Abstract

We studied the Red-billed Currasow (Crax blumenbachii) in Vale Natural Reserve, Linhares, Espírito Santo State, Brazil, using camera traps. We found the Red-billed Curassow present in the entire area of the reserve (∼ 22,000 ha) during 40 months of camera trapping (2005–2008). Most records were of single individuals, especially males, but pairs and even groups of individuals were also recorded. Males were paired with one and two females, suggesting polygyny in the species. The species was recorded throughout the day with one peak from 0500 to 0600 hrs and another after 1600 hrs. The daily activity pattern was similar for males and females. The number and widespread nature of the records suggests the local population of this species may be higher than previously thought.
