About These Birds

Biak Leaf-warbler

The Biak Leaf-warbler is a near-threatened, small warbler endemic to Biak Island in western New Guinea. It has greenish-olive upperparts and yellowish underparts typical of leaf-warblers in its genus. It forages actively in the forest canopy for insects, gleaning them from leaves, and its small island range makes it inherently vulnerable.
