|From Lake Naivasha, Kenya|
The Hadeda is a large (about 76 cm long), grey-to-partly brown species of ibis. It has a narrow, white, roughly horizontal stripe across its cheeks. This is sometimes called the "moustache" though it does not reach the mouth corners. The plumage over the wings has an iridescent purple sheen. The bird has blackish legs and a large grey-to-black bill with a red stripe on the upper mandible. The upper surfaces of the toes are of a similar red.
It has a distinctively loud and recognisable haa-haa-haa-de-dah call that is often heard when the birds are flying or are startled, hence the name.
Habitat and distribution 
The Hadeda Ibis is found throughout open grasslands, savanna and wetlands, as well as urban parks, school fields, green corridors and large gardens. The countries that this bird occurs in are Sudan, Ethiopia, Senegal, Uganda, Tanzania, Gabon, Democratic Republic of Congo, Cameroon, Gambia, Kenya, Somalia and South Africa.
It feeds mainly on earthworms, using its long scimitar-like bill to probe soft soil. It also eats larger insects, such as the Parktown Prawn, as well as spiders and small lizards. 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. It is not clear how they detect these, but it seems likely that they can hear their chewing and digging.
