No they are insectivorous.
Egrets and the mouths of herbivores have a mutualistic relationship called commensalism. Egrets often follow herbivores, such as cows or buffaloes, and eat the insects that get disturbed as the herbivores graze. While the egret benefits by getting an easy meal, the herbivores are unaffected by the presence of the egret.
mutualism
Cattle egrets Bubulcus ibis do benefit from their symbiosis (Relationship) with cattle. The symbiosis that they share is commensalism, one animal (The cattle Egret) benefits, while the Cattle is unaffected. The cattle help the egrets by disturbing small invertebrates that the Cattle egret eats.
commensalism
egrets eat flies or what everother bug is ona cow
Both the Cattle egrets and the ungulate Mammal herds are benefiting from both relationship. The Cattle egrets get a to have a free meal. The Cattle are free of ticks and unwanted parasites.
mutualism
In areas where both animals live, the egrets feed on insects that are attracted to the cattle. This is a symbiotic relationship because both parties benefit and neither is harmed - the cattle have fewer insects bothering them and the egrets have easily obtained meals.
The relationship between cattle egrets and cape buffalo would not be commensalism if the egrets removed ticks from the buffalo, because both species would benefit. The buffalo would be tick free and the egrets would have food to eat.
It is a Commensalism relationship
No. Cattle are herbivores.
Cattle Egrets foraging in fields among cattle or other livestock. As cattle, horses and other livestock graze on the field; they cause movements that stir up various insects. As the insects are stirred up, the Cattle Egrets following the livestock catch and feed upon them. The egrets benefit from this relationship because the livestock have helped them find their meals, while the livestock are unaffected by it.
