The Yellow-crowned Night Heron (Nyctanassa violacea) haunts coastal marshes from Massachusetts to Brazil, and Panamá to Perú on the Pacific side. It also occurs on the Galápagos and throughout the West Indies. Unlike its nearly cosmopolitan cousin the Black-crowned Night Heron (Nycticorax nycticorax), which hunts fish from dawn to dusk, the Yellow-crowned often stalks the crustaceans that make up the bulk of its diet at midday. In recent years this species has increased its range in the United States as far west as Illinois. The butterfly on the bank belongs to the Central American genus Eunica.
