Oruguero de la Sonda Coracina larvata

Chunky, dark gray bird with a dark face. Dark face patch is more extensive on males than females; males on Sumatra have entirely black heads. Inhabits moist foothill and montane forest. Moves through the upper levels of forest, often with other species in mixed flocks. Gives various high squeaky calls, including an inflected “weee-tee!”.
