Potoos (Nyctibiidae)

Great Potoo (Nyctibius grandis) - HBW 5, p. 299

French: Grand Ibijau German: Riesentagschläfer Spanish: Nictibio Grande
Other common names: Grand Potoo

Taxonomy: Caprimulgus grandis J. F. Gmelin, 1789, Cayenne.
Currently accepted races are doubtfully valid, and perhaps represent merely extremes in broad geographical size trends and individual plumage variation. No taxonomically recognized variation in most of extensive range, despite great genetic divergence on opposite sides of Andes and possible population disjunction between Amazonia and Atlantic forest; may contain undescribed “cryptic” taxa. Two subspecies tentatively accepted.

Subspecies and Distribution:

  • guatemalensis Land & Schultz, 1963 - extreme S Mexico, Guatemala, and possibly Honduras.
  • grandis (J. F. Gmelin, 1789) - Nicaragua to N South America, where mostly E of Andes throughout Amazonia to N Paraguay, and in SE Brazil; may occur locally between Amazonia and Atlantic forest regions.
