Explanation:
Bird conservation is a field in the science of conservation biology related to threatened birds. Humans have had a profound effect on many bird species. Over one hundred species have gone extinct in historical times, although the most dramatic human-caused extinctions occurred in the Pacific Ocean as humans colonised the islands of Melanesia, Polynesia and Micronesia, during which an estimated 750-1800 species of bird became extinct.According to Worldwatch Institute, many bird populations are currently declining worldwide, with 1,200 species facing extinction in the next century. The biggest cited reason surrounds habitat loss. Other threats include overhunting, accidental mortality due to structural collisions, long-line fishing bycatch, pollution, competition and predation by pet cats, oil spills and pesticide use and climate change. Governments, along with numerous conservation charities, work to protect birds in various ways, including legislation, preserving and restoring bird habitat, and establishing captive populations for reintroductions.
The bird is a flying feathered creature, with two strong wings and two legs. It can fly in the sky and travel long distances in the air. It builds nest on the trees, and eats insects, fish, grains, etc. Some of the birds have a crest on their forehead. Its tail helps it to keep balance in the air, and the two legs for hopping. It lays eggs, and hatches the young ones.
There are migratory birds which fly from one country to another over the hills, lakes and oceans during some particular season. There are various species of birds, some smaller and some bigger in size. They are of various colours. The tiny birds fly in flocks. The bigger size birds like eagle or the long necked cranes are fond of fish.
They are seen generally near the rivers or marshy lands, waiting to catch fish. The vultures are fond of flesh of dead animals. The owls can see even in darkness. The bats hang from the branches of trees upside down. The bats are actually mammals and not birds, although they resemble birds. Some of the beautiful birds are trained in cages by men.
