Artificial light at night is a top predictor of bird migration stopover density. [PDF]
Nat Commun, 2023 As billions of nocturnal avian migrants traverse North America, twice a year they must contend with landscape changes driven by natural and anthropogenic forces, including the rapid growth of the artificial glow of the night sky.

Global dissemination of influenza A virus is driven by wild bird migration through arctic and subarctic zones. [PDF]
Mol Ecol, 2023 Influenza A viruses (IAV) circulate endemically among many wild aquatic bird populations that seasonally migrate between wintering grounds in southern latitudes to breeding ranges along the perimeter of the circumpolar arctic.

Favorable winds speed up bird migration in spring but not in autumn. [PDF]
Ecol Evol, 2022 Wind has a significant yet complex effect on bird migration speed. With prevailing south wind, overall migration is generally faster in spring than in autumn.

Advancement in long-distance bird migration through individual plasticity in departure. [PDF]
Nat Commun, 2021 Globally, bird migration is occurring earlier in the year, consistent with climate-related changes in breeding resources. Although often attributed to phenotypic plasticity, there is no clear demonstration of long-term population advancement in avian ...

Quantifying year-round nocturnal bird migration with a fluid dynamics model. [PDF]
J R Soc Interface, 2021 To understand the influence of biomass flows on ecosystems, we need to characterize and quantify migrations at various spatial and temporal scales. Representing the movements of migrating birds as a fluid, we applied a flow model to bird density and ...

Macro-scale relationship between body mass and timing of bird migration. [PDF]
Nat CommunClarifying migration timing and its link with underlying drivers is fundamental to understanding the evolution of bird migration. However, previous studies have focused mainly on environmental drivers such as the latitudes of seasonal distributions and ...

Synchrony of Bird Migration with Global Dispersal of Avian Influenza Reveals Exposed Bird Orders. [PDF]
Nat CommunHighly pathogenic avian influenza virus (HPAIV) A H5, particularly clade 2.3.4.4, has caused worldwide outbreaks in domestic poultry, occasional spillover to humans, and increasing deaths of diverse species of wild birds since 2014.

The genetics of bird migration
Current Biology, 2022 Bird migration is one of the most amazing biological phenomena exhibited by organisms today, with birds as small as three grams travelling thousands of kilometers twice each year. Most people are familiar with this behaviour; they likely recognize the seasonal movements of birds each year and may have even witnessed specific migratory events (e.g ...

Simulation-based reconstruction of global bird migration over the past 50,000 years. [PDF]
Nat Commun, 2020 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 ...

Decoupling of bird migration from the changing phenology of spring green-up. [PDF]
Proc Natl Acad Sci U S ASignificance Spring vegetation green-up generates important food resources for many migratory animals, provided the timing of green-up matches the timing of migration.
