Arctic-breeding shorebirds are declining, and predation is a leading cause of nest predation. Some scientists argue that predation is increasing due to climate change, but others assert that increased human disturbance as a result of intensive nest monitoring is alterting predators to nest sites. To better understand this issue, we attached GPS tags to dunlin during the pre-breeding season, and used location data (downloaded remotely) to estimate nest success. Paired with estimated nest success from nearby long-term monitoring plots, we aim to understand nest survival in the absence of human disturbance. We are also investigating how environmental conditions influence adult behaviors and reproductive success.
