The hadada ibis (Bostrychia hagedash) or hadeda is an ibis 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, foraging in cultivated land and gardens. A medium-sized ibis with stout legs and a typical down-curved bill, the wing coverts are iridescent with a green or purple sheen. They are non-migratory but are known to make nomadic movements in response to rain particularly during droughts. Their ranges in southern Africa have increased with an increase in tree cover and irrigation in human-altered habitats.
Tantalus hagedash was the scientific name proposed by John Latham in 1790 who described it from a specimen that had been collected at "Houteniquas", due north of Mossel Bay, by Anders Sparrman who also recorded that it was onomatopoeically "called by the colonists hagedash, and also hadelde." It was later placed in a monotypic genus as Hagedashia hagedash but has since been placed... Wikipedia →

Likely
About 60% of wildlife watchers report a Hadada sighting in Arusha National Park on a given day, based on 465 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 373 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
February–April and November–December
In those months about 70% of wildlife watchers report a Hadada in Arusha National Park on a given day, against about 50% in June and September, the lowest months. Those are among Arusha National Park's wettest months, with about 230 mm of rain a month against 65 mm in September.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Hadada sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 52
Of the 52 parks where we can rate Hadada sightings, Arusha National Park ranks 7th at about 60%. The best odds are in Niokolo-Koba National Park (Senegal, about 70%), Nairobi National Park (Kenya, about 70%) and Addo Elephant National Park (South Africa, about 70%). All parks ranked.
Same family: Threskiornithidae
The closest relatives of the Hadada that you can see in Arusha National Park (family Threskiornithidae, Ibises and Spoonbills) are African Sacred Ibis (about 50%), Glossy Ibis (about 10%) and African Spoonbill (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hadada is recorded against all the birds logged in Arusha National Park (465 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
