2018年5月23日 · According to a new study, Ghana is losing hornbill species to “uncontrolled” hunting, mostly for meat, from its forested parks and reserves. The researchers found that the five largest species of hornbills in the Bia Biosphere Reserve, a UNESCO World Heritage Site, have disappeared in recent decades.

2018年5月28日 · Six out of eight Ghanaian forest hornbill species have shown significant population declines due to uncontrolled hunting, according to a long-term research project. The large forest hornbills of west Africa are now popular targets of the rampant bushmeat industry now that most mammal species have been all but wiped out in certain areas.

Species with restricted habitat requirements and slow reproductive rates, such as the spectacular hornbills (Bucerotidae) of the Paleotropics, are particularly vulnerable. We present the first long-term quantitative population assessment of nine forest hornbill species in Ghana, part of the Upper Guinea forest biodiversity hotspot in West Africa.

All of the five large frugivorous hornbills of Ghana have disappeared from Bia, four of them since the 1990s ( Bycanistes cylindricus and B. fistulator, Ceratogymna elata and C. atrata ) and one from even earlier ( B. subcylindricus ).

The brown-cheeked hornbill (Bycanistes cylindricus) is a species of hornbill in the family Bucerotidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, and Togo. Its natural habitats are tropical and subtropical moist broadleaf forests, plantations, and …
