Former species

and large white wing patches which are obvious in flight. The bill and strong legs are bright yellow or orange, and there are yellow wattles on the head, the shape and position of which vary with species. The sexes are similar, but juveniles have a duller bill.


Vocalisations

Hill mynas are renowned for their ability to mimic the human voice. It has been claimed that the hill mynah is the best
talking bird Talking birds are birds that can mimic the speech of humans. There is debate within the scientific community over whether some talking parrots also have some cognitive understanding of the language. Birds have varying degrees of talking ability: ...
and the best mimic in the world.


Distribution and habitat

This genus has representatives in tropical southern Asia from India, Bangladesh and Sri Lanka east to Indonesia, and the common hill myna, a popular cage bird, has been introduced to the United States.


Behaviour and ecology


Breeding

The hill mynas are resident breeders typically found in forest and cultivation. The nest is built in a hole and the usual clutch is two or three eggs.


Food and feeding

Like most starlings, the hill mynas are fairly
omnivorous An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize ...
