作者以极大的耐心,仔细观察并记录了一对黑枕黄鹂夫妇从产卵抱窝到幼雏成长直至幼鸟出巢的全过程。虽然得以近距离接触,但如何辨认雌雄鸟?雌鸟孵卵期间如何进食?亲鸟为何吞食雏鸟的粪便?雌雄鸟似乎有不同的喂食偏好,这是普遍规律还是特殊现象呢?诸多问题还有待进一步研究解答。
The author with great patience, carefully observed and recorded a pair of black-framed oriole couples from spawning nest to young chicks grow until the young bird out of the nest of the whole process. Although close contact, how to identify male and female? How does the female feed during hatching? Why does the parent devour the hatchery? Does male and female birds seem to have different feeding preferences? Is this a common law or a special phenomenon? Further study and answer.
