Oiled King Eider survives 24 years after being cleaned

A recent ringed bird recovery shows something truly remarkable: the oldest known wild King Eider – was a 24-year-old oil spill survivor cared for by International Bird Rescue. This finding proves once again that rehabilitated, formerly-oiled birds can survive many years after treatment and release back to the wild.

The latest discovery involves a male King Eider that was oiled as an adult during an oil spill in Alaska in 1996. The recovered bird survived 23 years after oiling and release, and according to federal banding information, this may well be the oldest known wild King Eider.

According to the Cornell Lab of Ornithology and U.S. Geological Survey (USGS) Bird Banding Lab, which administers the scientific banding or ringing of wild birds in the U.S., the previously oldest recorded King Eider was an unoiled female that was at least 22 years 1 month old when she was recaptured and re-released during banding operations in Nunavut, Canada.
