摘要:

2006年4-9月, 采用彩色标记、无线电遥测和卫星跟踪等方法, 对青海湖四种繁殖水鸟斑头雁 (Anser indicus)、棕头鸥 (Larus brunnicephalus)、渔鸥 (L.ichthyaetus)和鸬鹚 (Phalacrocorax carbo)的活动区域进行了研究。采用“绳套法”捕捉了45只斑头雁, 其中6只于4月安装了无线电发射器, 6只于7月安装了卫星发射器; 采用“拉网法”捕捉了104只棕头鸥, 其中6只于4月安装了无线电发射器; 采用“绳套法”捕捉了51只渔鸥, 其中2只于4月安装了无线电发射器; 采用“扣网法”捕捉了75只鸬鹚, 其中6只于5月和6月安装了无线电发射器, 4只于8月安装了卫星发射器。通过研究, 获得了上述四种繁殖水鸟在青海湖的活动区域, 即: 斑头雁有3个主要的活动区域, 棕头鸥有1个, 渔鸥有4个, 鸬鹚有2个。其中从鸬鹚岛、蛋岛、布哈河口、铁卜恰河口至泉湾区域是上述四种繁殖水鸟共有的活动区域, 该区域也是春秋迁徙季节众多水鸟的重要取食地和停歇地。

Abstract

The movements of four species of breeding waterbirds were studied using color marking, radio-tracking, and satellite-tracking at Qinghai Lake between April and September, 2006. Forty five bar-headed geese (Anser indicus) were captured with foot traps, including six individuals tagged with radio transmitters in April and another six birds with satellite transmitters in July. A total of 104 brown-headed gulls (Larus brunnicephalus) were captured with hand nets, and six of these were radio-tagged in April. Fifty one great black-headed gulls (L. ichthyaetus) were captured with foot traps, including two birds that were radio-tagged in April. Seventy five great cormorants (Phalacrocorax carbo) were captured using the spotlight method, including six birds radio-tagged in May and June, and four individuals tagged with satellite transmitters in August. Data showed three distinct movement routes for the bar-headed goose, one for the brown-headed gull, four for the great black-headed gull, and two for the great cormorant. Furthermore, one of these routes was shared by all four waterbird species—from Luci Island and Egg Island to Quanwan along the shore near the Buhahekou and Tiebuqiahekou. These areas are also important as foraging and resting sites for many other waterbird species during migration periods.
