本文研究了暗绿绣眼鸟的繁殖生态,得知每年4月20日左右迁来青岛,10月底全部南迁,居留期约195天;该鸟一般活动在阔叶林中,筑巢于榉树、刺槐、雪松、龙柏等树上;一般产卵4枚;亲鸟孵卵10天出雏;育雏11天出飞;并对雏乌的生长发育变化做了详细记述。初迁来时,主食树木花粉、蚜虫和其他昆虫卵。育雏期主要捕鳞翅目幼虫,为尺蠖、蛾类和双翅目的蝇类等,后期多食树木浆果。这对消灭农林害虫和传授花粉及种子传播非常有益。
This paper studied the breeding ecology of the dark green white-eye white-eye bird, and learned that it was relocated to Qingdao around April 20 each year and all moved southward at the end of October for a period of about 195 days. The bird was generally active in broad-leaved forests and nesting in zelkova trees, Robinia pseudoacacia, cedar, Cypress and other trees; the general spawning 4; hatching eggs hatched 10 days; brood 11 days fly; and Chu Wu growth and development made a detailed account. When the early move to the staple, tree pollen, aphids and other insect eggs. In the brooder stage, Lepidoptera larvae are predominantly caught, and flies of the order, moths and dipterous flies, etc., and post-harvest tree berries. This is very useful for the elimination of agroforestry pests and the transmission of pollen and seeds.
