The distinctively loud and recognisable haa-haa-haa-de-dah call of the Hadada relates to its name. The call is one of the most typical and often heard in urban areas in Nairobi and other places in Africa. This common Ibis is found in many African countries and throughout open grasslands, savanna and wetlands, as well as urban parks, school fields, green corridors and large gardens. It feeds mainly on earthworms, using its long scimitar-like bill to probe soft soil. These birds also favour snails and will feed in garden beds around residential homes. They are particularly welcomed on bowling and golf greens because they are assiduous in extracting larvae of moths and beetles that feed on the roots of the grass.
