There are a few hybrids which circulate in the private trade, but I’m not sure of which species. The other myna and starling species kept in this aviary are:
Black-collared mynah (G. nigricollis)
Yellow-faced mynah (M. dumontii)
Metallic starling (A. metallica)
Common mynahs aren’t kept, just this hybrid is. I do have a full species list of the aviary I intend to post eventually, there are over 500 specimens of 85 species.
