write six flight adaptations of birds
Answers
Answer:
Adaptations for Flight
Birds evolved not only wings, but many other adaptations that make it possible to fly. Feathers provide insulation, waterproofing, and a lightweight means to become airborne. Birds have honeycombed or hollow bones, reducing body weight. And instead of weighty jawbones and teeth, birds evolved a light and serviceable beak made of keratin. Most birds consume energy-packed foods rich in calories – like seeds, fruits, and meat, which add as little as possible to a bird’s payload. And what they eat is processed rapidly, so they aren’t weighed down by waste.
Answer:
Explanation:
THESE ARE MORPHOLOGICAL ADAPTATIONS.
(1)Mobile Neck and Head
The birds have a long and flexible neck which helps in the movement of head important for various functions. They possess a horny beak which helps them to pick the grains and insects while feeding.
(2)Body Contour
The birds have a spindle-shaped body to offer less air resistance during flight. This helps the birds to conserve energy and become more efficient at flying.
(3)Short Tail
The tail bears long feathers that spread like a fan and function as a rudder during flight. They also help in balancing, lifting, and steering while flying and perching.
THESE ARE ANATOMICAL ADAPTATIONS
(1)Digestive System
The birds have a very high rate of metabolism. Therefore, food digests rapidly. The length of the rectum is reduced because of the minimum undigested waste. They have no gall bladder which reduces the weight of the bird.
(2)Warm Blooded
The temperature of the body of a bird remains high and does not change with the change in the environment. This facilitates the birds to fly at very high altitudes.
(3)Respiratory System
The respiratory system of birds is designed in such a manner that the food is oxidised rapidly and a large amount of energy is liberated. Since the metabolism rate is higher, a large number of oxygen molecules are required by the body. For this, the lungs are provided which occupy the entire space between the internal organs.
