Banded as breeding adult on Appledore Island, May 2010.

On October 10, Phil saw 4K9 loafing at high tide with a mixed flock of gulls. 4K9 was banded in May 2010 and is part of our long-term population studies as well as the Extra Pair Paternity project being conducted by a Cornell undergraduate this year.
