Why do buffalo and egret stand together?

Are they good friends? They live a leisurely life together!

The gadfly, bigger than a fly, likes to bite buffalo and suck cow blood. It is the enemy of buffalo in summer. In the stable, the owner lights mosquito-repellent incense at most to drive away the gadfly, but the egret can eat the gadfly on the buffalo and let the buffalo rest comfortably. The natural biological chain constitutes a harmonious ecological beauty.
