摘要

钟摆山雀(Penduline Tit Remiz pendulinus)是一种表现出单代养育的物种。要么雌鸟要么雄鸟在孵化开始前抛弃了卵窝，而且双亲都抛弃了大约30%的卵窝。被遗弃的个体可能会再次筑巢，在繁殖季节有多达六个伴侣。我们描述了在瑞典和波兰的四个雄性和一个雌性钟摆山雀明显改变决定的五个案例。在放弃一窝卵几天后，个体返回巢穴并开始孵化。所有的离合器都成功了。

Male and female Penduline Tit Remiz pendulinus can reverse their desertion decisions

The Penduline Tit Remiz pendulinus is a species that displays uniparental care. Either the female or the male parent abandons the clutch before incubation commences, and both parents desert about 30% of clutches. Deserting individuals may nest again and have up to six partners over a breeding season. We describe five cases of an apparent reversal of the decision to desert by four male and one female Penduline Tit in Sweden and Poland. Several days after abandoning a clutch, the individuals returned to their nests and began incubation. All clutches were successful.
