But sometimes herons will nest alone. They nest in trees and brushes, especially loblolly pine, beach, oak, and sycamore trees. Nests are made of sticks and lined with reeds, moss and grass. A mother will lay 3-7 eggs. When the eggs hatch the mother and father take turns feeding and guarding the chicks until they are old enough to care for themselves.
Juveniles leave the nest after one month.
Take part in efforts to protect and clean up wetlands and ocean areas. When these areas are polluted or destroyed herons have no place to build nests or find food. Pick up all litter, especially broken glass, plastic bags, kite strings, and fishing lines and tackle. These items can hurt and can kill great blue herons and other birds and mammals. Clean up after your dogs.
