Western Cattle-Egrets I

“Cattle egrets are named as such because of their close relationship with cattle and other livestock. Cattle egrets are often found flocking around cattle and buffalo, using their backs as a perch. As cattle roam and graze the landscape, they disturb insect populations which the egrets swoop in and eat. This relationship is finely-tuned, as Cattle egret foraging success is much greater when they hunt in close proximity to a large grazing animal.”
