Great Blue Heron – St Marks National Wildlife Refuge
Great Blue Heron Ardea herodias are the largest of the North American herons. They inhabit shorelines, river banks, and the edges of marshes, estuaries, and ponds across most of North America. "Because Great Blue Herons depend on wetlands for feeding and on relatively undisturbed sites for breeding, they are vulnerable to habitat loss and to impacts such as traffic, logging, motorboats, and other human intrusions that can disrupt nesting colonies. Other threats include chemical pollutants or other causes of reduced water quality."1
