Taxonomists have not reached agreement on the curve-billed scythebill. The International Ornithological Committee (IOC), BirdLife International's Handbook of the Birds of the World (HBW), and the Clements taxonomy assign it these three subspecies:

Until 2023 the IOC and Clements also included them. In July the IOC split off probatus and carsosoi to create the Tapajos scythebill and multostriatus to create the Xingu scythebill. Clements followed suit in October 2023. HBW had previously made those splits.

Subspecies C. p. gyldenstolpei was originally proposed as a full species. This article follows the three-subspecies model. The curve... Wikipedia →
