Interestingly, the apricot-colored feathers displayed by the male Olive-backed Sunbird are only visible when it needs to use them for display purposes. The rest of the time, they remain hidden under their wings. The female of the species is equally attractive, with a bright yellow and brown back. However, it lacks the more colorful plumage of the male.

The Olive-backed Sunbird can be found in Southeast Asia and Australia, from southern China to Indonesia and northeastern Australia. It was originally found in mangrove swamps, but has adapted to human-inhabited areas and can now be found in forests, orchards, coconut plantations, towns and villages.

As an omnivorous bird, the Olive-backed Sunbird has a varied diet consisting of nectar and invertebrates. It obtains nectar from flowering plants such as coconut and papaya and likes to hunt spiders, ants and caterpillars.

The breeding season for the Olive-backed Sunbird is from December to July. During this time, the female builds a pear-shaped nest with a small side entrance, using grass stems and other fibrous materials. She lays 1 to 3 pale green eggs with brown spots and incubates them for 11 days until they hatch. The chicks are then fed by both parents until they fledge after 15 to 16 days.

Despite the threats many bird species face due to changes in habitat and other factors, the population of Olive-backed Sunbirds is expected to be stable. This is good news for both bird lovers and nature lovers, who can continue to enjoy watching this beautiful bird in its natural habitat.
