Hummingbirds are some of the most vibrant and aerobatic creatures witnessed here in the Adirondacks. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in mid-air at wing-flapping rates that vary from around 12 beats per second to an excess of 80 beats per second, the smaller the species the faster the wing flapping.
There are more than 300 species of hummingbirds found exclusively in the Americas from Alaska to Chile and are classified as the smallest bird species. With most of this species measuring 3–5 inches in length and weighing about the same as a penny or .09 oz. The runt of these species is the bee hummingbird that is approximately 2 inches long and weighs less than .07 oz.
