| Neotropical River Warbler Phaeothlypis rivularis (aka Riverbank Warbler; Basileuterus rivularis) Brazilian name: pula-pula-ribeirinho |
||||
 |
Brazil The Neotropical River Warbler is found along rivers and streams in forests where it forages on or close to the ground hopping rather than walking. |
|||
 |
It has 3 disjunct ranges: in south east Brazil; in Bolivia; and from south Venezuela to the state of Maranhão in north-east Brazil. It is brownish-olive above with a grey crown, buff supercilium and lower cheek either side of a dark stripe through the eye. Underparts are whitish with buffy flanks |

 |
Sick mentions the relatively low frequency voice of the Neotropical River Warbler compared to other wood-warblers who inhabit the forest canopy. These lower frequencies allow their voices to better penetrate the dense vegetation and compete with the noise of running water. There are some recordings on xeno-canto. |
