Migratory Bird of the Day: Black-crowned Night-Heron
While birdwatching at your local wetland, you are most likely to see the Black-crowned Night-Heron perched on trees near the water during the day. As the sun sets, it becomes active searching for food and calling out “Woc” or “Quock.”
Scientists think they feed at night when competition for food is low, since other herons and egrets feed during the day. But they are not picky eaters and will feed during the day in the breeding season. They eat a variety of foods including leeches, earthworms, insects, crayfish, clams, fish, frogs, snakes, eggs, carrion, plants, and even garbage from landfills!
The Black-crowned Night Heron is a medium-sized stocky heron with a short neck and legs – giving it a hunched appearance. Adults have a white head with a distinctive black cap and upper back. Wings, rump, and tail are gray with white to pale gray underparts. Eyes are red and legs yellow-green. During the breeding season, their yellow-green legs turn pink, they develop long white head plumes, and the black on the head and back acquires a blue-green gloss. Juveniles are noticeably different – brown all over with white flecks and yellow eyes.
There are resident populations of Black-crowned Night-Herons on many Caribbean islands, including the Bahamas, Greater Antilles, Virgin Islands, Cayman Islands, and possibly Barbados. The breeding season varies from as early as January to as late as August. Like many herons they nest in colonies. Males choose the nest site up in a tree and begin to build the twig and stick nest, which they then advertise to prospective mates. Colonies in good locations, free from predators and other disturbances, may be used for 30-50 years!
During fall and winter Black-crowned Night-Herons from colder climates migrate south. Some will travel from as far as Massachusetts or Alberta to spend winter in Florida, Mexico and the Caribbean. Mudflats, shallow ponds, creeks, swamps, and marshes are important areas for this bird and should be protected. Black-crowned Night-Heron may even be able to tell you how healthy these areas are. Because they are high-up in the food chain, have a widespread distribution, and are colonial nesters, they make excellent environmental indicators of contamination.
