Buff-rumped Warbler Myiothlypis fulvicauda


Sounds and Vocal Behavior


Song described as a short warble which is followed by a set of 8-9 “chew” notes. The call has been described as a “tschick” (Curson 1994). Ridgely describes the song as “vigorous song an accelerating crescendo of loud “tew” notes that end with a series of emphasized fast “tchéw” notes” (Ridgely & Greenfield 2001a) Most authors describe the song as a fast set of “tschick” notes followed by “chew”.

Unlike many species, the female also sings a song. Described by Skutch as “a low, sweet warbling like the opening part of the male’s song, but more elaborate and longer continued ” (Skutch 1954). He notes that the female sings far less frequently than the male in most seasons, with female song most commonly observed in Costa Rica in October and November, possibly associated with pair formation.

A recent study showed that Buff-rumped Warblers vary their song frequency and amplitude in relation to environmental noise (birds found along noisier streams sing louder, higher-pitched songs), and that the first part of the song may contain information about the singer (Escalante 2013).
Additional recordings of the songs can be found in Macaulay Library and on Xeno-Canto.
