Abstract
Migration is a widespread response of birds to seasonally varying climates. As seasonality is particularly pronounced during interglacial periods, this raises the question of the significance of bird migration during past periods with different patterns of seasonality. Here, we apply a mechanistic model to climate reconstructions to simulate the past 50,000 years of bird migration worldwide, a period encompassing the transition between the last glacial period and the current interglacial. Our results indicate that bird migration was also a prevalent phenomenon during the last ice age, almost as much as today, suggesting that it has been continually important throughout the glacial cycles of recent Earth history. We find however regional variations, with increasing migratory activity in the Americas, which is not mirrored in the Old World. These results highlight the strong flexibility of the global bird migration system and offer a baseline in the context of on-going anthropogenic climate change.

| Additional Information: | Correction to: Nature Communications https://doi.org/10.1038/s41467-020-14589-2, published online 18 February 2020. The original version of this Article contained an error in the legend of Fig. 2 and Supplementary Figs. 2 and 8–16, each of which incorrectly stated ‘The global patterns were computed as the predicted richness in the past, i.e. predicted number of species per hexagon: 10,000 years before present (a, b); 20,000 BP (c, d); and 50,000 BP (e, f), minus the predicted richness in the present. BP before present. Red areas had more species than today, blue areas fewer’. The correct version reads ‘The global patterns were computed as the predicted richness in the present minus the predicted richness in the past, i.e. predicted number of species per hexagon: 10,000 years before present (a, b); 20,000 BP (c, d); and 50,000 BP (e, f). BP before present. Red areas had fewer species in the past than today, blue areas more’. This has been corrected in the PDF and HTML versions of the Article, and the HTML has been updated to include a corrected version of the Supplementary Information.
