The nominal race of Slaty-headed Parakeet (above) is native to the western foothills of the Himalayas
(India, Pakistan, Afghanistan south Tibet). It is one of the Ring-necked species of parakeets and one of the few parrots to undertake
seasonal migration (lower down mountain in winter, higher in summer).
The subspecies or related species Finsch's Slaty-headed (below), also called Finsch's or Grey-headed Parakeet
(Psittacula himalayana finschi or P. finschi), inhabits southeast Asia. Both have the slate-grey head
after which they are named and the male has a narrow black border with a blue-green nape.
The long tail has blue feathers with yellow tips (more violet-blue in the smaller Finsch's subspecies which is also a slightly lighter,
yellower green body/wings) and both male and female have a red upper beak fading to orange and an orange lower beak.
