I am a breeder of parrots, peacocks, doves, macaws, and other birds. When I was playing and feeding them, I always ended up asking myself, Do all birds have feathers? Why do birds have feathers instead of skin or fur.
Yes, almost all birds have feathers, such as garden birds, backyard birds, wild birds, woodland birds, domestic birds, pet birds have feathers because feathers are common and necessary features for birds, which enables them to fly, fight, fright.
Why Do Birds Have Feathers?
Why do birds have feathers instead of fur like a bear or skin like us, or scales like a fish , Let’s know why feathers matter so much in-depth. Feathers have passed from ancestral birds to modern birds of today.
Birds are expected to be the last remaining representatives of a group of feathered dinosaurs. These feathered dinosaurs had feathers million years ago and it has been passed on to modern birds today. It is expected that feathers evolved long before birds began to fly. Therefore, birds have feathers.
The Birds have Feathers to play the following Role:
To attract females, male birds unfold their colorful feathers and feathered wings. To ward off predators from them and their nests unfold birds show different bright colored feathers.
The feather can be used for communication, many bird species use their feathers to “talk,” especially when looking for a mate. For example, peacocks show their tails to demonstrate their superiority, dominance, and health to females, the brighter and stronger the feathers, the fitter the bird. Therefore, we now know why do birds have feathers of different colors.
Why Are Feathers So important To Birds?
Feather plays the following important roles which are necessary for survival
- Migration for food and breeding.
- Display colors to attract female birds and to frighten the predators.
- Feather is helpful in competition for mating.
- Camouflage in the surrounding environment.
- Thermal insulation against bad climate.
- Water-repellent while swimming and deep diving.
- Water can be stored in feathers of birds that live in the desert(Male sandgrouse).
Which Bird Have Feathers?
All birds like dove, haw, macaw, kingfisher, finches, corvids, hummingbirds, and penguins have feathers, and the only animals that have feathers are birds. Feathers provide protection, heat and cold insulation, serve as a waterproof sheath, help to fly, and attract mates as well.
Types of Feathers
|Sl. no||Types of flight feathers||The Location of a feather.||The function of a feather.|
|1||Primary feathers||at the tip of the wing||provide thrust.|
|2||Secondary feathers||closer to the body, attach to the forearm portion||provide lift.|
|3||Contour feathers||found on the body,||Provide a smooth aerodynamic surface for efficient flight.|
What are Bird Feathers used For?
Birds use feathers for the following functions and reasons.
Insulation against cold and heat: Feathers increase and help insulate birds and keep them warm during the winter months, and feathers also help by cooling in summer. Redpolls, for example, have up to 30 percent more feathers in winter than in summer.
Sound can be produced by feathers: When owls fly on the wings with serrated flight feathers, they make them fly quietly. During a flight in ducks and doves, the smooth leading-edge feather on the wing creates a loud echo.
Male club-winged manakins birds rub their complicated wing feathers together at super-high speeds like crickets, making a violin-like sound like in this vibration. which they do to communicate with other birds.
Did you know that the Uropygial gland or preen gland located at the base of the tail allows birds to make feathers waterproof and flexibleNot only does their plumage keep them warm, but in many situations, the feathers of birds often serve as waterproof coats. The water-repellent feathers are very helpful in deep diving birds and swimming birds.
Why do Birds have Feathers of different Colors? The birds have feathers of different colors to attract females and also to frighten their predators.
Feather plays a role to avoid predators and to catch prey: Some birds, like many other members of the animal world, have natural color in their feathers to camouflage in their surroundings. This helps them passively escape possible predators and also to approach their prey as near as possible.
For instance, parrots normally have green feathers that mix with the surrounding environment such as trees, so by camouflaging with its environment, it can passively escape its predators and can also capture prey such as insects.
Feathers are used to display different colors in males and females: Birds are more dependent on their vision, as colors on feathers help them to choose a mate( also to choose ripe fruits, berries easily) in color display among many male birds.
Why do Birds look so Beautiful? The answer lies in their numerous feather types with varying vibrant color combinations. For instance, A peacock unravels his iridescent train to attract a peahen.
Feathers are useful in Flight as it Aids in aerodynamics when running and flying: Feathers offer the potential for modern birds to fly into the sky. Birds use feathers for flying. The long flight feathers help propel the bird through the air and the contour feathers make the rest of the bird streamline.
From the world’s biggest bird-like ostrich to the smallest birds like the hummingbirds all birds have feathers, Irrespective of whether they can fly or don’t fly, wild or domestic or kept in captivity, swimming or non-swimming birds, all birds possess feathers.
Even though birds like the Chickens, turkey, and ducks lost their ability to fly after being raised by mankind, they still possess feathers because feathers are basic features of birds.
Birds are expected to be the last surviving members of a group of feathered dinosaurs that lived 150 million years ago because fossils of this time show evidence of bird-like dinosaurs with feather and winged bodies.
Archaeopteryx, which defines the relation between birds and dinosaurs, is a significant fossil of an animal similar to dinosaurs and birds. Archaeopteryx’s fossilized skeleton looked like that of a dinosaur, as it had teeth, while birds did not, but it had feathers modified for flight as well.
There are fossils of earlier feathered dinosaurs, but the feathers do not have the flight feather characters much. Therefore, It is expected that feathers evolved long before birds began to fly.
In bird-like animals, feathers are evolved million years ago and adopted for flying, feathers are a defining feature for flying, Thus we can say all modern birds have feathers , But which may vary from species to species and also varies in structure and function according to their habitats like the variation in water repellent trait, color, length, and sound production.
Some feathers are more water repellent than others, some are colorful than other, Which is used to help to fly, fight, fright the predators, and attract mates and Feathers are one of the fundamental characteristics of birds, including other features such as a warm-blooded, toothless beak, hard-shelled egg-laying, high metabolic rate, and hollow-bone skeleton.
Birds have feathers to perform different functions like flying, swimming, diving, thermal regulation, etc. Feathers can be as simple as hair like structures to most complex flight aiding structures and colorful to attract mates. Birds are the only species with feathers and these feathers often weigh more than the Skeleton of a Bird.
