In India, they are distributed in the states of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Uttar Pradesh and Punjab.The Important Bird and Biodiversity Area (IBA) of the black-headed jay species in Nepal are Annapurna Conservation Area, Phulchoki Mountain forests, Langtang National Park and Bardia National Park.
Ecosystem and habitat
These black-headed jay species have moderate forest dependence. They normally occur in altitudes from 1,500 to 3,000 meters. The artificial ecosystems and habitats of these species include agricultural lands.The natural ecosystems and habitats of these species include tropical and subtropical moist montane forests, pine-oak forests and tropical and subtropical high altitude shrublands.
Diet and feeding behavior
The diet of these black-headed jay species consists mainly of invertebrates and seeds. Invertebrates, small vertebrates like lizards, small birds, eggs and hatchlings are their primary food.These jays feed both on the ground and in trees.
