French: Ibijau gris
German: Urutau-Tagschläfer
Spanish: Nictibio Urutaú
Other common names: Grey/Lesser Potoo

Costa Rican birds, originally all included in single race, costaricensis, now thought to include two species; because costaricensis is currently recognized as a race of N. jamaicensis, birds of present species in Costa Rica and elsewhere in N are referred to adjacent race panamensis, although they possibly represent an unnamed taxon. Invalid race cornutus, recognized by some earlier authors, is now considered synonymous with nominate.. View all taxonomy...

Two subspecies currently accepted.
