Imeri Warbling-Antbird Hypocnemis flavescens

Small antbird. Males are streaked black above, with a yellow-tinged throat and rusty flanks. Females are similar but with brownish streaks above. Inhabits the understory of both non-flooded and seasonally flooded forests, and regularly attends army-ant swarms. The song is a descending series of whistles that ends with a harsh note: “tew, tew-tzew-tzew-tur paw, paw.” The similar Guianan Warbling-Antbird has a white throat and is more streaked on the breast; the song also has a different pace. The Peruvian Warbling-Antbird has more black on the throat and breast and is less yellow below.
