flamingos & peacock

Two of the most astonishing creatures on earth.

Peacock: it is the national bird of India. It has been proved that many of the brilliant colors of its plumage are due to an optical interference called "Bragg reflection", sort of an optical illusion.

Flamingos: the color of their feathers comes from the beta-carotene based diet. Flamingos eat mainly shrimp, which is rich in beta-carotene. The color of a healthy and well fed flamingo is vibrantly bright pink. The white or pale pink color of their feathers is a clear sign of bad diet or illness. This often occurs in captivity.
