Physical 

Black-crowned night herons are stocky birds that often tuck their necks into their body, making them look hunchbacked. Adults have red eyes, a white belly, grey wings, and a black cap and back. Juveniles are brown with white streaks and a pale yellow bill.

Habitat

Black-crowned night herons live in marshes and along shores, in fresh and saltwater. They nest on every continent except Antarctica and Australia. Their range spans every state in the continental US, and while some migrate, black-crowned night herons stay in the Barnegat Bay year-round. They roost in trees, thickets, on islands, and over water.

Feeding 

Like their name suggests, black-crowned night herons feed in the evening and night. They perch at the water’s edge, or walk slowly searching for prey. They feed on fish, squid, crustaceans (shrimp), frogs, snakes, clams, mussels, rodents, and carrion.
