Comportement

The rufous-tailed palm thrush is shy, usually found in pairs or small groups. It gives the call churr when alarmed. Its song, usually given at dawn or dusk, is a series of loud and melodious whistles, mixed with babbling and chattering. Pairs of birds sometimes duet. It forages on the ground, mainly feeding on adults and larvae of beetles, spiders, and fruits. Breeding has been recorded from August to April. The species is monogamous. The nest is built at the base of a palm leaf, in a crevice in a tree trunk, and sometimes in other positions. It is a deep, thick cup, made of mud and lined with grass and plant fibres. There are one to four eggs in a clutch. The eggs are pale greenish, with faint freckles. It is not migratory.
