To reveal the dietary ecology of the peregrine falcon (Falco peregrinus), we conducted a molecular analysis for mitochondrial genes (COI and CYTB) to identify the prey species collected from a feeding place found on Sasu Island, South Korea. The results from noninvasive genetic analysis showed that the sequences obtained came from nine species of birds (Cuculus canorus, Eurystomus orientalis, Limosa limosa, Microscelis amaurotis, Oriolus chinensis, Phasianus colchicus, Sterna hirundo, Streptopelia orientalis, and Turdus pallidus). Five of the species (C. canorus, M. amaurotis, S. hirundo, S. orientalis, and T. pallidus) had previously been observed on this island, but the other four species (E. orientalis, L. limosa, O. chinensis, and P. colchicus) were newly identified as present. No mtDNA sequences of land animals such as amphibians, reptiles, and mammals were found in the dietary remains, suggesting that the peregrine falcon preys mostly on other birds rather than on other animals inhabiting Sasu Island. This island has rich avian diversity and abundant animal populations and therefore supplies sufficient dietary resources for the peregrine falcon. Our findings suggested that a DNA-based molecular method may be useful to identify the prey species of these birds and may be valuable in future studies of the Endangered peregrine falcon.
为揭示矛隼（Falco peregrinus）的食性生态，我们对线粒体基因（COI和CYTB）进行了分子分析，以鉴定从韩国萨苏岛一个觅食地收集到的猎物种类。非侵入性遗传分析结果表明，获得的序列来自九种鸟类（大杜鹃、黑耳鸢、斑尾塍鹬、黑翅鸢、黑枕黄鹂、雉鸡、普通燕鸥、东方环颈鸻和白眉歌鸫）。其中五种鸟类（大杜鹃、黑翅鸢、普通燕鸥、东方环颈鸻和白眉歌鸫）此前在该岛上已被观察到，但其他四种鸟类（黑耳鸢、斑尾塍鹬、黑枕黄鹂和雉鸡）是新发现的。在食骸中未发现两栖动物、爬行动物和哺乳动物等陆地动物的线粒体DNA序列，这表明矛隼主要捕食其他鸟类，而非栖息在萨苏岛的其他动物。该岛拥有丰富的鸟类多样性和大量动物种群，因此为矛隼提供了充足的食物资源。我们的研究结果表明，基于DNA的分子方法可能有助于识别这些鸟类的猎物种类，并且在未来对濒危矛隼的研究中可能具有重要价值。
