The hadeda is a large African bird from the ibis family. It has gray plumage with a metallic sheen on the wings and a long curved beak.
The hadeda differs from other ibises in its gray body color and loud cry that sounds like 'ha-da-da'. It is beneficial for nature because it eats many harmful insects and worms.
