As the name suggests, a parakeet with a gray head. Inhabits open forests, but where protected, can also be found in plantations, gardens, and farm edges. Essentially identical to Slaty-headed Parakeet but does not overlap in range. Male has a dark gray head bounded by a thin black collar which widens and curves up at the throat, forming a round-cheeked appearance. Female has a much paler gray head without the collar. Both sexes have bright red bills, overall green plumage, and long, blue-tipped tails.
