Restinga Antwren Formicivora littoralis

  • Order: Passeriformes
  • Family: Thamnophilidae
  • Monotypic
  • Authors: Flávia G. Chaves, Maurício B. Vecchi, Tonny Marques de Oliveira Jr., Yara Ballarini, and Maria Alice S. Alves



The primary foraging tactic performed by male and female Restinga Antwrens is "simple perch-gleaning" (Chaves 2010), following the terminology of Fitzpatrick (1980).


Little information. Restinga Antwrens exhibit site fidelity, and individuals defend small territories (less than 0.5 ha) throughout the year (Chaves, 2014).

Sexual Behavior

Socially monogamous (Chaves 2014).

Social and interspecific behavior

Restinga Antwrens usually are solitary or in pairs.


The main sources of predation on Restinga Antwren are unknown. We observed a Guira Cuckoo (Guira guira) predating nestlings and Oliveira (2007) registered a snake species (Pseustes sulphureus) also predating nestlings. Many fragments of restinga where the antwren occurs have been invaded by marmosets (Callitrix spp.), which are potential predators of eggs and nestlings of Restinga Antwren.
