The yellow-billed stork (Mycteria ibis) is a large African stork species in the family Ciconiidae. It is widespread south of the Sahara and also occurs in Madagascar. The yellow-billed stork lies within the genus Mycteria along with three other extant species: the wood stork (M. americana), the milky stork (M. cinerea) and the painted stork (M. leucocephala). Species within Mycteria display remarkable homologies in behavior (e.g., feeding and courtship) and morphology, with relatively few species-specific variations.
[[File:]] This medium-sized stork stands 90–105 cm (35–41 in) tall. Its body is white with a short black tail that is glossed green and purple when freshly moulted. The bill is deep yellow, slightly decurved at the end and with a rounder cross-section than in other stork species outside the Mycteria. Feathers extend onto the head and neck just behind the eyes, with the face and forehead being covered by deep red skin. Both sexes are similar in appearance, but the male is larger and has a slightly longer heavier bill. Males and females weigh approximately 2.3 kg (5.1 lb) and 1.9 kg (4.2 lb) respectively.

Likely
About 40% of wildlife watchers report a Yellow-billed Stork sighting in Nairobi National Park on a given day, based on 739 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 54th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
August to October
In those months about 60% of wildlife watchers report a Yellow-billed Stork in Nairobi National Park on a given day, against about 10% in June, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-billed Stork sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 38
Of the 38 parks where we can rate Yellow-billed Stork sightings, Nairobi National Park ranks 6th at about 40%. The best odds are in Lake Nakuru National Park (Kenya, about 70%), South Luangwa National Park (Zambia, about 60%) and Gonarezhou National Park (Zimbabwe, about 50%). All parks ranked.
Same family: Ciconiidae
The closest relatives of the Yellow-billed Stork that you can see in Nairobi National Park (family Ciconiidae, Storks) are Marabou Stork (about 50%), African Openbilled Stork (about 20%) and Black Stork (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-billed Stork is recorded against all the birds logged in Nairobi National Park (739 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.
