摘要
本文介绍了油毡巢箱制做方法并从大山雀的平均窝卵数及雏鸟存活率等方面,讨论了油毡巢箱招引大山雀的适宜性。不同巢箱密度的实验表明,产卵巢箱分布与巢箱安置方式基本一致,并向均匀分布方向偏离随机分布(R=1.1—1.4)。产卵巢箱密度与巢箱密度之间相关性不显著(r=0.30,P<0.05),巢箱距离以30—50m为宜,巢箱过密不能增加招引鸟的数量。
The experiments of six different densities of artificial asphalt felt nest-boxes areas showed that the distribution patterns of laying nest-boxes of great tit (Parus major) deviated from random expectation in the direction of uniformity (R=1.1 to 1.4), as the same as the distribution patterns of established nest-boxes (R=1.2 to 1.6). The correlation between the densities of laying nest-boxes and the densities of established nest-boxes was not obvious (r=0.30). The suitable distance between established nest-boxes was about 30 to 50 m.
It is easy to make asphalt felt nest-boxes and its cost is lower than that of the wooden nest-boxes The process of making asphalt felt nest-boxes was introduced and its suitabilities for great tits were discussed in the aspects of the average clutch-size and the survival of eggs and nestlings of great tits.
