Easy access to insects flushed out by the cattle

The benefit of the cattle egret for foraging close to grazing cattle is (a) Easy access to insects flushed out by the cattle.

Explanation: Cattle egrets forage close to grazing cattle because as the cattle move, they stir up and flush out insects from the vegetation.

The egrets take advantage of this behavior to easily access the insects that would otherwise be difficult for them to find and catch.

By foraging near the cattle, the egrets have a reliable source of food, as the movement of the cattle disturbs the insects, making them more accessible for the egrets to feed on.

Therefore, the benefit of the cattle egret's proximity to grazing cattle is the easy access to insects flushed out by the cattle.
