Great Blue Heron


In and around fish-bearing waterways.


In deciduous, coniferous, or mixed woods, usually in small colonies. A flattish nest is made of twigs and small branches in the upper parts of tall trees.

  • Eggs, 3 – 5; light greenish-blue.
  • The incubation period is 26 – 27 days.


The Great Blue Heron’s long, stilt-like legs allow it to wade in shallow waters to feed on a diet of fish, frogs, and water snakes. It will also eat salamanders, large insects, mice, and other small rodents.

The song of the Great Blue Heron is a goose-like Onk.
