Explanation:
Types of Feathers
Filoplume feathers are incredibly small. They have a tuft of barbs at the end of the shaft. Unlike other feathers which are attached to muscle for movement, filoplume feathers are attached to nerve endings. These feathers send messages to the brain that give information about the placement of feathers for flight, insulation, and preening.
Flight feathers are found two places on birds: the wings and tail. Flight feathers are long, and on the wings, have one side of the vane wider than the other. They also have stronger barbules which give them more strength for flight.

Colors In Feathers
Feathers come in every color of the rainbow. Most colors are caused by a pigment, just like food coloring being added to frosting. If you add drops of red food coloring (the pigment) the frosting turns a reddish color. The same works for the color yellow. But there is a problem with the last primary color, blue. In feathers, there is no blue pigment. So how can a Blue Jay appear blue if it has no blue pigments?

So how are green feathers made? Touracos are the only bird that can produce green pigments. All other green birds use a combination of pigments and reflecting blue wavelengths. Can you figure out what color pigment is needed to make green when mixed with the blue wavelengths? If you guessed yellow, you are correct. The wing at the top of this page has yellow pigments but also reflects blue light. This makes our eye see the color green.
Uses Of Feathers
There are so many different ways that birds use feathers that there is no way they can all be listed here. This page will let you know the most common uses and a few that are odd but interesting.
FLIGHT
Obviously, birds use feathers to fly. The long flight feathers help propel the bird through the air, while the contour feathers make the rest of the bird streamline.

WARMTH
During the colder months, feathers help insulate birds to keep them warm. Also, during the hot months feathers can help keep the bird cool. Some birds that live in colder areas, such as Redpolls, have up to 30% more feathers during the winter than summer.
STEALTH
Owls have special serrated flight feathers on their wings that help them fly silently. The serrated edge breaks up the air as it moves over the wing reducing the amount of noise. Ducks and doves, on the other had, have a very smooth leading edge to their wing, and therefore produce a loud whistling noise when flying.

DISPLAYING
Some birds can move their brightly colored feathers in a way that attracts a mate. Peacocks can fan their upper tail covert feathers producing a beautiful bluish green fan. Other birds, such as the Eastern Kingbird, have a stripe of colorful feathers hidden underneath the contour feathers on top of their head. The Eastern Kingbird displays these bright yellow feathers only when trying to find a mate.
SOUNDS
Some birds produce sounds using their feathers. The Ruffed Grouse flaps its wings while standing on a hollow log to produce a drumming sound (and the hollow log makes the sound louder as it echoes inside). Nighthawks and Snipe dive towards the ground and pull up at the last second to produce an unusual ‘growl-like’ sound. This sound is made as air travels quickly over the wing feathers.

DISTRACTIONS
Some birds, like the Dark-eyed Junco, have bright feathers on the outside of their tail which they flash when being chased. They then cover these feathers and quickly turn the other way while trying to lose their predator.
SNOWSHOES
Believe it or not, Ptarmigans (birds that live in the snow) have feathers on their feet that act like snowshoes. These feathers help the birds from falling through deep snow.

CAMOUFLAGE
Some birds don’t want to be seen, so their feathers help them blend in with their habitat. Owls, for example, can easily blend in with bark as they push their bodies up against a tree’s trunk. The Snowy Owl, which lives where there are no trees, blends in perfectly with a wintry scene.
PROTECTION
Feathers help protect the bird’s delicate skin. Without feathers, a bird would be cut badly if it flew into a thick bush. Some birds, such as Hornbills, even have bristle feathers that act like eyelashes which protect the bird’s eyes
