The western long-tailed hornbill (Horizocerus albocristatus) is a species of hornbill (family Bucerotidae) found in humid forests of West Africa. It was formerly considered to be conspecific with the eastern long-tailed hornbill (Horizocerus cassini) with the English name "white-crested hornbill".
The western long-tailed hornbill was formally described in 1848 by the American ornithologist John Cassin based on a specimen that had been collected near the Saint Paul River in Liberia. He coined the binomial name Buceros albocristatus. The specific epithet combines the Latin albus meaning "white" with cristatus meaning "crested" or "plumed". The species is now placed in the genus Horizocerus that was introduced in 1899 by the American ornithologist Harry C. Oberholser. The western long-tailed hornbill was formerly considered to be conspecific with the eastern long-tailed hornbill (Horizocerus cassini) with the English name "white-crested hornbill".
There are two subspecies, which differ primarily in the amount of white to their head and neck and the presence or absence of white tips to the wing-coverts: H. a... Wikipedia →

Possible
About 30% of wildlife watchers report a White-crested Hornbill sighting in Semuliki National Park on a given day, based on 134 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 48th most-seen of the 280 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
October
In that month about 50% of wildlife watchers report a White-crested Hornbill in Semuliki National Park on a given day, against about 20% in February and November–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-crested Hornbill sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate White-crested Hornbill sightings, Semuliki National Park has the highest daily chance: about 30%. Next come Taï National Park (Ivory Coast, about 20%).
GBIF citizen-science records
It is estimated from how often the White-crested Hornbill is recorded against all the birds logged in Semuliki National Park (134 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.
