As a vagrant in western Europe, distinguished from Eurasian Bittern by its somewhat smaller size, brown not black crown, black neck stripe, and more rufous-brown (not yellow-buff) tones, particularly on the neck.
Distribution
Breeds from southeastern Alaska, Manitoba, and Newfoundland south to California, New Mexico, Arkansas, and South Carolina. Winters from coastal British Columbia, Southwest, Illinois, and along Atlantic Coast to Long Island (occasionally farther north), and south to Costa Rica (rarely) and Greater Antilles. A rare autumn to winter vagrant to western Europe, with most of the records from Iceland, Ireland, Great Britain, and the Azores.
Taxonomy
This is a monotypic species[1].
Habitat
Freshwater and brackish marshes and marshy lakeshores; regular in salt marshes during migration and winter.
Behavior
Breeding
2-6 buff or olive-buff eggs placed on a platform of reeds concealed in a marsh. Does not nest in colonies.

Flight call a low kok-kok-kok.
