***mega; arrived at about 16:42; some photos by me may be identifable and others (including Scott Surner) were shooting too; fully expected in this Tropical Storm, and by this time we had heard about Sooty Terns all around us: Boston, Long Island Sound, Manhattan, Pennsylvania, Maryland, etc. This bird flew by close (0.5 mi away or so), and generated some chatter as I screamed ADULT SOOTY TERN! A few people were struggling to get on it, but ultimately all present (10+ people) had prolonged views as this bird worked its way to the east side of the dam, fed in the small cove for 5-10 minutes, and then circled high and flew out over the dam and away (into the wind) to the south. DESCRIPTION: Moderately large tern, larger than a Common Tern with a broad-winged appearance but sharply pointed wingtips. It soared several times for 10-20 seconds and when feeding would swoop down to the water and pick things from the surface much like a Black Tern might. No molting flight feathers or aps in the plumage, so otherwise very crisp looking.Underparts pure white. Underwings white with extensively dark undersides to primaries and secondaries, giving distinct two-toned appearance (like Swainson's Hawk). White underparts sharply demarcated from dark upperparts. Upperparts blackish with a faint hint of brownish on the central back indicating wear. Dark cap and nape connected to back without any sign of a collar, eliminating Bridled Tern. No contrast between black cap and blackish back. White forehead large and prominent in from of eyes and suqared off at rear, not coming to a point over the eye as on Bridled Tern. Tail, when flared and seen from above, had only a single narrow white rectrix, also eliminating Bridled Tern which has 2-3. Tail came to a moderate fork, with a rounded central notch. State bird for me!
