What is "sapayoa"

The sapayoa or broad-billed sapayoa (Sapayoa aenigma) is a suboscine passerine found in lowland rainforests in Panama and northwest South America. As the epithet aenigma ("the enigma") implies, its relationships have long been elusive. It is easy to overlook, but appears to be common in a wide range and is not considered threatened by the IUCN.
