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.

Estimation of fishing and natural mortality when a tagging study is combined with a creel survey or port sampling
TL;DR: This paper shows how to use a creel surveyor port sample to estimate reporting rate as an alternative to use of reward tags and discusses the important implications of this approach which allows separate estimation of fishing and natural mortality rates.
