Admission records of rescued birds are an important source of information for tracking the prevalence of human-related threats to wildlife. In this study, we used admission records from January 2015 to December 2016 to review the causes for raptor admissions to a raptor rehabilitation centre in Pietermaritzburg, South Africa, and to determine factors that can be used to predict the outcome of rehabilitation. During the study period, 242 raptors were admitted to the centre, representing 33 species. The major causes of admission were collision-related injuries (52%), grounded birds (12%) and orphaned chicks (10%). The most common casualties were spotted eagle-owl Bubo africanus (23%), yellow-billed kite Milvus migrans aegyptius/parasitus (12%), jackal buzzard Buteo rufofuscus (10%) and western barn owl Tyto alba (10%). The rehabilitation centre had a release rate of 48%. Reason for admission was a significant predictor of the outcome of rehabilitation while other variables were not. Raptors with no severe injuries such as orphaned chicks and grounded birds were more likely to have successful rehabilitation treatment than raptors suffering from collision injuries. Wildlife rehabilitators can use the results of the present study to develop triage guidelines for raptors admitted to rehabilitation centres.

猛禽康复中心入院的原因和可用于预测释放可能性的因素

获救鸟类的入场记录是追踪与人类有关的野生动植物威胁发生率的重要信息来源。在这项研究中，我们使用了2015年1月至2016年12月的入院记录，回顾了南非Pietermaritzburg的一个猛禽康复中心猛禽入院的原因，并确定了可以用来预测康复结果的因素。在研究期间，有242只猛禽进入该中心，代表33种。入院的主要原因是与碰撞有关的伤害（52％），地面鸟（12％）和孤儿（10％）。最常见的伤亡斑点鹰猫头鹰雕非洲种（23％），黄嘴风筝鸢属移行aegyptius / parasitus（12％），豺鹫红毛（10％）和西部仓n Tyto alba（10％）。康复中心的释放率为48％。入院的原因是康复结果的重要预测指标，而其他变量则没有。与遭受碰撞伤害的猛禽相比，没有严重受伤的猛禽，例如孤雏鸡和地面小鸟，更有可能获得成功的康复治疗。野生动物康复者可以利用本研究的结果来为康复中心的猛禽制定分流指南。
