Restinga Antwren is a resident on the coast of southeastern Brazil, where it occurs only in a vegetation type called restinga (sandy plain coastal vegetation), an ecosystem associated with the Atlantic Rainforest. Its distribution is entirely restricted to Rio de Janeiro State, specifically in seven municipalities – Saquarema, Araruama, Arraial do Cabo, Iguaba Grande, São Pedro da Aldeia, Cabo Frio e Armação dos Búzios and associated islands – Cabo Frio and Comprida (Gonzaga and Pacheco 1990, Vecchi and Alves 2008, Mattos et al. 2009).
Distribution outside the Americas
Endemic to the state of Rio de Janeiro, Brazil, South America.
Restinga is a sandy plain coastal vegetation covered by a mosaic of plant communities, which has various physiological responses to a drier habitat (Duarte et al. 2005). The vegetation, in general, is characterized by dense, scrubby thickets that form an impenetrable canopy that prevents light penetration (Araújo et al. 2009). Cacti and bromeliads are present in abundance (Gonzaga and Pacheco 1990).
