摘要

摘要近年来在日本内陆地区发现了海狮鱼鹰(Osprey Pandion haliaetus)，但人们对其饮食尚不清楚。在本研究中，CCD摄像机在2017年繁殖季节对岩手县的鱼鹰两个巢穴进行了监测。这对夫妇(一个在水库附近筑巢，一个在河边筑巢)都吃了引进的鱼类，尤其是大口黑鲈和日本鲫鱼。日本的其他鱼鹰种群也食用类似的猎物，这表明引进的鱼类可能是日本鱼鹰的主要食物来源之一。

Diet of the Osprey Pandion haliaetus in Inland Japan

Abstract The Osprey Pandion haliaetus has recently been found in inland areas of Japan, but its diet there is not well understood. In this study, CCD cameras were used to monitor Osprey two nests in Iwate Prefecture during the 2017 breeding season. Both pairs (one nesting near a reservoir, one by a river) consumed introduced fish species, notably Largemouth Bass and Japanese crucian carp. Similar prey are also consumed by other Osprey populations in Japan, indicating that introduced fish may be among the major food resources of Ospreys throughout Japan.
