As Peter Forbes observes, "Human warning signs employ the same colours – red, yellow, black, and white – that nature uses to advertise dangerous creatures."
The Indian peafowl's size, color and shape of the crest make them easily identifiable within their native distribution range. [11] It displays a marked form of sexual dimorphism .
