Black-headed Heron

"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.
It often feeds in shallow water, spearing fish or frogs with its long, sharp bill. It will also hunt well away from water, taking large insects, small mammals, and birds. It will wait motionless for its prey, or slowly stalk its victim." (Wikipedia)
The black-headed heron is a large bird, standing 85 cm tall, and it has a 150 cm wingspan
