The white-eared puffbird feeds on arthropods, and small vertebrates, such as lizards, amphibians (including poisonous frogs) and even small marsupials, commonly taken from the ground. Its diet appears to be opportunistic. Invertebrate prey includes social wasps (Vespidae), beetles, homopterans, lepidopterans and other large insects caught in mid-air, often along streams, but also non-volant animals such as insect larvae, millipedes, centipedes, scorpions, and even velvet worms and crabs. Subspecies Two subspecies are recognized: Nystalus chacuru uncirostris - found in eastern Peru, northeastern Bolivia and adjacent Brazil. Nystalus chacuru chacuru - found in northeastern, eastern and southern Brazil, eastern Paraguay and northeastern Argentina (Misiones).
