With a range that spans five continents, including much of North America, the Black-crowned Night-Heron is the most widespread heron in the world. It is most active at dusk and at night, feeding in the same areas that other heron species frequent during the day.

Short neck and thick black bill.
Black cap and back.
Wings gray.
Underparts white.

Size: 58-66 cm (23-26 in)
Wingspan: 115-118 cm (45-46 in)
Weight: 727-1014 g (25.66-35.79 ounces)
Sex Differences
Sexes similar; female slightly smaller.

Call a loud, harsh squawk.

Conservation Status
Overall, populations stable. Because of wide distribution and feeding habits, the Black-crowned Night-Heron is an excellent indicator of ecosystem health. You can help scientists learn more about this species by participating in the Celebrate Urban Birds! project.

Other Names
Bihoreau couronne noire (French)
Yaboa real, Guanaba, Guaco (Spanish)

Cool Facts

Young Black-crowned Night-Herons often disgorge their stomach contents when disturbed. This habit makes it easy to study its diet.

The Black-crowned Night-Heron may nest in the same tree with ibises or other herons.

Adult Black-crowned Night-Herons apparently do not distinguish between their own young and those from other nests, and will brood chicks not their own.
