The Red-billed Scythebill is a forest bird with a very long, down-curved bill and fine streaks on the face and breast.
It measures about 22–28 cm. The very long, down-curved bill, finely streaked face and breast, brownish-red back and tail, and paler belly are characteristic.
It inhabits a range of lowland and hill forests and feeds mostly on arthropods and spiders, with some vertebrates also recorded. It forages alone or in pairs, and both adults incubate the two to three eggs.
