[00:00:00][Music] Every meeting season, the peacock puts on a grand performance for the pee hen.

[00:00:13][Music] He spreads out his spectacular feathers, also known as its train, and ruffles it back and forth so the reds, blues, and greens shimmer in the light.

[00:00:27]If that doesn't please her, he shimies to produce a rattlelike sound for extra effect.

[00:00:35]Unfortunately, this male may have to try harder. Clearly, feathers aren't only used for flying.

[00:00:44][Music] Let's explore fantastic feathers and all that they can do.

[00:00:53]Feathers are made of keratin, a protein that plays a crucial role in forming protective structures in animals, including our nails and hair.

[00:01:07]Here is a rundown of the key roles feathers play.

[00:01:11][Music] [Music] On a bird's body, contour feathers form an interlocking grid that make the surface windproof and in some cases waterproof.

[00:01:34]For instance, ducks and greaves coat their feathers with oil secreted from a gland near their tails to make sure they don't soak up water.

[00:01:59]Some birds are brilliantly colored.

[00:02:04][Music] Others uniformly drab.

[00:02:15]This flamboyant Himalayan monal is a shimmering rainbow in motion.

[00:02:21]It shows off its feathers to attract the attention of a female.

[00:02:28]The brown feathered female though would rather focus on her meal.

[00:02:33]This difference in colors is common among birds. Often the main purpose of a male's bright feathers is to attract a female.

[00:02:43]Whereas female birds, particularly those involved in nesting, have a duller plumage that helps them stay hidden from predators.

[00:02:53]However, not all camouflage is dull.

[00:02:57]Barbets and green pigeons have bright green hues, so they can disappear in the foliage of a tree.

[00:03:08]Feathers are also used to produce song as well as silence.

[00:03:20]The clubwinged mannequin produces an electronic beeplike sound with its wings to woo a female.

[00:03:29]On the other hand, the soft feathers of a barn owl give it an almost noless flight.

[00:03:36]It can fly inches from its prey without being noticed.

[00:03:48]Feathers are designed for flight.

[00:03:56]They are light and flexible but tough so they can withstand the force of wind.

[00:04:04]The wing feathers help produce lift, while tail feathers often spread out like a fan to steer the bird in the right direction.

[00:04:18][Music] The sand's feathers deserve a special mention.

[00:04:25]The sand grouse lives in dry landscapes.

[00:04:30]When temperatures sore, it travels to faraway ponds and lakes, soaks up the water in its belly feathers, and brings it back for its chicks to suck on.

[00:04:42]A single bird can have between 1,000 to 25,000 feathers that differ in size and function.

[00:04:56]Let's explore the main types of feathers. Contour feathers cover the body and streamline the shape.

[00:05:08]Down feathers positioned closest to the chest and belly trap heat and insulate birds from cold.

[00:05:20]Strong and stiff wing feathers, also called remages, power birds forward and upward.

[00:05:30]Tail feathers or rectuses spread out like a fan and help steer birds when in flight.

[00:05:38][Music] Bristles are short feathers found around the neck, eyes, and bill.

[00:05:46]They act as sense organs and also protect birds's eyes and face.

[00:05:53][Applause] As we've seen, feathers are clearly multitasking marvels.

[00:06:00]They serve as water carriers, winter coats, fashionable courtship attire, musical instruments, and more.

[00:06:13][Music] So the next time you see a bird, look closely to identify the different kinds of feathers and take a moment to appreciate all the fantastic things they can do.
