摘要
2005年和2006年冬季,利用样方法调查了哈尔滨师范大学江北校区的黑眉苇莺和红尾伯劳2种鸟巢的数量、分布和巢址特征等。结果表明,校园中黑眉苇莺巢的数量较多,主要选择红瑞木作为营巢树种,而红尾伯劳巢的数量较少,主要选择较高乔木营巢,2种鸟巢的数量在2 a间呈减少趋势,且分布区逐渐缩小,建议增加适于其生存和繁殖的生境,提高大学生的保护意识,创建和谐的校园生态文明。
Number, distribution and sites of nests of Acrocephalus bistrigiceps and Lanius cristatus were surveyed in November and December, 2005 and 2006 by the sample quadrat method. Results indicated that nests of A. bistrigiceps were rather numerous and constructed mainly on Comus alha, while those of L, cristatus were less in number and mainly constructed on high trees; in these 2 years, number of nests of these 2 species and areas of＇distribution decreased, so for their protection, improvement of the habitat was recommended.
