Great Blue Heron

Description:

I think this is a juvenile. "Largest of the North American herons with long legs, a sinuous neck, and thick, daggerlike bill. Head, chest, and wing plumes give a shaggy appearance. In flight, the Great Blue Heron curls its neck into a tight “S” shape; its wings are broad and rounded and its legs trail well beyond the tail. Color Pattern: Great Blue Herons appear blue-gray from a distance, with a wide black stripe over the eye. In flight, the upper side of the wing is two-toned: pale on the forewing and darker on the flight feathers. " - All About Birds

Habitat:

Small lake at park. They're "common near the shores of open water and in wetlands over most of North and Central America as well as the Caribbean and the Galápagos Islands. It is a rare vagrant to Europe, with records from Spain, the Azores, England and the Netherlands." - Wikipedia
