed for faster wing strokes increases exponentially—a huge energy suck that mosquitoes compensate for by, well, a lot of blood-sucking.
What do mosquitoes look like? Because they are in the same family as the fly, mosquitoes have two wings. They also have hair-like scales that cover their bodies and a long proboscis.
Yellow fever mosquitoes, on the other hand, have bright whitish-markings down their legs. Flying nonstop for 18 to 20 straight hours, the ruby-throated hummingbird crosses the Gulf of Mexico to reach breeding grounds in the eastern United States. Climate change is causing widespread shifts in hummingbird migration. If flowers bloom early, before the hummingbirds reach them, then the birds face starvation. 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 to agriculture, primarily cattle ranches, and therefore unsuitable for the birds.
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 bigger to allow them to form and lay eggs. The duller coloring protects her while incubating eggs. 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 tiny eggs.
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.
The sword-billed hummingbird is the only bird with a bill longer than its body. 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 minutes. They 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 pounds of meat a day.
