Effects of hunting camps on breeding grey-necked picathartes Picathartes oreas in south-east Nigeria

Abstract

AbstractThe dependence of forest communities on bushmeat as a source of protein and income is a challenge to wildlife conservation in Sub-Saharan Africa. We investigated the use of caves and overhanging rocks as hunting camps and the consequences for breeding grey-necked picathartes Picathartes oreas in the forests of Cross River in south-east Nigeria. We recorded 84 nesting colonies during guided and random searches. We found 14 (16.7%) breeding sites that had been used as hunting camps, with evidence including fire stands, sleeping spots, cooking utensils and drying racks. Fire stands were the most frequently recorded evidence of camping and were found in 11 of the camps. At the 14 breeding sites only two nesting attempts were made by P. oreas during the survey. Thirty-seven nests (c. 95%) recorded in hunting camps were empty and showed no evidence of ongoing or potential breeding activities, suggesting that the nests may have been abandoned. We attributed the low nesting attempt rate to disturbance caused by hunters, who also affected breeding success through direct removal of eggs and fledglings from nests. We encourage conservation education for the protection of P. oreas and other threatened species in the region and recommend strict enforcement of wildlife laws and disciplinary sanctions. Given the role of the forests of Cross River as a critical habitat for several endemic and threatened species, management efforts targeted at improving the integrity of the forest will benefit grey-necked picathartes and other avian species of conservation concern.
