Although Fjeldså and Krabbe (1990) suggested tadpoles and frogs as food, this has not been confirmed. Known food items recorded include large beetles, grubs, slugs, giant earthworms (Rhynodrylus), and other large earthworms (Krabbe et al. 1994). Giant earthworms are quickly cut into pieces ca 8 cm long and gulped down (Krabbe and Schulenberg 2003). Several localities regularly have Giant Antpittas that arrive to be fed by humans at worm-feeding stations (Woods et al. 2011), and it seems likely that these are an important part of their natural diet, as has been suggested for other large antpittas (Greeney et al. 2008a, Greeney 2012).
