5 thoughts on “Black-casqued Hornbill (Ceratogymna atrata)”
Between the Copenhagen Zoo and Monitor Conservation Research Society we have observed an increase in trade with hornbill skulls for docoration and curiosity purposes. Investigations and data collection is still ongoing but black-casqued hornbill skulls are offered in quantity in USA, EU and as far away as New Zealand. A recent confiscations in Nigeria included over 370 male hornbill skulls. Information from Cameroon suggest targeted hunting for hornbills to meet market demand (Francis Guetse pers. com.). Our investigations suggest this international trade has occured since about 15 years with growing volumes. Noteworthy is a recent drop in the volume of Yellow-casqued hornbill skulls which could be speculated to be linked to lack of availability due to locally depleted populations. We are uncertain about volumes in the Asien market but think the frequency in western markets alone are reason for concern.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 25 April 2025. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List category on this page on 25 April 2025, when discussions will re-open.
Many thanks to Simon Brusland for the update on the concerning development of the trade in Ceratogymna skulls. Based on available information, our preliminary proposal for the 2025 Red List would be to adopt the proposed classification outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 4 May 2025, after which the recommended categorisations will be put forward to IUCN.
The final 2025 Red List categories will be published on the BirdLife and IUCN websites in October 2025, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Black-casqued Hornbill is recommended to be listed as Near Threatened, approaching thresholds under Criterion A2cd+3cd+4cd.
