Rotkappen-Dickichtschlüpfer Synallaxis ruficapilla

Medium-sized, long-tailed spinetail found in the understory of humid forests often accompanying mixed-species flocks. Note the yellowish eyebrow, contrasting with dark cheeks, a pale throat, and a richly rufous crown, wings, and tail. It is brownish on the back and buffy gray below. The song is very distinctive nasal series of “prrr” rattles followed by a squeaky “Dje,” such as “prrrDje-prrrDje.”
