CATTLE EGRET Bubulcus ibis
Despite originating in Africa, the adaptable Cattle Egret has managed to increase its distribution on the back of extensive cattle ranching to become almost a cosmopolitan species. The first individuals arrived in South America in Brazil in the early 1960s, but it is now one of the most widespread species on the continent often seen perching on the backs of cattle as they graze. Non-breeding birds are wholly white, while breeding birds adopt buffy-cinnamon patches on the crown and breast.
