Is the peacocks endangered

Yes, the Indian Peafowl is endangered and the Green Peafowl is nearly, if not absolutely, extinct.

The peacock population is dwindling fast due to habitat loss, contamination of food sources and poaching. Ironically, until today no census has been conducted of the peacock. Non-feasibility has been cited as the only reason. The sole stock-taking of the peacock population in India was done by WWF India in 1991. It revealed that India was left with only 50 per cent of the total peacock population that existed at the time of Partition in 1947. While the green peacock is already believed to be extinct, the peacock may soon end up on the critically endangered list.
The green peafowl is endangered in its native habitats.

Peafowl - a species of pheasant native to southern Asia - come in many colours and varieties, and are frequently raised by humans. They do well in captivation, and adapt to man's environment very well.
