Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Lowland and hill forest, coconut plantations, mangroves, nypa forest, even visiting trees in villages; usually in understorey. On Kai Is ranges to 250 m.

Movement

No information.

Diet and Foraging

Presumably fungus and lichen taken by bark-gleaning on trunks of flowering trees, particularly figs; most stomach contents are an indeterminate paste, but small seeds found.

Sounds and Vocal Behavior

Calls include high-pitched short notes such as “tsit” or “tsee”. Also short phrases of 2–4 different notes, e.g. “tsee-see-seet”.

Breeding

Sept–Mar on basis of nestling in Oct, breeding condition male in Nov, nest with young in Mar. Nest in hollow excavated in arboreal termitarium 3–4 m from ground. In one nest there were 6 adults as well as 2 nestlings, since the nest was also used for roosting by young from previous broods.
Not globally threatened. CITES II. Very common on Kai Is, scarce on Aru Is (apparently naturally), moderately common throughout W Papuan Is.
