 in the Nectariniidae family found in the moist forests of South and Southeast Asia. Unlike typical sunbirds, males and females are very similar in plumage. They are usually seen in ones or twos and frequently make a tzeck call and are most often found near flowering plants where they obtain nectar.

Description

The distinctive long beak set it apart from other sunbirds. The sexes are alike except for a paler base to lower mandible in the female. Male has all black beak. They are found close to their favourite nectar bearing trees, often species of wild Musaceae or flowers in gardens. They have a buzzy zick-zick call that is made regularly when disturbed or when foraging. The song is series of rapid chipping notes and these can go on for long periods.

s. It is usually found below the canopy. They are also found in gardens, attracted especially by flowers that yield nectar.

Behaviour and ecology

They have been noted as good pollinators of wild banana species and several species of the ginger family and often visit Loranthus sp. (= Dendrophthoe sp.), Indian silk cotton tree and Indian coral tree for nectar. They are often seen in plantations in forest areas. Although they are more often seen in secondary forests or in clearings and appear to be tolerant of human activities, they have become extinct in some forest fragments. In Singapore they have gone locally extinct within the botanical garden.

The breeding season in northeastern India is March to September but mainly May to August. In southern India it breeds from December to August. Two eggs are the usual clutch. The nest is a compact cup attached under a leaf of banana or similar broad leaved plant. The nest is suspended from the underside of the leaf using 150 or so "pop-rivets" of cobwebs and vegetable fibre, a unique method of using spider silk for animal architecture.
