89. Notes on the vocalizations of Bar-winged Cinclodes (Cinclodes fuscus)

Song is a rattling trill at more or less same pitch or slightly rising at end (Fig. 1). There is some variation among the races: oreobates: no recordings found heterurus: trill consists of clear short overslurred notes, at start gradually increasing in pitch and amplitude, at end rising in pitch and becoming more spaced and notes downslurred albidiventris (few recordings of song): trill consists of short notes which have pronounced harmonics, thus sounding more metallic rattling compared to previous race. There is no clear starting and ending part, rattle is quite uniform over its entire length.
