[edit] Behaviour

[edit] Diet

Mainly nectar, also insects, and figs growing from tree trunks. Forages mostly in the upper canopy of tall flowering trees, occasionally in vines and epiphytes, less frequenty in lower levels and scarcer in the lowest levels. Often forages on flowering sago (Metroxylon) by gleaning and probing. Not as active as congeners. Frequently in flocks of up to 20–30 birds in flowering trees and with other honeyeaters, including congeners such as Papuan Black Myzomela, Mountain Myzomela and Red Myzomela, also Red-flanked Lorikeet, infrequently alone or in pairs. Frequently joins mixed-species flocks.

[edit] Breeding

Nest with young observed in late March, breeding in east of range also believed to breed between late July and early August, later in west. Nest a scruffy, meagre cup made from strips of strong black arboreal lichen, suspended from fork of thin leafy branch, well hidden by foliage.

[edit] Vocalisation

High-pitched β€œchip” repeated occasionally. When displaying or defending territory gives a string of melodious chirps ending in hissing.

[edit] Movement

Resident, could be territorial, localised dispersal to utilise flowering trees.
