摘要
黑颈鹤是世界上唯一生长、繁殖在高原的鹤类,被IUCN列为易危物种。为了研究党河湿地黑颈鹤繁殖的威胁因素,2014年、2015年和2018年在甘肃盐池湾国家级自然保护区的党河湿地布设红外相机,对黑颈鹤的巢址监测与分析。结果表明,家犬、赤狐、金雕、猎隼、大鵟是黑颈鹤孵化期和育雏期的主要威胁,天气因素和人为活动也会对黑颈鹤繁殖造成干扰,人为活动接近黑颈鹤巢穴大约800m时,孵卵的黑颈鹤亲鸟受惊鸣叫离巢。
Grus nigricollis is the only crane in the world that grows and breeds in the plateau, and the bird which is listed as vulnerable species by the IUCN. In order to study the breeding threat factors of Grus nigricollis in the Danghe wetland, inf-rared cameras were set up in danghe wetland in Yanchiwan national nature reserve in Gansu province in 2014, 2015 and 2018 to monitor and analyze the nesting sites of Grus nigricollis. The results show that the Canis lupus familiaris, Vulpes vulpes, Aquila chrysaetos, Falco cherrug, Buteo hemilasiu are the main threats to the incubation period of the Grus nigricollis and brood stage, weather factors and human activities also interfere with the reproduction of the Grus nigricollis, When human activity approaches the nest of Grus nigricollis about 800 m, hatching Grus nigricollis parents are frightened and cry to leave the nest.
