Africa south of the Sahara and Madagascar
Inhabits marshes and shores
Sacred ibis live in large colonies near waterways throughout Africa.
Ibises have curved, slender bills that they use to probe into shallow water, mud or grass when foraging.
This is a gregarious bird, living, traveling, and breeding in flocks. In flight, ibises form diagonal lines or v-formations. This formation decreases wind resistance for trailing birds. When the leader of the pack tires, it falls to the back of the formation and another ibis takes its place at the front.
Ibises are rather quiet birds, only grunting or a croaking on breeding grounds.
In ancient Egyptian societies, the sacred ibis was worshipped as the god Thoth and was supposed to preserve the country from plagues and serpents. The birds were often mummified and then buried with pharaohs.
Both the male and female take turns in guarding the nest site until the chicks are large enough to defend themselves. In addition, both parents help feed the chicks.
Ibises are an ancient species with fossil records going back 60 million years.
ECOLOGY AND CONSERVATION
The sacred ibis, so important in ancient Egyptian culture, is now extinct in Egypt. Habitat destruction, poaching, and insecticide use such as DDT have all caused the decline of several ibis species.
These birds are not only scavengers, seen around rubbish dumps or sewage works, but they also move around croplands helping egrets and others to rid the area of insect pests. Its adaptability to several food sources ensures its success as a species.
Because of their role in helping to control crop pests, they are very valuable to farmers. However, agricultural pesticides usage has endangered the birds in several locations.
