昆明翠湖越冬红嘴鸥行为谱及PAE编码系统

Ethogram and PAE Behavior Coding System of Wintering Black-headed Gull in Cuihu Park of Kunming

采用定点观察、影像调查、追踪观察、瞬时扫描等方法对云南省昆明市翠湖公园内越冬红嘴鸥的日间行为进行调查研究,归纳并建立了红嘴鸥日间行为谱及其PAE编码系统。共记录到红嘴鸥9大类44种行为,类别包括非飞行类运动、迁飞、觅食、通讯、集群、清洁、停歇、竞争对抗、避害。结合人为干扰及斑块化生境中红嘴鸥的行为,在其行为生态及行为功能基础上进行分类。结果表明,人为因素是影响红嘴鸥在翠湖越冬期间行为的主要因素。

The daytime behavior of wintering black-headed gull( Larus ridibundus ) was researched in Cuihu Park of Kunming by means of fixed-point observation,image investigation,tracking observation and instantaneous scanning.The ethogram and PAE coding system of black-headed gull were summarized and established.This research recorded 44 behaviors belonging to 9 major groups of no-flying activities,flight,foraging,communication,grouping behavior,cleaning,resting,competition and escape.The relative frequency of each behavior in different ecological functions was analyzed based on the human disturbance and fragmented habitat.The results showed that human disturbance was the the main factor affecting the behavior of wintering black-headed gull in Cuihu Park.
