what are the feathers on top of a peacock's head called
Peafowl The Indian peacock has iridescent blue and green plumage, mostly metallic blue and green. But the green peacock has green and bronze body feathers. In both species females are as big as males but lack the train and the head ornament.[2] The peacock "tail," known as a "train," consists not of tail quill feathers, but highly elongated upper tail coverts. These feathers are marked with eyespots, best seen when a peacock fans his tail. Both sexes of all species have a crest atop the head. The Indian peahen has a mixture of dull grey, brown, and green in her plumage. The female also displays her plumage to ward off female competition or signal danger to her young.
Goose bumps The phrase "goose bumps" derives from the phenomenon's association with goose skin. Goose feathers grow from stores in the epidermis which resemble human hair follicles. When a goose's feathers are plucked, its skin has protrusions where the feathers were, and these bumps are what the human phenomenon resembles.
