摘要
2006年5月1日~7月18日,对哈尔滨北方森林动物园1对笼养灰鹤繁殖期行为进行观察,研究表明:笼养条件下,灰鹤静立(雄31.08%,雌35.81%)、理羽(雄19.81%,雌12.45%)、采食(雄13.23%,雌15.09%)行为比例较高,而繁殖行为占总行为时间比例雄鹤为2.49%、雌鹤为10.30%。灰鹤各行为日节律不明显;静立、理羽、休息和繁殖行为的发生受天气状况影响显著,尤其是静立和理羽差异极显著。灰鹤雌雄行为差异性在中期较显著,就整个繁殖期看,受天气状况的影响行为差异不显著。
The time budget of behaviors of a pair of the common crane ( Grus grus ) in cage in Harbin Zoo was recorded from late April to late July: standing, male 31.08%, female 35.81%; pluming, male 19.81%, female 12.45%; feeding, male 13.23%, female, 15.09%, all much higber than the time for breeding, male, 2.49%, female, 10.30%.Rhythm in behaviors was not clear, yet affected by weather conditions significantly, especially for standing, pluming and breeding.During egg layering and incubation stages, differences in time budgets for males and females were significant, while differences of influences of weather conditions in the breeding season as a whole were slight.
