Commensalism relationship is shown between cattle egret and cattle.
Usually cattle egrets follow herds of large hoofed mammals such as cattle, buffalo. They eat the insects that have been stirred up by the buffalo as they move. This relationship is commensalism, because the birds benefit but the ungulate is neither harmed nor helped.
The cattle egret and grazing cattle in a close association is a classic example of commensalism. It is a common sight in rural areas where one can see ticks hovering over the cattle. They feed on cattle's blood and hence are harmful to them as they can transmit several diseases. The cattle egret and grazing cattle in a close association is a classic example of commensalism.

<h3>What are species?</h3>
The species represent the lowest and narrowest taxonomic categories as far as the classification of living organisms is concerned.
A species represents a group of organisms whose mating will lead to the production of valid offspring.
Thus, no two different organisms can bear the same species name unless they can mate and produce fertile progenies.
What the mountain zebra and the donkey share is the genus name, not the species name. Different species of organisms can bear the same genus name as far as taxonomy is concerned.
