The Cattle Egret is the most terrestrial heron; widespread and remarkably adapted to many habitats, both terrestrial and aquatic. Best described as a species adapted to naturally disturbed as well as to highly disrupted, converted landscapes, such as typical cattle and farm land and urban areas (parks, school grounds, sports fields, road edges, lawns, and city dumps and refuse areas) (Telfair II 1994).
Diverse diet which varies greatly according to foraging habitat, feeding opportunity, and prey availability. Mostly grasshoppers, crickets, spiders, flies, frogs, and noctuid moths (Telfair II 1994).
Nests in multi-species colonies established by native herons, egrets, ibises etc. and uses a wide variety of sites and substrates. Nests in live and dead vegetation. Eggs typically subelliptical, light sky blue in color. Clutch size ranges 1 to 9 eggs, averaging 3 to 4. Most first broods occur from early May to early June, depending on weather conditions (Telfair II 1994).
