从野生动物救援中心获得的数据是了解野生动物种群面临的威胁的有用手段。本研究的目的是调查入院的原因和结果的长耳猫头鹰（Asio otus）在意大利的救援中心住院。从2010年1月至2014年10月，使用网络表格从13个中心收集数据。考虑了以下变量：入院时的估计年龄;入院日期;发现位置的栖息地;入院的主要原因;以及结局。入院的主要原因与人类活动有关，主要包括碰撞创伤和收集未受伤的雏鸟。尽管猫头鹰有夜间活动的习惯和它们的保护地位，但根据欧盟指令2009/147/CE和意大利国家法律，枪伤也是成年动物的入院原因。总死亡率为47.3%。考虑到年龄段，大多数成年动物死亡，而大多数普利幸存下来，后来被释放。碰撞和枪伤都导致成年动物的死亡率较高。我们建议，解剖病理学和毒理学调查死亡的伤亡，沿着释放后监测康复猫头鹰，将有助于更好地了解死亡原因和实施更成功的康复技术。
Data obtained from wildlife rescue centres are a useful means of understanding threats posed to wild animal populations. Aims of the present study were to investigate the causes of admission and outcomes of Long-eared Owls (Asio otus) hospitalised in rescue centres in Italy. Data were collected from 13 centres form January 2010 to October 2014 using a web form. The following variables were considered: estimated age at admission; date of admission; habitat at finding location; main cause of admission; and outcome. Major causes of admissions were related to human activities, mainly consisting of collision trauma and collection of uninjured fledglings. Despite nocturnal habits of owls and their protection status, according to European Union Directive 2009/147/CE and to national Italian laws, gunshot wounds were also represented as an admission cause in adult animals. Overall mortality rate was 47.3%. Considering age classes, the majority of adult animals died while the majority of pulli survived and were later released. Both collisions and gunshot wounds contributed to the higher mortality in adult animals. We suggest that anatomopathological and toxicological investigation of dead casualties, along with post release monitoring of rehabilitated owls, would contribute to a better understanding of mortality causes and to the implementation of more successful rehabilitation techniques.
