Off the heron goes again on its morning prowl. Behaviour and ecology
Foraging white-faced herons walk slowly with long, controlled steps, watching for any signs of prey, which is grabbed with lightning speed. When white-faced herons occur at high densities, e.g. on mudflats, aggressive displays may be directed to other herons that approach too close. Roosting white-faced herons perch in trees or on top of man-made structures such as street lights. They roost solitarily or occasionally as pairs. During courtship and nesting, white-faced herons raise their plumes, and they may perform aerial displays near the nest.
