Nyctanassa is a genus of night herons from the Americas, especially (but not exclusively) warmer coastal regions. They were formerly included in the genus Nycticorax , but today all major authorities recognize them as distinct.
The genus Nyctanassa was introduced in 1887 by the Norwegian born zoologist Leonhard Stejneger to accommodate a single species, the yellow-crowned night heron, which is therefore the type species. [1] [2] The genus name combines the Ancient Greek nux meaning "night" with anassa meaning "queen" or "lady". [3]
The genus contains the following two species, of which only one is still extant: [4]
