slaty-backed thrush Geokichla schistacea

An unmistakable black, white, and gray thrush. Gray upperparts and black head marked with bold white cheek patch and long white eyebrow. Throat and chest black and belly clean white, peppered with black spots on the upper part. Occurs in forest, where it forages on the ground but often perches in trees just below the canopy, particularly when singing. Confined to the Tanimbar Islands. Complex song is a sequence of melodious whistled stanzas, mostly upslurred at the start, and interspersed with quick “chew-chew-chew” phrases.
