Description: Accelerating environmental change poses an urgent threat to global biodiversity. While we have ample data on species-level responses to global change, our knowledge of the intricate web of biotic interactions that structure ecological communities remains limited. Using birds of North America, I present two case studies on how the community composition and species interactions are affected by global change, especially human-induced land use changes. Then, I introduce a novel pipeline that enables automatic extraction of species interactions data from citizen science platforms using large language models. Together, these studies present a new framework on studying the community-level consequences of global change in birds and beyond.
