Kahverengi Vireo Vireo leucophrys

Rather plain vireo of humid evergreen and pine-evergreen forest in highlands and foothills. Northern populations (Mexico to Nicaragua) look and sound much like Warbling Vireo, but with browner upperparts and a distinctly brown cap. Usually at middle to upper levels in trees, where sings persistently in summer. Southern populations (Costa Rica to South America) have different song and distinct yellowish wash on breast and belly.
