Physical description Click here for a physical description Olive-backed Sunbirds are very small nectar-eating birds. Their plumage is dimorphic, i.e. males and females are different. Male Olive-backed Sunbirds have, as their most prominent feature, a metallic-blue "bib" (or "gorget") down their throat and the width of their breast. The belly, flanks, vent and undertail coverts are bright-yellow. The frons, crown and back are all citrine-olive. The flight feathers have dark-grey leading edges, while the uppertail is dark-grey. They have narrow bright-yellow eyebrows. Female Olive-backed Sunbirds do not have the metallic-blue "gorget". Their entire front, from throat to undertail coverts, is bright-yellow. The eyes of both sexes have dark-brown irises. The long, slightly down-curved bill is dark-grey. The legs and feet are grey. Juvenile Olive-backed Sunbirds resemble females.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Olive-backed Sunbird is available HERE . Olive-backed Sunbirds are found throughout the tropics of south-eastern Asia, from Myanmar, southern China and Vietnam, via Malaysia, the Philippines, Indonesia and Timor Leste to the Solomon Islands and, via the islands along Torres Strait to tropical near-coastal north-eastern Australia. Olive-backed Sunbirds, race "frenata", are found only along the North-East coast of Australia, from the tropic of Capricorn at Yeppoon, QLD, to the tip of Cape York peninsula and also on the western coastline of the peninsula, as far South as about Kowanyama, QLD. Olive-backed Sunbirds are usually found in mangroves and around the edges of rainforest. They adapt very well to the presence of humans and are also found in urban parks and gardens.

Food, Diet

To the best of our knowledge Olive-backed Sunbirds feed exclusively on nectar. They profit from the creation of urban gardens and parks with flowering plants.
