Distribution in the Americas

The range for this species extends across South America with two disjunct populations. C. s. sericocaudatus is restricted to the Atlantic Forest region of southeastern Brazil, northern Argentina, and northeastern Paraguay. Elevational range: 82 – 913 m. C. s. mengeli has been recorded within the confines of the Amazon Basin in southeastern Perú, northern Bolivia, to northern Brazil in the state of Pará. Elevational range: 227 – 1200 m.

Distribution outside the Americas

Endemic to the Americas.


C. s. sericocaudatus inhabits forest or forest edges of second growth or subtropical evergreen forest (Cleere 1998, Cole 2003).

C. s. mengeli inhabits mature, hilly tropical forest (Schulenberg and Remsen 1982), scrub border of old fields in cutover tropical rainforest (Hardy 1985), gallery forest (Parker and Bailey 1991), terra firme forest (Alexio et. al. 2000), and undisturbed lowland floodplain and evergreen tropical rainforest. The residential population at CCBS prefers pockets of older forest away from areas of that are prone to flooding (streams, small swamps) (Wilkinson 2009).
