Great Blue Heron
Great Blue Herons are monogamous during mating season but choose new mates every year. Mating rituals include stick sharing and a dance. The dance includes puffing out chest feathers and touching bill tips. They will have anywhere from 2 to 6 eggs in a brood and 1 to 2 broods a year. The oldest known great blue heron was over 24 years old.
