The ability of flight sets birds apart from many other creatures. While insects, bats, and even some gliding squirrels and fish can take flight into the air, none of them can match the speed, agility, and strength of birds. Some birds can fly as fast as 55-65 mph, which is the speed of a car on a highway. The Peregrine Falcon can reach speeds up to 200 mph in a dive! Some birds, like the American Woodcock, fly as slow as 5 mph. And then there are hummingbirds, which have the special ability of hovering in one place while searching for or consuming food.
While not all birds fly, they can still be quite speedy. Penguins are thought to be the 鈥榝lyers鈥 of the ocean. Gentoo Penguins move at speeds of up to 22 mph underwater. The Ostrich is the largest of all land birds, and is known to reach running speeds of up to 60mph. Without a doubt, birds are strong and fast movers.
We all know that not all birds look alike. Birds look so different because over a long period of time they have adapted to use their environment. Think about an and a Turkey Vulture. All birds have wings, but the way they look and the way they are used changes based upon the need of the species. Emperor Penguins need to quickly dive underwater, so their wings are stunted like flippers. A Turkey Vulture needs to soar high in the sky, so it has large, wide wings to ride air currents.
In this activity, kids build paper airplanes that correspond to the four different major wing shapes, based upon the need of the bird.!
Difficulty: Easy
Active Soaring Wings: These wings are longer and narrower compared to the body size of the bird. These birds depend on wind more than thermals to soar, and can fly for longer distances without flapping compared to all other wing types. Birds you may know with Active Soaring Wings are the Laughing Gull and Wandering Albatross鈥攁 bird with a wingspan up to 12 feet, which can eat and sleep while flying, and flies 10,000 miles without stopping.
Difficulty: Medium
Passive Soaring Wings: What does passive mean? It describes things that use little to no energy, like a raptor's wings. Long, primary feathers help birds to catch and soar atop thermals (currents of warm air rising upwards from the Earth). Some birds that have Passive Soaring Wings are the Bald Eagle and the Turkey Vulture. These birds soar for long distances looking for prey.
Difficulty: Medium
High-Speed Wings: These wings are long and thin, but less long than Active Soaring Wings. These wings can create higher speeds than can be sustained by birds' continued flapping. Common birds with these wings are the Forster鈥檚 Tern and the Peregrine Falcon (which can reach dive speeds up to 240 mph).
Difficulty: Hard
Elliptical Wings: These wings are great for creating short bursts of speed, but the momentum cannot be maintained. This causes the birds to flap hard and flap often. Birds you may know with Elliptical Wings are the Northern Cardinal and the American Crow.

约炮视频 New York鈥檚 is a place-based environmental education program that promotes awareness and appreciation of nature through the study of birds. For the Birds! started in New York City in 1997 and provides not only knowledge of local species and habitats, but also encourages a sense of pride in one鈥檚 own community and empowers students to take an active interest in protecting their local environment.
