Habitat and Ecology [top]

Habitat and Ecology:The vegetation at the type locality (Panga) includes several Cerrado physiognomies, including “Veredas” (a vegetation dominated by grass-like plants, with dispersed bushes and Mauritia flexuosa palms) and a riverine forest running along the Panga River (2 m wide). Human altered areas are covered by the exotic grass Brachiaria sp.. The local weather presents a hot and wet summer (Sep.–Mar.), and a cold and dry winter (Apr.–Aug), when frosts may occur. Males were heard calling on the ground or perched (up to 60 cm height) amidst dense tufts of natural grass-like herbs in Veredas or on Brachiaria sp. Up to 200 m from permanently wet soil. Rarely, when fires cleared open areas from
grasses, males were heard also from within forests or forest borders. Calling activity was observed between October and March, being most intense in the afternoon and first hours of the night (Giaretta et al., 2007).
