Birds are the only animals with feathers. They have two main types. Strong, lightweight contour feathers give birds their coloring and shape. They help the birds steer while flying. Soft, fluffy down feathers give adult birds a layer of protection next to their skin. Down feathers cover the bodies of young birds.

Perfect, a pizza joint! Finally, a little taste of home. But as I sat down to eat, I realized that the crust looked weird, the sauce was merely ketchup, and there were hot dogs standing in for pepperoni. Culinary diversity strikes again!
- Contour lines never cross. All lines on a contour line represent one elevation.- The spacing of contour lines depends on slope characteristics. Contour lines that are close together show a steep slope. Contour lines that are far apart show a gentle slope.- Contour lines that cross a valley or a stream are V shaped. The C points toward the area of the highest elevation. If a stream or river flows through the valley, the V points upstream.-The tops of the hills, mountains, and depressions are shown by closed circles. Depressions are marked with short, straight lines inside the circle that point down slope to the depression.
Contour feathers are long, strong, and smooth, while down feathers are soft and fluffy. Contour feathers give birds their coloring and shape and are used in flight. Down feathers provide a layer of insulation.

Definition: The outer layer of feathers that cover a bird's body, wings, and tail and give the bird its characteristic appearance. Contour feathers differ from other body feathers (such as down and semiplumes) in that they consist of two vanes along a shaft that have interlocking barbs that give strenght and structure to the feather shape
In between contour feathers is a patch of bare skin called the apteria. Down feathers develop in the apteria preserving air trapped under the contour wings. Downy feathers are shaped of a incredibly unfastened structure that is flexible and helps trap air close to the bird.
There are several different kinds of feathers: bristle, semiplume, filoplume, down, feathers with vanes like the contour and flight feathers.
Small, white, down feathers that grow in between flight and contour feathers. They provide insulation for the animals.
