The BLUE-EARED GLOSSY STARLING comes in two species, the LESSER, Lamprotornis chloropterus, in the first two photos above, and the GREATER, Lamprotornis chalybaeus,
above right. Both have a range of most of sub-Saharan Africa and both look similar in size and plumage. The extent of blue plumage on the under-belly is the determining feature between the two species.
The GREY STARLING, also called the WHITE-CHEEKED STARLING, Sturnus cineraceus, comes from eastern Asia. Male and female have similar plumage.

The GROSBEAK STARLING, Scissirostrum dubium, as its name suggests, has a disproportionately large beak.
Also called the Grosbeak Mynah and FINCH-BILLED MYNAH and, after its scientific name, the SCISSOR-BILLED STARLING, it comes from Sulawesi,
Indonesia. It also has a distinctive orange flame-like flecking on its rump. Male and female have similar plumage.
The ASIAN PIED STARLING, Sturnus contra, also called the PIED MYNA, comes from India,
Indonesia and part of southeast China. (May be moved from "Sturnus" genus to older name "Gracupica.")
Male and female have similar pied plumage and orange eye-rings and base of bill;
different subspecies have yellower or redder orange hues and more/less extensive eye-rings/white cheeks.
The DAURIAN STARLING, Sturnus sturninus, also called the PURPLE-BACKED STARLING in view of its brownish-purple
(purplish-brown?) back, comes mainly from Mongolia, Indochina and China.
The male has more purple in the brown of his back. The female has slightly lighter-coloured plumage.
The BLACK-COLLARED STARLING, Sturnus nigricollis, is native to south China and Indochina.
Male and female have similar black and white plumage and yellow, bald eye-rings.
