Many species migrate long distances annually between their breeding and wintering areas1. While global change affects both ranges, impact assessments have generally focused on breeding ranges and ignore how environmental changes influence migrants across geographic regions and the annual cycle2,3. Using range maps and species distribution models, we quantified the risk of summer and winter range loss and migration distance increase from future climate and land cover changes on long-distance migratory birds of the Holarctic (n=715). Risk estimates are largely independent of each other and magnitudes vary geographically. If seasonal range losses and increased migration distances are not considered, we strongly underestimate the number of threatened species by 18-49% and the overall magnitude of risk for 17-50% species. Many of the analysed species facing multiple global change risks are not listed by IUCN as threatened or near threatened. Neglecting seasonal migration in impact assessments could thus seriously misguide species' conservation.
