In many avian species, breeding site fidelity has been more thoroughly investigated than winter site fidelity, yet the latter may have a greater impact on species survivorship. The Common Loon (Gavia immer) is an example of a species whose breeding site fidelity has been well established, but whether it exhibits winter site fidelity remains unknown. Because loons primarily winter in marine waters off coastal shores, winter site fidelity has been challenging to document. We investigated winter site fidelity in Common Loons across North America using satellite transmitters, recaptures, and resightings of previously color-marked individuals. Adult color-marked loons returned in consecutive years to the same wintering coastal locations of California, Washington, Louisiana, Maryland, and Massachusetts. We estimate adult annual survival as 81% and adult winter site fidelity as 87%. This finding has important conservation implications in the aftermath of recent marine oil spills; if loons return to the same contaminated wintering areas annually, decreased fitness and survivorship could result in population level impacts.
