Plumages of Grey Junglefowl Gallus sonnerati Temminck
Facing page 246
The chick in down has very distinct patterns and coloration, and the wing feathers sprout rapidly, so that it can fly a short time after hatching. The juvenile plumage of both sexes resembles that of the adult female, with usually a hint of the sealing-wax spots on the median wing-coverts of the cock. A full-grown cock in the eclipse plumage has the specialised neck hackles replaced with black ones. This partial moult lasts only for three months after the breeding season.

The grey junglefowl (Gallus sonneratii), also known as Sonnerat's junglefowl, is one of the wild ancestors of domestic fowl. Grey junglefowls are endemic to India, and even today they are found mainly in peninsular India and towards the northern boundary.
