Yellow-crowned night heron
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. source
