The great blue heron is a native of North America. Among all living herons, it has been surpassed in size by only the goliath heron (Ardea) and the great white heron.
It exhibits a minor degree of sexual dimorphism, with males being slightly larger than females. However, the two sexes don't seem to be externally distinguishable and to the naked eye, a male and female bird of this species look relatively the same.
Males are a bit larger, with longer decorative plumes on their heads and necks. Breeding pairs are only seen together when they're in the nest while they are raising their young. They rest in a sheltered spot by folding up their neck and sitting quietly during the daytime. Meanwhile, at night, they sleep in trees.
