Question

List of new aerial adaptation in birds

Answer 1

Explanation:

Previous (Adansonia)Next (Adaptive radiation)

A biological adaptation is any structural (morphological or anatomical), physiological, or behavioral characteristics of an organism or group of organisms (such as species) that make it better suited in its environment and consequently improves its chances of survival and reproductive success. Due to individual phenotypic plasticity (variability), individuals will be more or less successful. Some adaptations may improve reproductive success of the population, but not a particular individual, such as seen in altruistic behavior in social insects.

Answer 2

Answer:

• In birds, the forelimbs are modified into wings for flying. Hind limbs are adapted for perching, walking and running.
• Bones are hollow with air cavities which keeps the body light.
• Body is streamlined to reduce resistance of air during flight.
• Exoskeleton is made up of feathers which are crucial for flight.
• Lungs have air sacs which helps to maintain buoyancy during flight.
• Cerebellum is well developed for equilibrium.
• Urinary bladder is absent.
• Females have only one ovary and oviduct (left) to reduce body weight.
• Mouth is without teeth.
