Herons (Ardeidae)
Yellow-crowned Night-heron (Nycticorax violaceus) - HBW 1, p. 419
French: Bihoreau violacé
German: Krabbenreiher
Spanish: Martinete Coronado
Taxonomy: Ardea violacea Linnaeus, 1758, Carolina.
Often placed in monospecific genus Nyctanassa, for instance on skeletal grounds; this separation from rest of night herons supported by work using DNA DNA hybridization.
