The genus Calornis comprises some birds which are frequently termed Glossy Starlings or Tree-Stares. They are largely represented in South-eastern Asia and range to Australia. I do not know how far the Glossy Starlings of Africa are related to the Glossy Starlings of Asia, but there seem to be important differences between some of them.
In Calornis the plumage is highly glossy; the bill is stout with the culmen curved; the nostrils small and round ; the wing sharp and long ; the tail moderate in Length and considerably graduated, and the foot strong.
Only one species of Calornis occurs in India, and of this species the insular race from the islands of the Bay of Bengal is subject to some variation in colour.
