Least Bittern

About the Least Bittern

Also known as: Cory's Bittern, Cory's Least Bittern

The Least Bittern is a very small species of heron found in marshy habitats in the Americas. It feeds on small fish and insects that it hunts from a perched position among reeds standing in water.

Least Bitterns are often elusive. They spend their time in concealing vegetation, straddling and walking around reeds. If threatened, they freeze in place and may stand erect with the bill pointed straight up. In this way they resemble the reedy vegetation in which they are hiding.
