Taxonomy and systematics The banded ground cuckoo is monotypic. It shares genus Neomorphus with three or four other species depending on the chosen taxonomic system. Description The banded ground cuckoo is about long, about half of which is its tail, and weighs about . Adults have a heavy decurved bill with a black to dusky maxilla and a grayish mandible tipped with blue-gray. Males and females have the same plumage. Adults have a black forehead and crown and a shaggy, glossy, blue-black, erectile crest. Their face is dark with bare blue skin behind the eye.

Distribution and habitat The banded ground cuckoo is found in the Chocó Ecoregion on the Pacific slope of southern Colombia and far northern Ecuador. It is "rare and localized, and occurs at very low density throughout its distribution." It inhabits wet to very wet tropical primary forest. In elevation it mostly ranges between though it has been observed both higher and lower. Behavior Movement The banded ground cuckoo is a year-round resident throughout its range. Locomotion The banded ground cuckoo is almost exclusively terrestrial, though it may fly into a tree to escape a predator or to roost. It mostly walks or runs on the forest floor and makes hops to catch prey. Feeding The banded ground cuckoo forages mostly by sprinting along the forest floor with abrupt stops to scan for and capture prey. It also hops onto low branches to pluck prey from vegetation. Its diet is mostly insects. It also includes significant amounts of other arthropods; small vertebrates like lizards, amphibians, and small birds; and sometimes fallen fruits. It often follows army ant swarms with other ant-following
