Loud, harsh, repetitive 'may-AWE' screaming call, audible over great distances. Display calls are a mewing 'aaaow'. Peacocks call persistently at dawn and before rain.

Indian Peafowl
The Indian peafowl is the national bird of India and one of the most spectacular birds in the world. The peacock's enormous train, which can span over two meters, is used in elaborate courtship displays where the feathers are fanned and vibrated. Despite their size, peafowl can fly short distances and roost in tall trees.
