Black-crowned Night Herons are a major presence at the rookery next to the Welcome Center at Ocean City, NJ. These birds hunt for their food starting at dusk, and their eyes are one of their most noticeable features.
Despite their size these Herons are easily intimidated by the Red-winged Blackbird, a fierce defender of its territory. I saw a Blackbird chase a Heron into a tree.
Pursued by the Blackbird, the Heron tried to hide among the branches. Unfortunately, too many leaves shielded the small Blackbird from the camera.
