Purple-rumped sunbird : ウィキペディア英語版 | Purple-rumped sunbird
The purple-rumped sunbird (''Leptocoma zeylonica'') is a sunbird endemic to the Indian Subcontinent. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. They can hover for short durations but usually perch to suck nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are brightly coloured but females are olive above and yellow to buff below. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart by their whitish throats. ==Description==
Purple-rumped sunbirds are tiny at less than 10 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations for nectar feeding. Purple-rumped sunbirds are sexually dimorphic. The males have a dark maroon upperside with a blue-green crown that glistens at some angles, bright green shoulder patch and violet/purple rump patch which is generally hidden under the wings. The underparts are whitish with dark throat, maroon breast band and purple/violet patch in the throat which is visible in some angles. The iris is generally reddish in color. In the Western Ghats, it can overlap in some areas with the crimson-backed sunbird but the male of that species has reddish upperparts, a broader breast band and generally darker eyes. The female has a white throat followed by yellowish breast. The upperside is olive or brownish. The uppertail coverts are black and a weak supercilium may be visible. The nominate subspecies from Sri Lanka has a more bluish violet throat whereas the Indian form ''flaviventris'' (two other proposed populations ''whistleri'' from Maddur in Karnataka and ''sola'' from Pondicherry are subsumed) has a more pinkish tinge. Their call is ''ptsiee ptsit, ptsiee ptsswit'' or a sharp twittering ''tityou, titou, trrrtit, tityou...''.
