Cattle Egret

• comportamientoIt follows large savanna herbivores closely to feed on the insects they stir up as they walk, a mutually beneficial relationship that is uncommon between birds and mammals.
• It follows cattle and large wild herbivores to catch the insects they flush as they graze; hence its common name in almost every language.
• Since the beginning of the twentieth century it has colonised almost the whole planet under its own steam, setting out from Africa and southern Europe.
• A study in Australia showed that it significantly reduces the number of flies biting cattle.
