Here are the details of their commensalism relationship:
1. Cattle Disturb Prey: The presence of cattle can flush out grasshoppers, flies, beetles, and other insects known as flush prey from their hiding spots in the grass as they move through open pastureland. These insects are the cattle egret's primary food source.
2. Following the Cattle: Cattle egrets follow cattle closely as they graze and watch the grass for these grasshoppers and insects. Cattle disturbance increases insect availability, making foraging more efficient for the egrets.
3. Reduced Energy Expenditure: Cattle egrets conserve energy by associating with large grazers like cattle, as they find more food with less effort. The disturbed prey is easier for the egrets to locate and capture.
4. Protection from Predators: While egrets are usually wary of predators, the cattle's size can provide some level of protection or early warning of potential threats, allowing the egrets to take flight and escape.
It's important to note that the cattle-cattle egret relationship is primarily beneficial to the cattle egret. While cattle are indifferent to the presence of the egrets, they neither gain nor lose anything substantial from the interaction. Therefore, this relationship is often categorized as commensalism.
