Roost site preferences influence the spatial distribution of species. Large soaring birds often roost on cliffs and large structures, and thus are restricted to areas where safe take-offs and landings can occur. The cliff roosting preferences of the Cape Vulture Gyps coprotheres were explored for five juveniles and nine adult birds. Generalised linear mixed models (GLMM) were used to identify which features were considered favourable for cliff roosting sites. Roost density around colonies (breeding colonies for adults and natal colonies for juveniles) was calculated in predetermined buffer sizes and a GLMM was fitted to the data to investigate the effect of distance from colony and age. Both age classes of Cape Vultures showed a cliff roost preference for areas that were located closer to colonies, in protected areas and were of high topographical elevation with a southwest orientation. Cliff roost sites of a south aspect that had predominately east winds were also favoured. The highest density of roosts for juveniles and adults was located within 40 km from the breeding colony. The protection of roosting sites is an important consideration for conservation management particularly given the high concentrations of vulnerable birds.

栖息地的偏好会影响物种的空间分布。大型高飞鸟类通常栖息在悬崖和大型建筑物上，因此仅限于可以安全起飞和降落的区域。Cape Vulture Gyps coprotheres的悬崖栖息地偏好探索了五只幼鸟和九只成年鸟。使用广义线性混合模型（GLMM）来确定哪些特征被认为对悬崖栖息地有利。在预定的缓冲液大小中计算菌落周围的栖息密度（成年繁殖菌落和未成年繁殖菌落），并将GLMM拟合到数据中以研究距菌落距离和年龄的影响。秃age的两个年龄类别都显示出对栖息地较偏僻的地区的偏爱，这些地区更靠近殖民地，保护区，并且地势高，西南偏。偏南主要是东风的悬崖栖息地也受到青睐。幼鸟和成虫的最高栖息地密度位于繁殖种群40公里以内。
