| 中文摘要: |
| 采用所有事件取样法对上海动物园自由生活的斑嘴鹈鹕(Pelecanus philippensis)繁殖期行为进行了初步研究。结果表明,繁殖期间雄性的活动时间显著高于雌性(P<0.01)。在昼间节律上,斑嘴鹈鹕有3个活动高峰,分别为6:00~7:00时、10:00~11:00时(雄性)或11:00~12:00时(雌性)、14:00~15:00时。取巢材主要由雄性承担,雌性几乎不外出取巢材(取巢材时间仅占0.4%);雌雄共同筑巢,但雌性用于筑巢的时间明显大于雄性(P<0.01)。雌雄配偶通过换孵的方式共同孵卵,白天雌性的孵卵时间显著高于雄性(P<0.01),换孵频次为(1.62±1.08)次/d。繁殖期间斑嘴鹈鹕雌雄个体间存在着明显的分工与合作。 |
| 英文摘要: |
| The breeding behavior of Spot-billed Pelican (Pelecanus philippensis) was recorded by All-occurrence Recording Method in Shanghai Zoo from March 9th to April 7th, 2010. Three activity peaks occur in daylight hour at 6:00-7:00, 10:00-11:00 (male) or 11:00-12:00 (female), 14:00-15:00 respectively.The activity duration of males are significantly more than that of females (P<0.01).Males spend much more time to get nest materials than females (8.90%±5.04% vs. 6.19%±0.40%), while females spend more time to build nest than males (10.09%±4.81% vs.5.92%±2.62%) (P<0.01).Both male and female take turn in hatching eggs with an average exchange hatching frequency of 1.62±1.08 times/day, however, the female takes more time in hatching than the male (P<0.01).The results indicate that male and female cooperate closely in breeding activity. |
