Many bird species lay their eggs in protected arrays, where the fledglings live inside a warm, cushioned nest.
Some birds build nests from sticks, twigs, and leaves from trees. Other birds will use mud or dirt from the ground mixed with straws or grasses to make their nests. Some even use feathers and fur from animals that they find on the ground, as well as other materials like string and palm leaves.
The future existence of birds is being threatened because humans are destroying their habitats with pollution and deforestation.
We should prepare for a world where birds are extinct, but If we can provide shelter for birds for future generations, then there is a chance that the future of our planet will be altered.
