Black Crowned Night Heron Nycticorax nycticorax in Dallas County Texas April 21, 2013. This particular Black-Crowned Night Heron is in the midst of preparing a nesting site to lay eggs during breeding season. The birds in this area feed in shallow drying pools along the Trinity River where floodwaters have left numerous bait fish and aquatic food for the birds to eat.

The black-crowned night-heron breeds on every continent except Australia and Antarctica. They are one of the more common herons in the United States, breeding everywhere except the southwest and Rocky Mountain states. They are found in many types of wetland habitats including riparian forests, wooded swamps, marshes, mangroves, and even occasionally grasslands or rice fields.
