Behaviour

They are highly social birds that roost communally in trees during the day and become active hunters at dusk, using a patient sit-and-wait hunting strategy to ambush fish, frogs, and invertebrates.

Native Range

The black-crowned night heron is found throughout a large part of the world, including parts of Africa Asia Europe and North and South America.

Did You Know?
