Great Blue Heron flying low through Jungle Gardens on Avery Island.

Green Herons are considered among the world's most intelligent birds, because they sometimes drop food or insects on the water's surface to attract fish, making them one of the few species to use tools. They are generally nocturnal, and are not very tolerant of other birds. This Green Heron was photographed perched in the Buttonwood tree to the right of Bird City's observation platform, in Avery Island's Jungle Gardens.
