Least Bittern


IUCN Conservation Status: Least Concern

A tiny heron, furtive and surpassingly well camouflaged, the Least Bittern is one of the most difficult North American marsh birds to spot. Despite its inconspicuousness, however, the species can be rather common within appropriate habitat in its breeding range.
