黑鹭在博茨瓦纳莫雷米游戏保护区的奥卡万戈三角洲浅水区捕鱼，用翅膀制造阴影。

ck heron, also known as the black egret, is an African heron. It uses its wings to form a canopy when fishing. The black heron, a jet-black bird found in southern Africa and Madagascar, has devised a devilishly clever way to catch its prey. When hunting for small fish in shallow water, the black heron uses its wings like an umbrella to create a patch of shade beneath it.
