Migratory mixing of Gallinago delicata (Wilson's Snipe) in wintering areas highlights the need for international coordination for monitoring and management.

This article focuses on the migratory connectivity (MC) of Gallinago delicata (Wilson's Snipe), a widely hunted North American shorebird, by analyzing stable hydrogen isotopes in feathers from 323 individuals harvested in Florida during the nonbreeding season. The study reveals extensive migratory mixing, with breeding origins spanning from Alaska and western Canada to southeastern Canada and the northeastern United States, and minimum migration distances ranging from 1,060 to 4,270 km. Findings indicate low migratory connectivity, meaning individuals from diverse breeding populations converge in shared nonbreeding habitats, complicating local harvest management and conservation efforts. The authors emphasize the need for coordinated, range-wide monitoring and research across breeding and nonbreeding areas to better understand population trends and support sustainable management of this long-distance migrant species.
