Great Blue Heron

Near shore, Gulf of Mexico.
"Individuals usually forage while standing in water, but will also feed in fields or drop from the air, or a perch, into water. As large wading birds, Great Blue Herons are able to feed in deeper waters, and thus are able to harvest from niche areas not open to most other heron species.
It feeds in shallow water or at the water's edge during both the night and the day, but especially around dawn and dusk. It uses its long legs to wade through shallow water, and spears fish or frogs with its long, sharp bill."-Wikipedia
