These large birds can thrive in a range of habitats from forests to urban areas, although they usually nest near water. This ranges in type from rivers and seas to lagoons and even sewage works. Some populations migrate within Africa during rainy seasons to breed. Individuals fly up to 30km away from their nesting colony in search of their preferred diet of insects, but they can also feed on crustaceans, fish and small mammals which they find by wading in shallow wetlands.
