Also frequents stand-alone groups of trees in cleared areas, teak and rain tree plantations. Needs arboreal termitaria to breed. Usually below 500 m, but has been recorded up to 1300 m in the northeast (Mt Bosavi). | Usually in the lower canopy of monsoon and riverine forest, additionally in primary rainforest, floodplain forest, parkland, secondary growth forest, dense coastal palm scrub, mangroves and gardens.

Distribution

Taxonomy
This is a monotypic[1] species.
Habitat
Usually in the lower canopy of monsoon and riverine forest, additionally in primary rainforest, floodplain forest, parkland, secondary growth forest, dense coastal palm scrub, mangroves and gardens. Also frequents stand-alone groups of trees in cleared areas, teak and rain tree plantations. Needs arboreal termitaria to breed. Usually below 500 m, but has been recorded up to 1300 m in the northeast (Mt Bosavi).
Behaviour
Diet
Arthropods, including grasshoppers and locusts, stick-insects, beetles, larvae, earthworms and large spiders, crabs, small vertebrates, including frogs, lizards, birds and small mammals. Forages mainly in lower canopy by gleaning sometimes seen on the ground, where it occasionally digs. Attacks birds caught in mist-nets, gets mobbed by small birds, suggesting that it might predate nestling or eggs.
Breeding
Mainly breeds in the late dry and early wet seasons, nest excavation has been reported in mid-August and September, additionally in May–June. Eggs nhave been reported in early October and nestlings seen October, December, January and early February. Both adults dig a tunnel with nesting chamber in an active termite nest, between 2–40 m up on side of tree.

Vocalisation
Common calls include a loud, repetitive “tok” or “chok”, a very fast “tok-tok-tok” sounding like “trrrk”, repeated every 2 seconds, a series of loud hoarse barks or laughs at the same pitch, these calls often encourage birds in adjacent territories to respond, several birds calling together can sound like chorus of Blue-winged Kookaburra.
