Heron

Herons are extremely large species of birds that are natural predators to amphibians.

Appearance
They are very large, one toad being the size of its toe, and mostly white and light grey. Their beaks are purple and lined with razor-sharp teeth, the color getting lighter to the front of the beak. Their crest and eye-ring are a dark teal color, and they have two red eyes with black pupils. They have long legs and sharp talons.

Trivia

 * In the human world, herons are one of the apex predators to amphibians, similar to Amphibia.
 * In their debut in "Prison Break" the herons arrived in a pair rather than individually.
 * Sprig and Polly's parents were killed by a pair of herons when they were younger during an attack on Wartwood, though unconfirmed whether or not they were the same birds from "Prison Break".
