The Sacred Ibis is black and white. All of its feathers are white except for tail and wing tips. Naked head and neck, legs, and feet are black. Ibises have long legs and long decurved (down-curved) bills. They are closely related to spoonbills. The Hadada Ibis and the Sacred Ibis are similar in size–about 30 inches long. Males and females of each species are similar in appearance.
- Sacred Ibises are generally silent but sometimes voice a harsh croak.
- Ibises usually roost in temporary communal roosts located near feeding grounds. They may share the roosting areas with herons, cormorants, storks or other ibis species.
