三门峡市黄河公园大天鹅日间越冬行为研究

Diurnal Behavior of the Cygnus Cygnus Wintering in Yellow River Park of Sanmenxia

2017年11月-2018年1月,采用瞬时扫描法在三门峡市黄河公园进行大天鹅日间行为观察。结果表明:在大天鹅越冬期所有行为中,越冬前期(11月)大天鹅行为以觅食和游动为主,分别占25.34%和23.07%,其次是警觉,占19.65%;越冬前期(12月)大天鹅行为以警觉和睡眠为主,分别占26.36%和26.06%,其次是游动,占19.22%;越冬中期大天鹅行为以游动为主,占37.85%,其次是睡眠,占24.72%。通过斯皮尔曼相关性分析发现,大天鹅的游动、争斗、警觉、飞行与游客人数呈显著正相关,睡眠与游客人数和人类干扰因素呈显著负相关。

From November 2017 to January 2018, researchers conducted a study on the daytime behavior of Cygnus cygnus in Yellow River park of Sanmenxia using the instantaneous scanning method. The results showed that: the major behaviors of Cygnus cygnus were foraging, swimming and alertness, which accounted for 25.34%, 23.07% and 19.65% of the total behavior respectively, at the beginning of the early wintering period (November);the major behaviors of Cygnus cygnus were alertness, sleeping and swimming, which accounted for 26.36%, 26.06% and 19.22% of the total behavior, respectively, at the ending of the early wintering period (December);The major behaviors of Cygnus cygnus were swimming and sleeping, which accounted for 37.85% and 24.72% of the total behavior respectively, in the middle of winter (January). The proportion of behaviors such as walking, flying, and fighting in various periods of the Cygnus cygnus was small, and the time taken on the preening has not changed much. Through Spearman's correlation analysis, it was found that swimming, fighting, alertness and flight of the Cygnus cygnus were significantly positively correlated with the number of tourists. There was a significant negative correlation between sleeping and the number of tourists and human disturbance factors.
