The Herons are a Family of water birds characterised by their long neck, long legs and long bill. Close relatives are the bitterns and the egrets. This proud fellow is a Great Blue Heron from North America. He is one of the largest Herons in the world. His main diet is fish, although he will prey on a wide range of other animals species including small birds, rodents and other mammals, frogs and invertebrates. He hunts visually, sighting his prey then snapping it up in his bill, swallowing it whole. Herons have been known to choke on prey that is too large.
