We all know the general features of birds. They have wings, feathers that keep them warm, their bones are light and hollow that makes their bodies light. This is the reason why they are able to fly. They have two legs with claws that help them to climb trees and hold on to the branches. Some water birds have webbed feet that help them to swim. They have beaks and they use their beaks for eating food, catching their prey, and making nests to lay eggs.
How Do Birds Make Their Nests?
It is actually very interesting to know that they make their nests as cozy as your bed. They make their nest with materials such as wool, soft twigs, cotton wool, roots, grass, hair, etc. The birds keep looking for these small things and keep collecting them to make a nest.
Birds make their nest in very safe places. They can actually figure out which place is safe for them. They protect themselves from their enemies like humans, snakes, crows, cats, rats, and squirrels.
Crows make their nests very high on the trees. They make their nests with any kind of materials like wire, wood, etc. Birds like dove make their cozy nests in thorny hedges or between the cactus plants to keep them safe from animals.

Sparrows and pigeons make their nests around our houses.
Koel is a kind of bird that looks like a crow except that it has a beautiful voice. Koels are too lazy to make their own nests so they lay eggs in the crows’ nests and the crows hatch them along with their own eggs.
Barbet birds or coppersmith birds make their nests in the holes of trees.
Tailorbirds make their nests by stitching two leaves of a small tree and then they lay eggs in the fold of the leaves.
Sunbirds make their nests like a hanging basket from the branch of the tree. Their nests are made up of grass, thin twigs, dry leaves, bits of tree bark, and pieces of cloth rags.
Birds normally make their nests to lay their eggs in them. Then they hatch the eggs, raise the chicks and when the chicks learn to fly, they leave the nest. They make nests only to lay eggs.
