There are two types of night-herons in North America. The Black-crowned Night-Heron is the most abundant and widespread and its' habitat covers most of the USA, with some southern locations in Canada. The Yellow-crowned Night-Heron has a smaller range which covers the eastern portions of the USA and has occasionally been reported seen in Canada.
These two species of night-herons feed mainly at night. In the daytime they can be found dozing in marshes or standing on logs or rocks. These birds will also fly up into trees to avoid predators or to sleep. Like most other night-herons, these birds give loud squawks when alarmed.
