This colorful and elegant species, formerly called Louisiana Heron, is common in marshes along much of the East Coast of the U.S. Audubon's climate model predicts a 54 percent loss of current summer range by 2080, with some potential expansion well into the interior, particularly in the Mississippi Valley, an area well known for hosting wandering Tricolored Herons in late summer. Small numbers already nest in places like Oklahoma and Kansas, giving credence to the projection.
