キバラムシクイタイランチョウ Pseudocolopteryx flaviventris

Small two-toned flycatcher, olive-brown above and yellow below. Note the rufescent crown patch. Found in tall-grass marshes, especially those with sedges. Typically difficult to locate, but during migration can be found in various areas with tall grass. The call is a series of nasal squeaky notes: “chek, chek, chek, chek-chick-chick-chiquetik.” The rather similar Dinelli's Doradito has a more olive-colored, less brownish back.
