从春季迁移的时间到达研究了4年的男性斑姬鹬（Ficedula hypoleuca）在西班牙中部。遗传力和重复性分析进行了几个层次的家族相似性和男性年龄，以确定是否到达时间是一致的个人之间的年和亲属之间是相似的。最年长的雄性来得更早。到达时间解释了产卵时间和幼鸟数量的变化。独立的翼长的变化也影响了到达日期，最长的翅膀的男性解决较早。到达时间是不可重复的个人跨年，并没有类似的亲属（父母的儿子，全同胞）。虽然遗传变异可能存在于长途迁徙鸟类的出发日期，早期到达高繁殖成功率的密切联系可能耗尽了遗传变异的到达时间。此外，环境变化可能太大，在没有非常大的样本量的情况下无法检测到达时间的显着遗传性。
The timing of arrival from spring migration was studied in 4 years for male Pied Flycatchers (Ficedula hypoleuca) in central Spain. Heritability and repeatability analyses were performed at several levels of familial resemblance and male age in order to determine whether arrival times are consistent within individuals between years and are similar between relatives. Oldest males arrived earlier. Arrival time explained much of the variation in laying time and number of young fledged. Age-independent variation in wing length also affected arrival date, the males with longest wings settling earlier. Arrival times were not repeatable within individuals across years and were not similar between relatives (parents-sons, full-sibs). Although genetic variation may exist in departure dates of long-distance migrant birds, the close connection of an early arrival to high reproductive success may have depleted genetic variation in arrival time. In addition, environmental variation probably is too high to detect significant heritability in arrival times without very large sample sizes.
