Vigors's sunbird  Vigors's sunbird ("Aethopyga vigorsii"), Sahyadri sunbird, or western crimson sunbird, is a species of sunbird which is endemic to the Western Ghats of India. It has been considered as a subspecies of the crimson sunbird ("Aethopyga siparaja") but it does not have the central tail as elongated and is restricted in its distribution. The male has yellow on the lower back and tail is bottle green. The species is distributed mainly in the northern Western Ghats but has been reported from the Nilgiris. It was named after Irish-born zoologist Nicholas Aylward Vigors by Colonel William Henry Sykes.
