Diet and Foraging

Diet

Diet

Arthropods constitute the bulk of the diet, with ants (Formicidae), grasshoppers and crickets (Orthoptera), maggots (Diptera larvae), beetles (Coleoptera), spiders (Araneae), and land snails (Gastropoda) especially well represented (Van Tyne 1935, Mestre et al. 2010), although the species also consumes small vertebrates such as frogs, lizards, and snakes (Skutch 1945, Poulin et al. 2001, Lopes et al. 2005).

Food Selection and Storage

In portions of its geographic range where Black-faced Antthrush is sensitive to habitat fragmentation and loss, such as Amazonian Brazil, this species forages more selectively than its congener Rufous-capped Antthrush (Formicarius colma), and takes larger prey on average (Mestre et al. 2010). Black-faced Antthrush does not store food.
