Named After Its Sweet Sound, The Crimson Sunbird Is A Precious Emerald That Shines Gorgeously

In most of the range, the males have a long green-blue tail, but subspecies Aethopyga siparaja nicobarica from the South Nicobar Island (Great and Little Nicobars, Kondal and Meroe Islands) lack the long central tail feathers. The adult female has an olive-green back, yellowish chest and white tips to the outer tail feathers.
