Fire-tailed Sunbird

The fire-tailed sunbird is a sunbird of temperate forests and subtropical or tropical moist montane forests across the northern Indian subcontinent, primarily in the Himalayas, in Bangladesh, Bhutan, India, Myanmar, Nepal, Thailand and Tibet. Breeding males have a scarlet nape and mantle, a yellow-orange breast, an olive-green belly and a long scarlet tail, reaching about 15 cm including the tail; females are about two-thirds that length.

Females have a grey-olive head and throat and a yellow belly, and are told from the similar female green-tailed sunbird by a straighter bill and squarer tail. It eats insects and nectar, breeds in rhododendron shrub, and both parents feed the young. (Wikipedia, general species account)
