The southern yellow-billed hornbill (Tockus leucomelas) is a hornbill found in southern Africa. Yellow-billed hornbills feed mainly on the ground, where they forage for seeds, small insects, spiders and scorpions. This hornbill species is a common and widespread resident of dry thornveldt and broad-leafed woodlands. They can often be seen along roads and water courses.
It is a medium-sized bird, 48–60 cm (19–24 in) in length, 132–242 g (0.29–0.53 lb) in weight and is characterized by a long yellow and down-curved beak. This beak is huge in comparison to its body and can account for up 1/6th of the entire body length. Male beaks are on average 90 mm long while female beaks are an average of 74 mm. Males are generally bigger than females but there is overlap between the sexes. The size difference of the beak is a fairly reliable way of differentiating sex in wild hornbills.
The casque that characterizes all hornbills is of a very modest size in the southern yellow-billed hornbill. It is small, but it covers almost the entire length of the beak in males (less so in females), and may give the impression that they do not actually have a casque. As in all hornbills, the...

Possible
About 20% of wildlife watchers report a Southern Yellow-billed Hornbill sighting in uMkhuze Game Reserve on a given day, based on 105 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 136th most-seen of the 283 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Southern Yellow-billed Hornbill in uMkhuze Game Reserve on a given day, against about 10% in June and September–December, the lowest months. That is one of uMkhuze Game Reserve's driest months, with about 15 mm of rain against 120 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Southern Yellow-billed Hornbill sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 12
Of the 12 parks where we can rate Southern Yellow-billed Hornbill sightings, uMkhuze Game Reserve ranks 10th at about 20%. The best odds are in Gonarezhou National Park (Zimbabwe, about 70%), Hwange National Park (Zimbabwe, about 60%) and Kruger National Park (South Africa, about 60%). All parks ranked.
Same family: Bucerotidae
The closest relatives of the Southern Yellow-billed Hornbill that you can see in uMkhuze Game Reserve (family Bucerotidae, Hornbills) are Trumpeter Hornbill (about 50%) and Crowned Hornbill (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Yellow-billed Hornbill is recorded against all the birds logged in uMkhuze Game Reserve (105 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.
