We examine the climatic drivers of migration across the roughly 1,300 species of suboscine birds, a group containing many intratropical migrants. Comparative analyses confirm that migratory behavior in temperate-breeding suboscines evolves in association with temperature seasonality. The evolution of migration in the tropics, however, has a more complex association with climatic variables including precipitation and greenness seasonality. Projections under future climates scenarios show that suboscines will experience average lower temperature seasonality, potentially favoring the loss of migration, but higher precipitation seasonality, potentially favoring an increase in short-distance migration. The divergent impacts of climate on the evolution of different migratory strategies highlights the complexity of climate-movement associations and the challenges of projecting responses to climate change.
