Ardea melanocephala (Black-headed Heron)

Wikipedia Abstract

The black-headed heron (Ardea melanocephala) is a wading bird of the heron family Ardeidae, common throughout much of sub-Saharan Africa and Madagascar. It is mainly resident, but some west African birds move further north in the rainy season. This species usually breeds in the wet season in colonies in trees, reedbeds or cliffs. It builds a bulky stick nest, and lays 2–4 eggs. The call is a loud croaking.
