Jungle Myna

The jungle myna is a starling, 23cm long, patchily distributed across much of the mainland Indian subcontinent but absent from the arid zones of India, and a common resident breeder in tropical southern Asia from Nepal, Bangladesh and India. It has grey plumage, darker on the head and wings, a tuft of feathers on the forehead forming a frontal crest, pale yellow or blue eyes depending on the population, and an orange-yellow bill with a dark base (Wikipedia, general species account).

Sexes are indistinguishable. The calls are higher pitched than the common myna's, and foraging flocks make clipped cheeping contact calls. Both sexes take part in nest building, incubation and feeding, and the usual clutch is four to six turquoise-blue eggs. The species has spread on its own to some Pacific islands. The source read does not name Bhutan.
