Current distribution, breeding population and habitat use of the globally threatened Grey-necked Picathartes Picathartes oreas in south-eastern Nigeria: a call for conservation action

摘要: The Grey-necked Picathartes oreas is a globally threatened bird species in Africa with wild population of less than 10,000 individuals. Nigerian population, which has been poorly studied, restricted to the forest Cross River. This study re-assessed distribution, breeding habitat use and current threats by revisiting 91 sites identified during first only survey 1987. We estimated 164 individuals across 82 sites. Only 72 were found localities where had registered Thirteen (18%) these no longer active showed evidence human disturbance. occurrence Picathartes’ nest was positively predicted higher number emergent trees, larger rocks negatively related disturbance matrices. Similarly, colony sizes associated high canopy cover rock height. Also, p...
