Pair of adult green-backed herons (Butorides virescens) in the nest with their two chicks. A green heron pair usually sites their nest in a dense tree or shrub over water, sometimes on an island emerging from a small wetland or drainage pond. Rarely, these birds nest on the ground. The male begins the stick platform, which the female finishes before laying usually three to five green or blue-green eggs. Photographed near Maquenque Lodge, Costa Rica.
