Characteristics of Birds
1) Endothermic (warm blooded)
2) two wings
3) two legs
4) covered mostly with feathers
5) Bill or beak
6) Lay a hard-shelled egg
How Birds are Adapted for Flight
Strong, light skeleton
Tail vertebrate joined for stability
High-energy diet
Strong, efficient heart
Specialized lungs connected to air sacs
Functions of Feathers
Down Feathers (4 characteristics)
Contour Feathers (4 characteristics)
Trap warm air near body
Give birds streamlined shape
Under contour feathers of adults
Barbs branch off main body
Cover bodies of some young birds Colors attract males
Fluffy
Camouflage protects from predators
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

How Bird Wings Work
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.
Bird Paper Airplane Types
