What is the relationship of egret and carabao?

Egrets and carabaos have a mutualistic relationship. Egrets are birds that feed on insects, while carabaos are large water buffalo that graze on grass. When carabaos graze, they stir up insects from the ground, which the egrets then eat. This benefits both the egrets and the carabaos, as the egrets get a source of food and the carabaos get rid of some of the insects that bother them.
