Eastern Cattle Egret

It was formerly lumped with the western cattle egret but the two are now separate species. It is white, with buff plumes in the breeding season, and is more closely related to the herons of Ardea than to the egrets of Egretta (Wikipedia, general species account). It uses drier, more open habitats than most herons and often accompanies cattle or other large mammals, catching insects and small vertebrates they disturb. (Wikipedia, general species account).

Eastern Cattle Egret is a heron found in the tropics, subtropics and warm temperate zones, native to southern and eastern Asia and Australasia. The species belongs to heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. The nest is a platform of sticks in trees or shrubs. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. (Wikipedia, general species account).
