Green H99 was banded as a chick on July 10 2007 on Appledore near the swimming hole. H99 spent much of his or her youth at Jenness Beach in Rye, NH, and was spotted there in July and September of 2008, October of 2009, and August of 2010. H99 returned to Appledore in May of 2012, and is overwintering at Hampton Beach.

Note extensive black in bill, suggesting immaturity (it is known 'pure' adults may develop some black on the bill in winter - and even vestiges of black in breeding plumage-, but quite a lot in this wintering bird).
