Cyphorhinus modulator (d’Orbigny, 1838)


Cyphorhinus modulator (d’Orbigny, 1838) 

English name: Ferruginous Wren

Portuguese name: Uirapuru-ferrugíneo

Type-locality: Yuracares, Bolivia.

Diagnosis: overall more reddish rather than brownish coloration, especially on the ear coverts, sides of the neck, chin, throat and chest. The belly is yellowish brown (M 10YR 5/6, 5/8) and thus contrasts with the chest. Flanks are slightly darker than the belly (cinnamon brown, S 7YR 4/4). Larger than C. transfluvialis  .

Voice: a variable set of complex phrases, each with a high number of notes (7–17), long duration (2–6 s) and slow pace (2.5–3.5 note/s). Each phrase is repeated several times before changing to the next.

Distribution: from the lowlands of eastern Peru, to the south of the Río Marañon east to the Rio Madeira in western Brazil and as far south as northwestern Bolivia ( Figure 4View FIGURE 4)
