Three Reasons Why Birds Preen  1) To clean feathers  2) To organize feathers  3) To spread oil to keep skin soft and prevent feathers from becoming brittle  1) To clean feathers  2) To organize feathers  3) To spread oil to keep skin soft and prevent feathers from becoming brittle

Flying Paper Birds Types of Flight  Gliding-In gliding flight, a bird's wings deflect air downward, causing a lift force that holds the bird up in the air. When a bird is gliding, it doesn't have to do any work  Soaring-Soaring flight is a special kind of glide, in which the bird flies in a rising air current. Because the air is rising, the bird can maintain its height relative to the ground. (Vultures and Hawks)  Flapping-The wings flap with an up-and-down motion. When the wings move up and down, they are also moving forward through the air along with the rest of the bird.
