2007~2010年,笔者在河南董寨国家级自然保护区,对灰脸 鹰(Butastur indicus)的繁殖状况进行了调查。结果显示,灰脸 鹰于每年2月底、3月初迁来董寨保护区,营巢于高大乔木上,巢位多接近巢树主干。窝卵数为2~3枚,平均(2.75±0.46)枚(n =8)。在所观察的14个繁殖巢中,有11巢繁殖成功,成功率达78.57%。本调查结果将灰脸 鹰繁殖区的文献记录从黄河以北地区扩展到了河南省的南部。
The breeding biology of the Grey-faced Buzzard (Butastur indicus)was studied from 2007 to 2010 at Dongzhai National Nature Reserve of Henan Province. The results indicated that the Grey-faced Buzzard arrived in the study site at the end of February or the beginning of March. They built the nests on big trees and most nests were built on the branch extremely near the trunk. The clutch size was 2.75±0.46 (Mean±SD)(n =8). Eleven of 14 breeding attempts were succeed, the ratio of succeed was 78.57%. This study made the breeding distribution extend to the south of Henan Province from the area in the north of Yellow River.
