Megjegyzések:	Migration plays a fundamental part in the life of most temperate bird species. The regular,large-scale seasonal movements that characterize temperate migration systems appear tohave originated in parallel with the postglacial northern expansion of tropical species. Migratoriness is also influencedby a number of ecological factors, such as the ability to survive harsh winters. Hence, understandingthe origins and evolution of migration requires integration of the biogeographic history and ecology of birds in aphylogenetic context. We used molecular dating and ancestral state reconstruction to infer the origins and evolutionarychanges in migratory behavior and ancestral area reconstruction to investigate historical patterns of rangeevolution in accipitrid birds of prey (Accipitriformes). Migration evolved multiple times in birds of prey, the earliestof which occurred in true hawks (Accipitrinae), during the middle Miocene period, according to our analyses.In most cases, a tropical ancestral distribution was inferred for the non-migratory ancestors of migratory lineages.Results from directional evolutionary tests indicate that migration evolved in the tropics and then increasedthe rate of colonization of temperate habitats, suggesting that temperate species might be descendants of tropicalones that dispersed into these seasonal habitats. Finally, we found that diet generalization predicts migratorinessin this group.
