Range DescriptionThis taxon exists in two forms: the nominate undulata occurs in two disjunct areas, one in Colombia, and the other from Venezuela through Guyana, Suriname and French Guiana to extreme north-east Brazil; the race gigantea is found in eastern Bolivia, eastern Paraguay and south-east Brazil, and probably also in Uruguay and north-east Argentina (del Hoyo et al. 1996). It occurs in Reserva Natural del Bosque Mbaracay and Golondrina Private Nature Reserve, Paraguay (Lowen et al. 1996), and all recent records for Venezuela have been from Canaima National Park and World Heritage Site (C. Sharpe in litt. 2003).
