摘要:

2016年冬季在中国云南大理洱海湖滨带采用瞬时扫描法观察骨顶鸡(Fulica atra)越冬行为的昼间时间分配和活动节
律。177次扫描结果表明,在时间分配上,取食是骨顶鸡在洱海越冬最主要的行为,占(63±19)%;其次是休息,占(14±17)%;游
泳占(11±11)%,理羽占(9±9)%,警戒和其他行为占比很小。在取食行为上,洱海中的骨顶鸡以表面进食为主,占取食行为总
时间的(79±11)%。在日间行为节律上,本研究中骨顶鸡具有一天两次的休息高峰期,即中午和黄昏时分。

Abstract:

A transient scanning method was used to observe the time distribution and activity rhythm of wintering behavior of the
Common Coot(Fulica atra)in 2016 at Erhai Lake, Yunnan. The data of 177 times scanning showed that the most important behavior
in winter for Common Coot was feeding, which accounted for(63±19)% of daylight hours. The second important behavior was resting,
which accounted for(14±17)% of daylight hours. Swimming accounted for(11±11)%,preening accounted for(9±9)%,alerting and
others type of behavior accounted for very few of daylight hours. Surface feeding was the main foraging strategy for the Common Coot in
Erhai Lake, accounting for(79±11)% of time spent feeding during daylight hours. The Common Coot in Erhai Lake exhibited two
resting peaks in daytime activity, namely at noon and dusk.

Key words: Common Coot, wintering behavior, time distribution, activity rhythm, Erhai Lake
