Black Skimmer - Martha's Vineyard
Had to dodge security guards ( yes, security guards on the BEACH !) and hike to a remote spot were this cool bird flew back and forth practically begging to have its picture taken.
60D and 100-400mm - 1/1250 f8, 400mm, ISO 320
Beautiful shot IslanderMV. Good timing.
+1...nice job, well worth your effort
