The diet of chicks was investigated in an intensively managed farmland in South Africa, after a prolonged drought, during the second brood (February/March). In comparison with other African studies, a larger proportion of frogs (mainly juvenile Pyxicephalus adspersus frogs) and a smaller proportion of grasshoppers (locusts and crickets) was recorded. This may have been due partly to exceptionally low rainfall rather than to different habitat or geographical location. The large proportion of locusts and flies in the diet indicates that the Cattle Egret may play an important role in pest control.
