  Least Bittern
The Least Bittern is one of the smallest herons in the world, and the smallest in North America.
The Least Bitterns share a number of traits with the larger American Bittern: cryptic coloration, stealthy habits that generally keep them hidden, and a preference for marshes with dense emergent vegetation.
Although bitterns are usually the most solitary of herons, clusters of Least Bittern nests may be found in appropriate habitat with especially good food supplies.
