摘要
2000-2004年秋在辽宁旅顺老铁山自然保护区，通过鸟类环志和直接观察的方法，对该地区雀形目（Passeriformes）鸟类秋季迁徙规律进行了研究。5年共环志11040只雀形目鸟类，发现8种保护区新记录种。结果表明，鸟类迁徙高峰大都集中在10月中下旬；气候条件与鸟类迁徙关系密切；不同年份优势种及种群数量均不同；鸟类的迁徙具有一定的顺序性和集群现象，但不同种类迁徙的种群大小又有差别；2004年雀形目鸟类的种类和数量都明显少于前4年，略有下降趋势。
Migration of passerine birds was studied based on the data of direct observation and bird banding during autumn of 2000 to 2004 in the Laotieshan Mountain Reserve, Liaoning Province. Total of 11 040 birds were banded, among them 8 species were recorded first time in the study area. The migration peak appeared in the middle and later October. Daily minimum temperature and wind condition were closely related to species and amount of the birds passing through the study area. The species dominated and amount of migration birds varied each year. During the five year, insectivorous bird came earlier than granivoreus. The birds migrated in group and the size of group varied with species. The number of species and amount of migration birds was least in 2004 during the study period.
