Answer:
1. Since beaks are mainly used for feeding, the variation in beak shape and size mostly has to do with the food that each species prefers. Some beaks are made for digging seeds out of shells while others are designed to dig deep into the ground to pull out prey items. Let's explore some of the most interesting beaks.
2. (1) Sparrow has a small conical beak.
2. Crow has a small slender beak.
3. Parrot have hooked beak
4. Kingfisher has a slender beak.
3. A talon is the claw of a bird of prey, its primary hunting tool. The talons are very important; without them, most birds of prey would not be able to catch their food. Some birds also use claws for defensive purposes.
4. The wing flight feathers are also called remiges. Flight feathers are the longest feathers, like the long, stiff ones you find on the ground. Wing feathers are asymmetrical while tail feathers are mostly symmetrical. Their structure and size allow birds to cut, twist, and turn through the air with ease.
5. This passerine bird is typically found in open farmland, scrub, forest edges, and gardens. Tailorbirds get their name from the way their nest is constructed. The edges of a large leaf are pierced and sewn together with plant fiber or spider silk to make a cradle in which the actual nest is built.
6. Nests provide a safe place for eggs and young birds to develop. Bird nests are extremely diverse, although each species typically has a characteristic nest style. Some birds do not make nests at all and instead lay their eggs in a simple scrape in the ground.
7. Hollow bones are also called pneumatized bones, meaning they're filled with space for air. It is thought that this structure helps with oxygen intake during flight. Air sacs are attached to the hollow areas in a bird's bones. ... This adds more oxygen to the blood, providing a bird with extra energy for flight.
8. The most common type of webbed foot found in ducks, geese, swans, gulls, terns, and other aquatic birds are known as palmate. Palmate means that three toes are completely webbed, enabling efficient propulsion in water. However, only the front toes are connected, while the toe at the back is separate.
9. The beaks of ducks and swan are broad and flat like a spoon. There are tiny holes on either side of the beak. Ducks and swans find their food in the water.
