摘要
2016年5月25日在宁夏回族自治区双猫头湖发现了遗鸥。2016年和2017年,利用无人机监测与定点观察相结合的方法,对遗鸥新的繁殖群、繁殖地进行了考察。计数遗鸥810只,约410个繁殖对。繁殖地为湖上2个岛,植被稀疏。另观察到其他鸟类48种。遗鸥食物来源为数量巨大的摇蚊类和豆娘。此次发现为遗鸥在我国繁殖地的新发现。
Relict gull( Larus relictus) was recorded at Shuangmaotou Lake in Ningxia Hui Autonomous Region( 106°46'13″-106°48'15″E; 37°43'26″-37°44'27″N) on May 25,2016. The new breeding population and breeding sites were investigated using drones combined with fixed-point observation in 2016 and 2017. 810 relict gulls( about 410 breeding pairs) were counted. The breeding sites are two islands on the lake where the vegetation is sparse. Forty-eight other bird species recorded. Large numbers of chironomids and Damselflies provided prey for the breeding relict gulls. This is a new record for relict gull breeding in China.
