ハイイロパプアヒタキ Melanodryas cryptoleuca

A fairly small bird of montane forest. Slaty-gray plumage, paler below with blackish wings and tail. Perches low down, often on diagonal branches or vertical mossy trunks, flicking its tail and scanning the ground for insects. Very similar to Blue-gray Robin, but Smoky lacks the bluish tinge to the gray, has a paler belly and less contrasting black wing feathers. Voice, an up-and-down “whit-tyap!” repeated in series.
