Hadada Ibis

The Hadada Ibis is one of the most familiar birds across sub-Saharan Africa, having adapted readily to gardens, golf courses, and urban parks. It is named onomatopoeically for its loud "ha-ha-ha-hadada" call, frequently given in flight at dawn and dusk. While its body plumage is unassuming grey-brown, the wing coverts carry a striking metallic sheen that reveals itself in good light.

• Body contour feathers are matte grey-brown with little pattern, appearing dull and plain when found on their own.
• Wing covert feathers show a bold, glossy patch of iridescent bronze-green shifting to purple, edged with a thin white or pale line in some individuals - the single best clue to identify this species from a feather.
• Flight feathers (primaries and secondaries) are dark grey-brown without the strong iridescence seen on the coverts.
• The head and neck feathers are shorter and duller, lacking the bare skin patches of some other ibises.
• Distinguish from glossy ibis, which shows iridescence across the entire body rather than confined mainly to a wing patch, and from Straw-necked Ibis, which has white underparts.

Adults are uniformly grey-brown with the diagnostic glossy wing-covert patch, a whitish stripe above the lores, and a long, downward-curving dark bill often marked with a reddish stripe along the upper ridge. Sexes look alike. Juveniles are duller and browner with less-developed iridescence on the wing coverts, brightening as they mature. Molt occurs gradually through the year without a sharply defined seasonal pattern in most tropical populations.

Hadada Ibis range across sub-Saharan Africa in savanna, open woodland, riverine forest edges, and increasingly in suburban gardens, parks, and golf courses where irrigation keeps the ground soft for foraging. Most populations are resident, with only local movements tied to rainfall and food availability rather than long-distance migration.

This ibis forages by probing soft, damp soil and lawns with its long bill for earthworms and other soil invertebrates, often working in small groups on open ground. It nests in trees, building a stick platform, and is not strongly colonial compared to some ibis relatives. Its far-carrying, cackling call is one of the most recognizable bird sounds in African towns and cities, frequently given in flight. It has adapted exceptionally well to human-altered landscapes, becoming a common urban and suburban species.
