The most geographically widespread heron, appearing on all continents except Australia and Antarctica, is the Black-crowned Night Heron. They have a tongue twister of a scientific name Nycticorax nycticorax, meaning night raven. They are most often seen along the banks of rivers and streams sitting motionless, waiting for a fish to swim by. Unlike the Great Blue Heron they don't use their bill to stab prey, instead they grasp it. They eat fish but also a variety of other foods like frogs, snakes, rodents, invertebrates, and eggs. In Kentucky they are migrants, showing up in spring and leaving in the fall.
A simple heron to identify, the Black-crowned Night Heron can only be confused with the similar Yellow-crowned Night Heron. Both birds are roughly the same size and both have red eyes, but the Black-crowned has a black cap and back. The wings are gray and underparts are white. Sexes are the same but the immature is a mottled brown with much streaking on the breast and belly and a yellow eye instead of red.
