The African grey hornbill (Lophoceros nasutus) is a member of the hornbill family of mainly tropical near-passerine birds found in the Old World. It is a widespread resident breeder in much of sub-Saharan Africa and the southwest of the Arabian Peninsula. The African grey hornbill has escaped or been deliberately released into Florida, USA, but there is no evidence that the population is breeding and may only persist due to continuing releases or escapes.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the African grey hornbill in the fourth volume of his Ornithologie based on a specimen collected in Senegal. He used the French name Le calao à bec noir du Sénégal and the Latin name Hydrocorax Senegalensis Melanorynchos. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognized by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson in his Ornithologie. Linnaeus included a terse description of the African grey hornbill, placed... Wikipedia →

Possible
About 20% of wildlife watchers report an African Grey Hornbill sighting in Pretoria on a given day, based on 152 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 177 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report an African Grey Hornbill in Pretoria on a given day, against about 10% in April and June–August, the lowest months. That is one of Pretoria's wettest months, with about 90 mm of rain against almost none in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most African Grey Hornbill sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 13
Of the 13 cities where we can rate African Grey Hornbill sightings, Pretoria ranks 6th at about 20%. The best odds are in Accra (Ghana, about 60%), Maiduguri (Nigeria, about 40%) and Serrekunda (Gambia, about 40%).
Same order: Bucerotiformes
The closest relatives of the African Grey Hornbill that you can see in Pretoria (order Bucerotiformes, Hornbills and Hoopoes) are African Hoopoe (about 20%), Green Wood Hoopoe (about 20%) and Common Hoopoe (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Grey Hornbill is recorded against all the birds logged in Pretoria (152 verified sightings), 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.
