The Great Blue Heron is the largest and most common Heron in the North America. In the county they can be seen just about everywhere there is water. I’ve seen them at the Beach and at all the Wetlands. I’ve seen them along the many, many miles of Canals and at little lakes in housing developments.
A couple of interesting facts about Great Blues are they are one of the few birds that hunts both during the day and at night. They feed primarily on fish, frogs and snakes but in some parts of the country mice and other small mammals make up as much as 40% of their diet.
In Palm Beach County they nest regularly at Wakodahatchee Wetlands. They generally nest twice a year in Nov/Dec and then again in Apr/May. Wakodahatchee has had as many as 6-10 pairs nesting at any one time.
Great Blues can live up to 15 years in the wild but the average is between 6 and 8 years.
