hello every one, its another week of hard work and we at gifted by nature display we wish all the best to those going hard and harder and never give up. in this week we shall look at olive-backed Sunbird. the olive-backed Sunbird (cinnyris jugalaris), also known as yellow bellied sun birds, is a species of Sunbird from southern Aisa to Australia. the sun birds are a group of very small old word passerine birds which feed largely on nector, although they will also take insects. most species can take nector by hovering, but usually perch to feed most of the time.
the olive-backed Sunbird is common across southern china to the Philippines and Malaysia down to north of Australia. they are small songbirds,at most 12cm long in most subspecies. the underparts of both made and female are bright yellow, the backs are a dull brown color.
the forehead, throat and upper breast of the adult male is a dark, metallic blue-black. in the Philippines the males of same subspecies have an orange band on the chest. in wallalea and northern new guinea some subspecies have most of the underparts blackish, and in southern china and adjacent part of Vietnam most of the under parts of the male are greyish-white.
originally from mangrove habitat, the olive-backed sun birds has adapted well to human, and is now common even in fairly dense populated areas, even forming their nests in human dwellings.
the birds mate between the august and January in the southern nest which is flask-shaped, with an over hanging porch at the entrance, and a trail of hanging material at the bottom end.
after building the nest, the birds abandons the nest for about a week before the female returns to lay once or two greenish-blue eggs. the eggs take a further week to hatch. the female may leave the nest for short periods during the day during incubation. after the chicks have hatched, both male and female assist in the care of the young, which leave the nest about two or three weeks.
