Detailed explanation-1: -The shape and size of beak of birds depend on their feeding habit.
Detailed explanation-2: -Skin and Feathers. Birds have a sensitive skin that allows them to feel and sense pressure, heat, and cold. The feathers of a bird grow from the inner layer of skin (the dermis). Feathers provide assistance in flight, insulation from cold, waterproofing, and-in some cases-camouflage.
Detailed explanation-3: -Friedman and colleagues discovered that while the thickness of a bird’s beak was related to how they foraged and what they ate, climate also played a role in shaping honeyeater beaks. Honeyeaters such as the Black-headed Honeyeater that inhabit colder regions of Australia had shorter beaks than their relatives.
Detailed explanation-4: -Feathers. High metabolism. A four-chambered heart. A beak with no teeth. A lightweight but strong skeleton. Production of hard-shelled eggs. 05-Dec-2021
