: So then all of the larger terns at the Marathon Government Center are Roseates? I'm floored. Both Vince McGrath and I saw them last Sunday and would have sworn on a stack of Bibles that there were Forster's there. Guess we have a lot to learn about terns!
Terns are tough! One useful fieldmark is that Forster's are much heavier than Roseates (6 oz. vs. 3.9 oz.). If you size the larger terns there you'll see they are all the same size = all Roseates.
