Animal Kingdom - Nests
In birds, the breeding, hatching and upbringing of the young ones take place at a particular time of the year. It is called the nesting season. Birds build nests for the protection of their eggs and young ones. Generally, the nests are built some time before the birds lay eggs. Birds build different kinds of nests. But birds of a certain species always build a particular type of nest.
In case of human beings, intelligence and some acquired training are necessary for building anything. But the young birds have an inherent wisdom of time of the year, without having received any training from their parents. The inspiration for making a nest is instinctive in birds; it is hereditary and has been passed on from generation to generation. Birds build various types of nests, which are in harmony with their nature and fulfill their needs.

They have an opening on one side with a small hood over it. This opening is used as the entrance. The outer covering of the nest is made up of pieces of the bark of a tree, wickers, and excreta of ants and shells of spider’s egg. Weaver birds woven nest is the most beautiful and a piece of art. It has its unique identity and can be seen on the trees.

Meenrack and hoop make their nests on the projection caves of houses or moulds. They dig the soil by their beaks and remove it with their toes to make a horizontal tunnel with an opening towards a water source. These tunnels are several feet in length. They are cylindrical like an egg chamber with an opening at the end.
Quail, tern ad wild hen etc. make their nests on the ground by spreading grass or leaves on rags, straw, husk or peels.
