The Cattle Egret (Bubulcus ibis) is an
abundant, widespread heron that occurs in both Africa and South America, as
well as on all other continents. It colonized Fernando de Noronha
during the final years of the twentieth century, and has a large nesting colony on one of the islets.
The Cattle Egret is the least aquatic of all members of the heron family and
forages in a wide variety of habitats, from wetlands and pastures to semi-arid
steppe (Martínez-Vilalta and Motis 1992). It is often seen feeding in
flocks and frequently associates with domestic cattle.
Egret's ability to
cross water gaps and invade distant lands is legendary, well-illustrated by
the fact that it has colonized many islands in the "Pacific, Atlantic and
Indian Oceans, and even turns up regularly in the Antarctic (Martínez-Vilalta
and Motis 1992)."
