Winter philopatry in migratory waterfowl
TL;DR: The authors' analyses indicate that geese, swans, and sea ducks show high levels of winter philopatry, with homing rates varying between 49 and 98% to small study areas, and that both genetic and ecological mechanisms may play a role in the evolution of philipatry to the wintering ground.
The Importance of Understanding Migratory Connectivity and Seasonal Interactions
TL;DR: It is clear that a better understanding of migratory connectivity is needed before the authors can understand the forces that have shaped and continue to shape the lives ofigratory birds.

TL;DR: The authors used satellite transmitters to track the 2000–2003 spring migrations of adult female Northern Pintails from California's Central Valley, USA, and found that PTT-tagged Pintail departed during late February to mid-March, and 77%–87% stopped first in the region of south-central Oregon, extreme northwestern Nevada, and northeastern California (SONEC).
