小笠原群岛是位于太平洋西北部的海洋岛屿，位于日本本州岛以南1000公里处。在1830年人类殖民之前，这些岛屿缺乏陆生食肉哺乳动物。早期的移民把家猫——费利斯·奥恩斯——引入了岛上，其中一些是从岛上的居民区逃出来的。甚至在1877年，就已经有报道称岛上有许多野猫（Obana 1877）。众所周知，猫的捕食会影响世界各地许多岛屿上的本地鸟类种群，例如东大西洋的新西兰近海岛屿和加那利群岛（Fitzgerald & Veitch 1985, Nogales et al. 1992, Powlesland et al. 1995）。在小笠原群岛，许多研究也强调了猫捕食对本地鸟类的影响（如东京地区森林办事处1994年，东京地区森林办事处1996年，川上2000年）。Ya-mashita（1934）认为，小笠原群岛特有鸟类（如小笠原群岛ThrushTardus rerresriss和小笠原群岛GrosbeakChaunoprocrus ferreorostris）的灭绝部分是由于野猫的增加造成的。但是，没有对野猫的饮食进行详细的研究。猫对小鸟的捕食被认为被低估了，因为这样的猎物被猫整个吃掉，捕食后很少留下可见的遗骸（Kawakami 2000）。转载自Kawakami K， Higuchi H (2002) Ornithological Science 1:143-144，经日本鸟类学会许可。
The Bonin Islands are oceanic islands situated in the northwest Pacific Ocean 1,000 km south of the Japanese main island of Honshu. These islands lacked terrestrial mammalian carnivores until human colonization in 1830. Early immigrants introduced domestic catsFelis earnsto the islands, some of which escaped from the island's residential area. Even by 1877 there were already reports of there being many feral cats on the island (Obana 1877). Cat predation is known to impact native bird populations on various islands around the world, such as the offshore islands of New Zealand and the Canary Islands in the eastern Atlantic Ocean (Fitzgerald & Veitch 1985, Nogales et al. 1992, Powlesland et al. 1995). In the Bonin Islands also, many studies have highlighted the impact of cat predation on native birds (e.g. Tokyo Regional Forest Office 1994, Tokyo Regional Forest Office 1996, Kawakami 2000). Ya-mashita (1934) supposed that the extinction of endemic birds (such as the Ogasawara Islands ThrushTardus rerresrrisand the Ogasawara Islands GrosbeakChaunoprocrus ferreorostris) in the Bonin Islands was partly caused by predation of increased feral cats. But, no detailed study has been conducted on the diet of feral cats. Cat predation on small birds is considered to be underestimated, because such prey are eaten whole by cats and few visible remains are left after predation (Kawakami 2000).Reprinted from Kawakami K, Higuchi H (2002) Ornithological Science 1:143-144, with permission of The Ornithological Society of Japan.
