A friend sent me a message along with a single image. “The river has been taken over by herons. Is it common for them to gather in such high density?” I was astonished when I looked at the picture! Indeed, a large number of herons were gathered along the riverbank.
In fact, herons, particularly the Great Egret species, tend to flock together where their white-feathered companions are. This is because having many members in a group makes it more efficient to catch food. When the herons move all at once, frogs and fish get startled and come out, making it a feast for the entire group.
Herons are also visually unique, each species possessing its own charming characteristics. From the Grey Heron, resembling a modern pterosaur, to the elegant Little Egret, often found near water, and the Intermediate Egret, adding a touch of summer to the rice fields, watching these birds is never dull.
However, coexisting with herons requires a bit of ingenuity. Recently, they have started to form colonies near residential areas, sometimes causing damage to the local lifestyle. To live harmoniously with them, it is crucial to maintain a respectful distance while striving to learn more about their ecology.
And be mindful of the cormorants! In winter, they migrate inland in search of river fish. Their mass movement is quite a sight, creating a memorable spectacle.
For a joyful coexistence with the herons, let’s continue to cherish and protect them!
