| 中文摘要: |
| 2019和2020年，在广西崇左恩城观察了喀斯特森林一对冠斑犀鸟（Anthracoceros albirostris）的繁殖行为。此对冠斑犀鸟每年4 ~ 7月在石壁上的洞穴里营巢，其孵卵期约为35 d，育雏期约为55 d。每年均有2只幼鸟成功离巢。幼鸟及雌鸟食物以植物性食物为主，雄鸟喂食时缺少明显的高峰。结果表明，冠斑犀鸟在繁殖行为上适应了喀斯特这一特殊生境。 |
| 英文摘要: |
| Oriental Pied Hornbill (Anthracoceros albirostris) has been listed as a critically endangered species in China because of its decreasing population and small range. The breeding ecology of Oriental Pied Hornbill in China is poorly known. We observed the breeding behaviors of a couple of Oriental Pied Hornbill in karst forest, during 2019 and 2020. They built their nest on a steep limestone cliff between April and July. The incubation and nestling period were estimated about 35 and 55 days, respectively. Two nestlings were successfully fledged in each year. Male mainly fed fruits of figs to female and their nestlings. There was no obvious feeding peak by male in day. Our results implied that Oriental Pied Hornbills had adapted the karst habitat in breeding behavior. |
