The yellow-crowned night heron (Nyctanassa violacea), is one of two species of night heron. Unlike the black-crowned night heron, which has a worldwide distribution, the yellow-crowned is restricted to the Americas. It is known as the bihoreau violacé in French and the pedrete corona clara in Spanish. The yellow-crowned night heron is a rather stocky wading bird, ranging from 55 to 70 cm (1 ft 10 in – 2 ft 4 in) and from 650 to 850 g (1.43–1.87 lb), the females being a little smaller than the males. The yellow-crowned night heron has a wingspan ranging from 101 to 112 cm (3 ft 4 in – 3 ft 8 in). The neck, slim when extended, exposes its large head (compared to its body), with a large and heavy bill. (Source: Wikipedia.org, CC BY-SA)
