Identifying the isolating barriers that lead to species formation is challenging. New genomic, phylogenetic and life-history data in Tyrant flycatchers - the largest bird family - suggest long-distance migration contributes to reproductive isolation among closely related forms and to differential diversification across the family.
确定导致物种形成的隔离屏障具有挑战性。在霸鹟科（最大的鸟类科）中，新的基因组、系统发育和生活史数据表明，长途迁徙有助于密切相关的形式之间的生殖隔离，并导致整个家族的分化程度不同。
