-------------------------------------------------------
The peafowl are forest birds that nest on the ground. The Pavo peafowl are terrestrial feeders but roost in trees.

Both species (Blue and Green) of Peafowl are believed to be polygamous. However, it has been suggested that "females" entering a male Green Peafowl's territory are really his own juvenile or subadult young and that Green Peafowl are really monogamous in the wild. The male peacock flares out its feathers when it is trying to get the females attention.

PLUMAGE
Many of the brilliant colours of the peacock plumage are due to an optical interference phenomenon (Bragg reflection) based on (nearly) periodic nanostructures found in the barbules (fiber-like components) of the feathers.

Different colours correspond to different length scales of the periodic structures. For brown feathers, a mixture of red and blue is required: one color is created by the periodic structure, and the other is a created by a Fabry-Perot interference peak from reflections off the outermost and innermost boundaries of the periodic structure.

Such interference-based structural color is especially important in producing the peacock's iridescent hues (which shimmer and change with viewing angle), since interference effects depend upon the angle of light, unlike chemical pigments.
