Diet and Foraging

Diet

Adult Scaled Antpittas are reported to prey predominantly on arthropods (Krabbe and Schulenberg 2003). Nestlings in southern Ecuador (Dobbs et al. 2001, 2003) were fed a variety of arthropods, including insects from several orders, and millipedes (Diplopoda). One large millipede (Polydesmida, Platyrhacidae, Nyssodesmus sp.: identified by H.F. Greeney from description given by authors) is apparently chemically defended by cyanide and benzaldehyde compounds (Heisler 1983). At these same nests in southern Ecuador, ca. 40% of adult provisioning visits included at least one earthworm. The diet of Scaled Antpitta perhaps also includes small vertebrates, such as small frogs.
