【摘要】 2003年10月至2004年4月,在对海南鳽进行驯养的基础上,采用全部事件取样法研究了笼养海南的活动时间分配。结果表明:笼养海南鳽一天中除静栖和静立外,其余各行为所占时间比例在白天极少,而在晨(5∶00~7∶00 am)、昏(19∶00~21∶00 pm)和午夜(23∶00~1∶00 am)较大,呈明显的日活动节律;节律变化与季节有关;海南鳽各种行为活动所占比例依次为静栖82.48%、静立8.64%、运动5.36%、取食1.97%、身体护理1.30%、其它0.25%。其时间分配不受季节(春、秋、冬季)影响。更多还原

【Abstract】 This paper presents some recent results on the time budget of white-eared night heron(Gorsachius magnificus) in captivity,an endangered species in the world.The observation by all-occurrences’ recording method from October 2003 to April 2004 was conducted.The results are as follows: The time that white-eared night heron started to act at dark was changeable in different months.During the observation,the earliest starting time was 17∶07 pm on April 15th and the latest time was 18∶49 pm on February 3th.The major behaviors of the heron were standing,resting,moving,feeding,body caring and others(including excreting,drinking and calling).Daily time budget was: resting 82.48%,standing 8.64%,moving 5.36%,feeding 1.97%,body caring 1.30%,others 0.25%(Fig.3).Most of the time was occupied by resting and standing in a day.There were no significant differences in time budget among seasons.Standing,moving and body caring showed three peaks in a day,i.e.from 6∶30 to 9∶00 am,18∶00 to 21∶00 pm and 23∶00 pm to 1∶00 am.However,the exact time these activities occurred and lasted was different.Standing showed two peaks at night,i.e.from 19∶00 pm to 1∶00 am and 5∶00 am to 7∶00 am.Moving had three peaks which were from 17∶00 to 19∶00 pm,23∶00 to 1∶00 am and 5∶00 to 7∶00 am.Feeding mainly occurred from 19∶00 to 21∶00 pm and then decreased till dusk.Body caring occurred from 19∶00 to 21∶00 pm and 23∶00 to 1∶00 am.Resting was conversed to other activities(Fig.1).It might suggest that daily activities of white-eared night heron always occurred at dark,dusk and midnight. Analysis of variance showed that resting,standing,moving,feeding,body caring in different time of a day were different significantly(F=2.501～11.331,P<0.01,df=107).更多还原
