Comparing non-breeding distribution and behavior of red-legged kittiwakes from two geographically distant colonies.

Knowledge of non-breeding distributions is a crucial component to seabird conservation, as conditions during the non-breeding period can play an important role in regulating seabird populations. Specifically, if seabirds from different colonies share the same wintering grounds, conditions in that sh...
