Had the redstarts relied on internal cues alone to schedule their spring departure, they would have all left their winter territories at the same time each year.
如果它们的迁徙日期仅仅是由他们自身内部决定，那么它们每年都会在同一时间离开越冬地区。
"Because American redstarts return to the same site to breed each year, arriving later may make it harder for them remain to remain in synch with their breeding cycle," Studds said.
“因为美洲红尾鸲每年都返回同一地区繁殖后代，所以返回时间推迟会使它们的到达时期与繁殖时期很难保持一致。”Studds说。
To examine this, the Smithsonian scientists focused on American redstarts ( Setophaga ruticilla), a member of the warbler family, at a non-breeding site in Jamaica where they conduct long-term studies.
为了验证这一点，史密森学会的科学家们和牙买加科学家共同实施了一项长期研究&观察美洲红尾鸲在牙买加非繁殖地的生活。
