Great Blue Herons forage primarily by walking slowly through water, often chest deep, and quickly striking their prey with their bill, which is adapted for both grasping and spearing. Like all other birds of the family Ardeidae the Great Blue Heron has an “S” shaped neck in which the bones of the neck are even more “S” shaped than the neck itself. This extra length of vertebrae serves two functions - (i) since the vertebrae cross from behind to in front of the esophagus, the bones can protect the esophagus during a strike and (ii) this added length allows for incredible quickness in the strike itself.
