Some of the most interesting looking birds out there, peacocks are famous for their big, colourful feathers that are typically green and blue.
The encompassing term for them is peafowl, with peahens being the brown, dull coloured females and peacocks being the impressive colourful males.
The males display their feathers out in a fan to help attract females. This guy was displaying his feathers towards a female at a park in Sri Lanka. There were many peacocks around Sri Lanka, as the Indian Peafowl are common here. Two other subspecies exist, the Congo Peafowl and the Green Peafowl in Burma, which is an endangered species.
