Except for a few studies in the eastern United States, little has been published on hemoparasites in owls. We surveyed the blood parasites of 108 Northern Saw-whet Owls (Aegolius acadicus) and 24 Flammulated Owls (Otus flammeolus) in Idaho during autumn migration in 1999 and 2000. We also surveyed 15 Flammulated Owls (FLOW) during breeding season in Utah from 2000. Leucocytozoon ziemanni, Haemoproteus syrnii, Haemoproteus noctuae, and Trypanosoma avium were identified. The overall prevalence of infection was 53% (78/147) and for the combined species, prevalences of Haemoproteus, Leucocytozoon, and Trypanosoma species were 20%, 39%, and 4%, respectively. Northern Saw-whet Owls (NSWO) had an overall prevalence of 51% (55/108), with prevalences of 6%, 47%, and 4% by hemoparasite genus, respectively. Flammulated Owls had an overall prevalence of 59% (23/39), with prevalences of 56%, 18%, and 5% by genus, respectively. This study provides baseline hematozoa information for two boreal owl species.
除了美国东部的一些研究外,关于猫头鹰血液寄生虫的报道很少。1999年和2000年秋季迁徙期间,我们在爱达荷州对108只北方锯鸮(Aegolius acadicus)和24只火焰色鸮(Otus flammeolus)的血液寄生虫进行了调查。2000年繁殖季节,我们还在犹他州对15只火焰色鸮进行了调查。鉴定出了齐氏白细胞原虫、锡氏血变原虫、夜鹰血变原虫和鸟锥虫。总体感染率为53%(78/147),对于这两个物种的综合感染率,血变原虫、白细胞原虫和锥虫的感染率分别为20%、39%和4%。北方锯鸮的总体感染率为51%(55/108),按血液寄生虫属划分,感染率分别为6%、47%和4%。火焰色鸮的总体感染率为59%(23/39),按属划分,感染率分别为56%、18%和5%。本研究为两种北方猫头鹰提供了血液寄生虫的基线信息。
