Wikipedia Abstract

The yellow-crowned night heron (Nyctanassa violacea, formerly in the genus Nycticorax), is one of two species of night herons found in the Americas, the other one being the black-crowned night heron. It is known as the Bihoreau Violacé in French and the Pedrete Corona Clara in Spanish. A related heron, the Bermuda night heron, was endemic to Bermuda, but became extinct following human colonisation.
