About These Birds
Baikal Grasshopper-warbler
The Baikal Grasshopper-warbler is a small warbler that breeds in northeastern Asia and winters in South and Southeast Asia, weighing about 10.3g with a wingspan of 10.6cm. It inhabits tall grass and reed beds, where it sings a distinctive reeling song. Like other Locustella warblers it is secretive and more often heard than seen.
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.
