Advancement in long-distance bird migration through individual plasticity in departure

Authors: Jesse R. Conklin et al. Year: 2021 Publication: Nature Communications Publication Link: https://doi.org/10.1038/s41467-021-25022-7 Abstract`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
