About These Birds
Bicol Ground-warbler
The Bicol Ground-warbler is a near-threatened, terrestrial warbler endemic to the Bicol Peninsula of Luzon, Philippines. It has plain brown plumage and forages on the forest floor for insects and other invertebrates. Its restricted range and dependence on lowland forest make it vulnerable to deforestation.
