NAME: ‘Heron’ would mean ‘to creak or screech’ (in reference to the bird’s call). Latin genus name ‘Nyctanassa’ means ‘queen of the night’. Latin species name ‘violacea’ means ‘violet’ and would refer to the color of the bird’s back.
HABITAT: Shallow wetlands (bayous, mangroves, swamps).
DIET: Crustaceans for the most part, hunts by day and by night. Can eat turtles, as its stomach is able to digest the shell.
NESTING: May nest in colonies, sometimes with Black-crowned Night Herons. Nest is a structure made of sticks lined with finer material and located in a tree, usually high above ground. Between three and seven light green-blue eggs are laid, incubated by both parents, who also both feed the nestlings.
DISTRIBUTION: Breeds mainly in southeast USA. Year-round population is found along the coasts of Mexico, Central and South America (except along the Andes and Argentina).

ON PEI: Does not breed on Prince Edward Island, sightings listed as ‘accidental’ (in the fall) so far. See note below on bird vagrancy.
CONSERVATION: Population appears stable, might be expanding range northward.
Vagrancy: In biology this means an animal going way outside its normal range. For birds, this can happen when there are storms and they get blown off course. On other times, the bird simply wanders in a different direction than usual. Here’s an article about vagrancy in birds.
