The degradation of critical wintering and migratory stop-over sites is known to have direct consequences on the survival and reproductive condition of migratory shorebirds. However, little is known about migratory movements and connectivity of shorebird populations. By identifying migratory stop-over and wintering areas, we can begin to identify sites that should be conserved and evaluate the relative risks of development and climate change scenarios. From 2021 to 2023, we equipped Buff-breasted Sandpipers in the central coast of Texas in the United States, the Colombian Llanos, and northeast of Cambridge Bay in Canada with GPS tracking devices. The principal objectives of this study were to investigate short-term movements and habitat use during stopover on the Texas coast, as well as secondarily, during stopover in the Llanos region of South America, and Victoria Island in Canada.
