灰雁繁殖期的行为日节律及时间分配

2011年4～6月,采用瞬时扫描法对徐州睢宁金桥禽业发展有限公司2对繁殖良好的灰雁的繁殖行为时间分配和活动节律进行研究,采用非参数检验的Kruskal-Wallis H法分析不同性别灰雁繁殖前中后期行为的性别差异,以及相同性别的灰雁在繁殖的不同时期的行为差异。结果显示：灰雁在采食、理羽、静立、趴卧、孵化等行为上存在着明显的节律性。取食行为多发生在上午和下午的中间时段,孵化多在早晨和傍晚,而中午的大部分时间处于休息状态。孵化期内雌雄个体的行为差异很大,灰雁繁殖时期各种行为所占的比例不仅存在着一定的性别差异,而且同一性别个体在不同的繁殖阶段各种行为所占的比例也有很大变化。

Time Budget and Activity Rhythm of Greylag Goose in Captivity during Breeding Season

We used the instantaneous scan method to study the time budget and activity rhythm during breeding of two pairs of greylag goose in good reproductive condition at Xuzhou Jinqiao Poultry Industry Development Co.from April -June 2011.We used the non - parametric Kruskal - Wallis H test to analyze gender differences of breeding behavior of greylag goose in early, mid and late breeding periods,and behavior difference of the same gender in different breeding periods.There was a clear rhythm of feeding,preening,standing,lying,and hatching.Feeding mostly occurred in mid morning and afternoon,hatching occurred most often during morning and night,and birds rested mostly at mid day.During the incubation period,the behaviors of male and female birds varied greatly.Male and female geese differed in their time budgets for various behaviors.Within the same gender,time budgets for various behaviors also varied during different breeding periods.
