23-3-2018 BOULDER BEACH, CAPE TOWN - HADADA IBIS (Bostrychia hagedash)
The Hadada Ibis, Bostrychia hagedash, is a medium-sized bird native to the diverse landscapes of Sub-Saharan Africa. It is characterized by its stout legs and distinctive down-curved bill. The adult Hadada Ibis typically measures around 76 cm in length and weighs approximately 1.2 kg. Both sexes share similar plumage, which is primarily grey to partly brown, with a striking iridescent sheen of green or purple on the wing coverts.
When observing the Hadada Ibis, look for the narrow white stripe across its cheeks, often referred to as the "moustache," though it does not extend to the mouth corners. During the breeding season, the bird sports a red culmen on the upper mandible's basal half and similarly colored upper toe surfaces. Its powerful and broad wings facilitate quick take-offs and agile flight through dense foliage.
The Hadada Ibis thrives in a variety of habitats, including open grasslands, savannas, wetlands, and increasingly in urban environments such as parks, school fields, and residential gardens. It prefers areas with moist and soft soils, which are conducive to its foraging habits.
This species is widespread across Sub-Saharan Africa, with its range extending from Sudan to South Africa. The Hadada Ibis has seen a notable range expansion in southern Africa, attributed to increased tree cover and irrigation in human-altered landscapes.
The Hadada Ibis is known for its social roosting behavior, often in groups atop trees. It is a diurnal bird, vocalizing loudly during morning and evening flights. Its diet consists of insects, millipedes, earthworms, and other small invertebrates, which it hunts using its long, scimitar-like bill to probe the soil. The Hadada Ibis is also appreciated in urban settings for its role in controlling pests on lawns and greens.
The Hadada Ibis is renowned for its loud "haa-haa-haa-de-dah" call, which is particularly prominent during flight or when startled. This call has earned the species its onomatopoeic name. While roosting, a single loud "haaaa" can be heard, and a low growl, akin to a young puppy's, serves as a contact call when foraging.
Monogamous by nature, Hadada Ibises maintain pair bonds year-round. Breeding is timed with the rainy season, with nests constructed as twig platforms in large trees. Both parents incubate the typical clutch of three to four eggs for about 26 days, and the fledglings leave the nest after approximately 33 days.
The Hadada Ibis can be distinguished from other ibis species by its unique vocalizations, the iridescent sheen on its wings, and the red coloration on its bill and toes during the breeding season.
Hadada Ibises primarily feed on soil invertebrates, which they detect using sensory pits around their bill tips. They are also known to consume snails and small reptiles, providing a natural pest control service in both natural and urban settings.
The IUCN Red List classifies the Hadada Ibis as Least Concern due to its extensive and common presence throughout its large range. The species has adapted well to human-modified environments, contributing to its stable population status.

14-10-2015 VALENCIA BIOPARC - HADADA IBIS (Bostrychia hagedash) NIKON P900
The Hadada ibis (Bostrychia hagedash) is a long-legged wading bird native to Sub-Saharan Africa. It is named for its loud three to four-note calls uttered in flight especially in the mornings and evenings when they fly out or return to their roost trees. Although not as dependent on water as some ibises, they are found near wetlands and often live in close proximity to humans.
Hadada ibises are large grey-to-partly brown birds. Males and females are alike in plumage. They have a narrow, white, roughly horizontal stripe across their cheeks. This is sometimes called the "mustache" though it does not reach the mouth corners. The plumage over the wings has an iridescent purple sheen produced by optical microstructures within the feathers. Hadada ibises have blackish legs and a large grey-to-black bill but during the breeding season, they have a red culmen on the basal half of the upper mandible. The upper surfaces of their toes are of a similar red during the onset of breeding. The wings are powerful and broad, enabling quick take-offs and easy maneuvering through dense tree cover.
