A Great Black-Backed Gull (Larus marinus) known as 2E2, seen at Sandy Point State Reservation in Massachusetts on April 1, 2014.
According to The Gulls of Appledore:
2E2 is a male that was banded as an adult on Appledore Island on May 26, 2006. Since then, he has been seen 22 times – but only in 2 distinct places! In the month of May, 2E2 is observed on Appledore (he was observed in 2006, 2007, 2010, 2011 and 2012) but he spends the rest of his year on Plum Island in Newburyport. He has been spotted on Plum Island numerous times in late summer, fall, and winter every year since his banding in 2006 (except in 2008). He has been seen eating Skates, clams, and fish.
Male Great Black-backed Gulls (and Herring Gulls) tend to return to their nesting sites each breeding season (from late April to June), and 2E2 has shown strong fidelity to both nesting and overwintering sites. We know that he has returned to Appledore at least 5 out of the past 7 years.
Researchers estimate that 2E2 is at least 13 years old.
