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.

Alström's Warbler

Alström's Warbler is a tiny leaf warbler weighing just 8 g with a short 11.1 cm wingspan, found in dense forest undergrowth. It gleans insects from foliage with quick, restless movements typical of its family Phylloscopidae.
