We report the causes of morbidity of 2,458 free-living raptors admitted to the Tafira Wildlife Rehabilitation Center on Gran Canaria Island, Spain, during 2003-13. The seasonal cumulative incidences were investigated while considering estimates of the wild populations in the region. These methods were used as a more accurate approach to assess the potential ecologic impact of different causes of morbidity. The most frequently admitted species were the Eurasian Kestrel ( Falco tinnunculus ; 53.0%), the Eurasian Long-eared Owl ( Asio otus canariensis; 28.1%), the Canary Islands Common Buzzard ( Buteo buteo insularum; 8.0%), and the Eurasian Barn Owl ( Tyto alba ; 4.4%). The most frequent causes of admission were trauma (33.8%), orphaned-young birds (21.7%), unknown (18.4%), and metabolic/nutritional disease (11.1%). Local morbidity caused by glue trapping and entanglement in burr bristlegrass (Setaria adhaerens) had prevalences of 5.0% and 1.8%, respectively. The highest number of admissions during the breeding and nonbreeding seasons was observed for the Eurasian Barn Owl and the Barbary Falcon ( Falco pelegrinoides ), respectively, mainly due to trauma of unknown origin.
我们报告了2003年至2013年期间，被送往西班牙大加那利岛塔菲拉野生动物康复中心的2458只自由生活猛禽的发病原因。在考虑该地区野生种群估计数的同时，对季节性累积发病率进行了调查。这些方法被用作评估不同发病原因潜在生态影响的更准确方法。最常被收治的物种是欧亚红隼（Falco tinnunculus；53.0%）、欧亚长耳鸮（Asio otus canariensis；28.1%）、加那利群岛普通鵟（Buteo buteo insularum；8.0%）和仓鸮（Tyto alba；4.4%）。最常见的收治原因是外伤（33.8%）、雏鸟孤儿（21.7%）、不明原因（18.4%）和代谢/营养疾病（11.1%）。胶水诱捕和刺毛刺草（Setaria adhaerens）缠绕导致的局部发病患病率分别为5.0%和1.8%。繁殖季节和非繁殖季节收治数量最多的分别是仓鸮和拟游隼（Falco pelegrinoides），主要原因是不明来源的外伤。
