Mosquitero Cejiblanco Abroscopus superciliaris

Small and modestly bright warbler of lowland to submontane forests, usually seen moving around quickly in the undergrowth. Not especially eye-catching, but combination of olive-green upper parts, bright yellow belly, and white eyebrow and throat are unique within its range. Usually seen in small flocks, often with other species. Song is a short, pretty phrase of tinkling high whistles, the highest note often at the end.
