摘 要:2018年6月,在泰湖国家湿地公园对5只苍鹭幼鸟进行了环志并佩戴GPS/GSM鸟类跟踪器。其中3只苍鹭幼鸟在扩散初期死亡,因此只有2只苍鹭幼鸟成功完成出生扩散。故同年对编号为苍鹭NEFU-03、苍鹭NEFU-04的苍鹭幼鸟不同时间的活动距离、活动面积以及飞行速度、飞行高度、活动区域等进行监测。2只苍鹭扩散初期每天飞出巢外活动,日均活动面积分别为0.06367 km2和0.0599 km2,日均活动距离分别为0.7706 km和0.7987 km;飞行速度分别为38 km/h和12.6 km/h,最大飞行高度分别为224 m和545 m。扩散中期幼鸟离开繁殖地到其它湿地活动,不再归巢,日均活动面积分别为220.6683 km2和9.1174 km2,日均活动距离分别为25.06846 km和12.8771 km;飞行速度分别为50.6 km/h和123 km/h,飞行高度分别达215 m和525 m。扩散后期日均活动面积分别为4.2989 km2和14.2428 km2,日均活动距离分别为9.2322 km和5.744 km;飞行速度分别已达46.7 km/h和51.5 km/h,飞行高度分别为2792 m和303 m。研究结果表明,苍鹭幼鸟的活动面积、活动距离、飞行高度、活动时间均随日龄增长而增长。Five grey heron chicks were ringed by GPS/GSM bird trackers at Taihu National Wetland Park of Heilongjiang Province in June 2018. Three grey heron chicks died at the beginning of the dispersion, so only two grey heron chicks successfully completed the natal dispersion. Therefore, in the same year, the grey heron chicks numbered NEFU-03 and NEFU-04 respectively, were monitored at different times for their activity distance, activity area, flight speed, flight height, range of activity, etc. The two grey heron chicks flied out of the nests during the early dispersion period, and the average activity area per day was 0.06367 km2 and 0.0599 km2 respectively. The average activity distance per day was 0.7706 km and 0.7987 km respectively. The flight speed was 38 km/h and 12.6 km/h respectively, and the maximum flight height was 224m and 545 m respectively. The grey heron chicks left their nests during the medium dispersion period and the average activity area per day was 220.6683 km2 and 9.1174 km2, respectively. The average activity distance per day is 25.06846 km and12.8771 km respectively. The flight speed was 50.6 and 123 m/h, and the maximum flight height was 215 and 525 m. During the late dispersion period, the average activity area per day was 4.2989 km2 and 14.2428 km2, respectively. The average activity distance per day is 9.2322 km and 5.744 km respectively. The flight speed was 46.7 km/h and 51.5 km/h, and the maximum flight height was 46.7 km/h and 51.5 km/h. The result showed that the activity area, activity distance, flight height, and activity time for grey heron chicks increased with the day age.
