![]() It has been noted that they maintain special scratching posts, where they get rid of pollen and nectar sticking to their head. They tend to perch while foraging for nectar and do not hover as much as the syntopic Loten's sunbird. They pollinate the flowers of many plant species such as Bruguiera, Woodfordia, Hamelia and Sterculia. In one case the cuckoo was fed by an adult sunbird as well as an adult common tailorbird. Cases of nests being parasitised by the grey-bellied cuckoo are known. Helpers, females or possibly juveniles from the previous brood may sometimes assist the parents in feeding the young. The chicks fledge in about 17 days and continue to be fed by the male for a few days. The incubation period varies from 14 to 16 days. The eggs are incubated by both the male and female. The eggs are usually laid in the morning. When collecting cobwebs they are often seen at windows of homes, a time when they also sometimes end up tapping the window, possibly at their own reflection. Sometimes, eggs may be plain grey without markings as well. The clutch consists of two eggs which are generally oval, pale greenish and white with spots and streaks, becoming more dense at the broad end. The female stays in the nest at night a couple of day before laying the eggs. Nests may sometimes be built close to buildings or under open porches. The nest is placed on the end of branch and the entrance usually faces a bush. ![]() The nest is lined with soft fibres such as from the fuzz covering the seeds of Calotropis. The nest is constructed by the female alone although the male may fly alongside her. The nest is made up of fine plant fibres, cobwebs and is studded on the exterior with lichens, bark pieces, flying seeds and other materials. They breed through the year and may have two broods, but mainly during the monsoons. This species is found in a variety of habitats with trees, including scrub and cultivation and is usually absent from dense forest. It is found in Gujarat to the west (possibly a recent expansion ) and extending into Assam (Hailakandi ) or Meghalaya in the east. The purple-rumped sunbird is a common resident breeder in southern India, Sri Lanka and Bangladesh. Their call is ptsiee ptsit, ptsiee ptsswit or a sharp twittering tityou, titou, trrrtit, tityou. ![]() 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. The uppertail coverts are black and a weak supercilium may be visible. The female has a white throat followed by yellowish breast. 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 underparts are whitish with dark throat, maroon breast band and purple/violet patch in the throat which is visible in some angles. 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. Purple-rumped sunbirds are sexually dimorphic. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations for nectar feeding. Purple-rumped sunbirds are tiny, at less than 10 cm long. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart from females by their whitish throats. Males are contrastingly coloured but females are olive above and yellow to buff below. They build a hanging pouch nest made up of cobwebs, lichens and plant material. They can hover for short durations but usually perch to lap nectar from flowers. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. The purple-rumped sunbird ( Leptocoma zeylonica) is a sunbird endemic to the Indian Subcontinent.
