“…As such, early shifts of winter ranges may not represent invasions of tropical habitats as much as tracking of tropical habitat to lower latitudes to escape harsh winter conditions while maintaining breeding at high latitudes (36,40). PlioPleistocene glaciations have clearly served to modify geographic ranges and migratory distances and routes (26,41,42) and may have had an influence on more recent shifts of winter ranges out of North America in the Passerellidae (blue branches, Fig. 4).…”

“…Our foci are the major biogeographic events in lineage history that led to the evolution of the Neotropical migratory system, as opposed to the appearance or disappearance of migratory behavior in a population per se. Migratory behavior has been shown to sometimes change very rapidly (46) and is sensitive to temporally ephemeral changes, such as range oscillations during North American glacial cycles (26,41,42). Conversely, domino states are geographically broad and therefore temporally more stable and appropriate for phylogenetic analysis than are finer geographic state delineations that would capture more nuanced, but fleeting, contemporary details of migratory behavior.…”

Migratory species exhibit seasonal variation in their geographic ranges, often inhabiting geographically and ecologically distinct breeding and nonbreeding areas. The complicated geography of seasonal migration has long posed a challenge for inferring the geographic origins of migratory species as well as evolutionary sequences of change in migratory behavior. To address this challenge, we developed a phylogenetic model of the joint evolution of breeding and nonbreeding (winter) ranges and applied it to the inference of biogeographic history in the emberizoid passerine birds. We found that seasonal migration between breeding ranges in North America and winter ranges in the Neotropics evolved primarily via shifts of winter ranges toward the tropics from ancestral ranges in North America. This result contrasts with a dominant paradigm that hypothesized migration evolving out of the tropics via shifts of the breeding ranges. We also show that major lineages of tropical, sedentary emberizoids are derived from northern, migratory ancestors. In these lineages, the winter ranges served as a biogeographic conduit for temperate-to-tropical colonization: winter-range shifts toward the tropics during the evolution of long-distance migration often preceded southward shifts of breeding ranges, the loss of migration, and in situ tropical diversification. Meanwhile, the evolution of long-distance migration enabled the persistence of old lineages in North America. These results illuminate how the evolution of seasonal migration has contributed to greater niche conservatism among tropical members of this diverse avian radiation.evolution of migration | historical biogeography | dispersal-extinction-cladogenesis | bird migration | tropical niche conservatism T he evolution of seasonal migratory behavior among animals involves a suite of behavioral, physiological, morphological, and neurological adaptations that enable migrants' extraordinary feats of endurance and navigation (1-3). However, the evolution of migration also is an inherently geographic process during which a species' breeding range and nonbreeding range (henceforth, winter range) become physically and ecologically separated (4). Understanding the evolution of migration therefore requires reconciling the fascinating adaptations of migratory individuals with the biogeographic factors that control the shifting boundaries of a species' range (5). The field of historical biogeography has shed considerable light on the geographic histories of organisms (6, 7) but has largely ignored migratory species due to the difficulty of simultaneously reconstructing the evolution of the breeding and winter ranges, which in migratory species are often ecologically disparate and separated by long distances (5). Consequently, progress in our understanding of the evolution of migration has been impeded by a biogeographic conundrum: testing hypotheses on the evolution of migration requires knowledge of the geographic histories of migratory species (4,8,9), but the existence of migratory b...

“…After this symposium, our model of migration expanded from one of temperate land birds visiting the tropics to avoid harsh winters, to include birds with an evolutionary origin in the tropics using the temperate zone as a seasonal reproductive strategy. Tropical or subtropical origins for many of these land-bird groups have subsequently been supported by phylogeographic studies (Bohning-Gaese and Oberrath 2003, Steadman 2005, Mila et al 2006, Kondo and Omland 2007, Bruderer and Salewski 2008; but see Zink 2002).…”

Abstract. Migratory bird needs must be met during four phases of the year: breeding season, fall migration, wintering, and spring migration; thus, management may be needed during all four phases. The bulk of research and management has focused on the breeding season, although several issues remain unsettled, including the spatial extent of habitat influences on fitness and the importance of habitat on the breeding grounds used after breeding. Although detailed investigations have shed light on the ecology and population dynamics of a few avian species, knowledge is sketchy for most species. Replication of comprehensive studies is needed for multiple species across a range of areas.Information deficiencies are even greater during the wintering season, when birds require sites that provide security and food resources needed for survival and developing nutrient reserves for spring migration and, possibly, reproduction. Research is needed on many species simply to identify geographic distributions, wintering sites, habitat use, and basic ecology. Studies are complicated, however, by the mobility of birds and by sexual segregation during winter. Stable-isotope methodology has offered an opportunity to identify linkages between breeding and wintering sites, which facilitates understanding the complete annual cycle of birds.The twice-annual migrations are the poorest-understood events in a bird's life. Migration has always been a risky undertaking, with such anthropogenic features as tall buildings, towers, and wind generators adding to the risk. Species such as woodland specialists migrating through eastern North America have numerous options for pausing during migration to replenish nutrients, but some species depend on limited stopover locations. Research needs for migration include identifying pathways and timetables of migration, quality and distribution of habitats, threats posed by towers and other tall structures, and any bottlenecks for migration. Issues such as human population growth, acid deposition, climate change, and exotic diseases are global concerns with uncertain consequences to migratory birds and even lesscertain remedies. Despite enormous gaps in our understanding of these birds, research, much of it occurring in the past 30 years, has provided sufficient information to make intelligent conservation efforts but needs to expand to handle future challenges.

“…when ice-sheets extended towards lower latitudes [25]). Migratory species also had a higher ability to recolonize seasonally highly productive arctic habitats following glacial retreats [26][27][28]. On the other hand, travelling long distances exposes individuals to high levels of stress and increases the risk of mortality [29] as well as demographic fluctuations [30,31], potentially leading to overall higher extinction rates.…”

Settling down of seasonal migrants promotes bird diversification

How seasonal migration originated and impacted diversification in birds remains largely unknown. Although migratory behaviour is likely to affect bird diversification, previous studies have not detected any effect. Here, we infer ancestral migratory behaviour and the effect of seasonal migration on speciation and extinction dynamics using a complete bird tree of life. Our analyses infer that sedentary behaviour is ancestral, and that migratory behaviour evolved independently multiple times during the evolutionary history of birds. Speciation of a sedentary species into two sedentary daughter species is more frequent than speciation of a migratory species into two migratory daughter species. However, migratory species often diversify by generating a sedentary daughter species in addition to the ancestral migratory one. This leads to an overall higher migratory speciation rate. Migratory species also experience lower extinction rates. Hence, although migratory species represent a minority (18.5%) of all extant birds, they have a higher net diversification rate than sedentary species. These results suggest that the evolution of seasonal migration in birds has facilitated diversification through the divergence of migratory subpopulations that become sedentary, and illustrate asymmetrical diversification as a mechanism by which diversification rates are decoupled from species richness.
