Morphology

The ''Acridotheres'' mynas are generally dark or dull birds with and fluted calls like most starlings; the sexes are similar. They walk and hop, and may share adaptations along with the ''Sturnus'' starlings that have modifications to the skull and its muscles for open bill probing or prying. They resemble the hill mynas (''

'') with which they often co-occur, in having large white or buff wing patches which are obvious in flight and in some also naked areas on the head, but differ in that only the head plumage is glossy, and the underparts tend to be paler. The naked head patches are different in arrangement. ''Acridotheres'' mynas are also much more terrestrial than ''Gracula''. Several species have frontal crests which become covered with pollen when the birds take nectar from flowers, and may play a role in pollination.

Behaviour

They have bowing courtship displays, whereas ''Gracula'' has no visual display. They lay unmarked pale blue eggs. Like most starlings, the ''Acridotheres'' mynas are fairly
