一些鸟类已经提前了春季迁徙的时间，以应对最近的气候变化。在温带地区过冬的欧洲短途移民被认为比在热带地区过冬的长途移民更受欧洲气候变化的影响。然而，我们发现，通距离移民提前在斯堪的纳维亚半岛的春季抵达比短途移民。通过分析一个长期的数据集从南部意大利，我们表明，长途移民也通过地中海地区更早。我们认为，这可能反映了气候驱动的春季迁徙时间的进化变化。
Several bird species have advanced the timing of their spring migration in response to recent climate change. European short-distance migrants, wintering in temperate areas, have been assumed to be more affected by change in the European climate than long-distance migrants wintering in the tropics. However, we show that tong-distance migrants have advanced their spring arrival in Scandinavia more than short-distance migrants. By analyzing a long-term data set from southern Italy, we show that long-distance migrants also pass through the Mediterranean region earlier. We argue that this may reflect a climate-driven evolutionary change in the timing of spring migration.
