秦岭南坡山地林区暗绿绣眼鸟繁殖生态观察

Observation on Breeding Ecology for Zosterops japonicus in the South Slop of Qinling Mountain Forest Regions

通过对秦岭南坡山地林区4处暗绿绣眼鸟巢穴及其繁殖行为进行长期观察,发现暗绿绣眼鸟的繁殖期一般从3月开始,至7月结束,繁殖高峰期为4要6月;营巢需要8～13d,平均营巢时间为10.3d;一般在营巢后5～6d开始产卵,产卵过程一般需要3～5d,平均产卵天数4d,每窝产卵3～4枚,多为3枚;孵卵一般由雌雄鸟轮流承担,孵化期10～12d,平均孵化天数10.75d;雏鸟10～14d后离巢,平均育雏天数11.5d。

Through the long-time observation of 4 bird nests for Zosterops japonicus which were found in the forest regions of south slop in Qinling Mountain ,it was found the breeding time generally stared in March ,and finished in July ,the breeding peak was from April to June.It was need about 8 to 13 days to build the nest,the average nesting time was about 10.3 days ,This species began to lay eggs usually after building the nest 5 to 6 days ,it was taken 3 to 5 days to lay eggs generally ,the average spawning for g days ,each nest spawned eggs for 3 to 4 ,the more nests was 3.In general, it was incubated by the male and female birds in turns, 10 to 12 days for incubation period, the average incubation days for 10.75 days, and the chicks would leave the nest 10 to 14 days later,the average time was 11.5 days for brood.
