Sulawesi Babbler

The Sulawesi babbler is a small, stocky, long-legged ground babbler with plain brown upperparts and paler underparts that vary from whitish to deep yellow among populations. It is usually seen alone or in pairs close to the ground. Its restricted range and combination of long legs, plain appearance and terrestrial habits separate it from other local understorey birds. Calls include a musical phrase and repeated loud keer notes (eBird/Merlin account).

It inhabits dense undergrowth, thickets and forest edge from the lowlands to about 1,900 m, and also uses degraded former forest, gardens and plantations. Birds forage on the ground for invertebrates. Ecological datasets report a two-egg clutch. Genetic, acoustic and morphological research finds rapid divergence among populations on Sulawesi and land-bridge islands, consistent with limited dispersal by an understorey specialist; ITIS recognises four subspecies (Oiseaux.net; BirdLife DataZone; published evolutionary study; ITIS).
