[edit] Habitat

Forest and closed woodland.

[edit] Behaviour

Seen in pairs or family groups. Does not flock with other weavers, but does join multi-species flocks foraging for insects.

[edit] Diet

Probes leaves and bark for arthropods; also eats fruit, nectar and flowers.

[edit] Breeding

Monogamous and territorial. The nest is woven using vines and creepers, and has a long entrance tube; probably built mainly by the male. Two to four eggs are laid, and incubated for about 16 days. The young are fed by both parents, and remain in the nest for about 22 days. Snakes are known to raid nests.
