An alert Green Heron hunts for fish in New York. These small herons hunt day and night, crouching patiently to surprise fish with a snatch of their dagger-like bill. They sometimes lure in fish using small items such as twigs or insects as bait. Unlike larger herons, Green Heron usually don’t wade, but rather hunt in shallow water, from solid ground, or when standing on vegetation.
