【摘要】 2003年3月到7月,采用野外观察法对吉林左家自然保护区次生林中沼泽山雀(Parus palustris)的繁殖生态进行了研究,结果表明:沼泽山雀在该区域为留鸟,营巢期在4月上、中旬,产卵期在4月中、下旬,孵化期为13~14d;孵化率为89.47%;窝卵数为7~10枚,平均8枚(n=5)。雏鸟体质量增长符合Logistic规律,增长率为0.41,渐近线为13.25g。同时,给出了次生林中繁殖的沼泽山雀的主要生长参数曲线及巢位特征。更多还原

【Abstract】 An observation was made on the breeding ecology of Parus palustris brevirostris in the secondary forest in Zuojia Nature Reserve of Jilin Province during the breeding season in 2003. Result shows that the birds are resident in this area. The main growth parameters were obtained as nest building stage during early April and mid-April, laying period between mid-April and late April, incubation period 13～14 days, hatching rate 89.47%, and clutch size from 7 to 10 with an average of 8 (n=5). The growth of nestling’s body weight accords with Logistic equation (the growth rate is 0.41 and the maximum estimation value of body weight for the nestling flew out of the nest is 13.25 g). Moreover, the curves of main growth parameters and the nest-site characteristics were given.更多还原
