Adult terns will often mob/chase if a youngster (fledgling) is around. We were just on Champlain today and saw a number of terns at non-nesting locations with young and they were acting very aggressive even though the young birds were able to fly. Terns are dispersing now across the northern part of the lake and are congregating at staging areas which is why you may have seen them at Arrowhead. Were there any young birds with the terns you saw (white forehead, strongg dark carpal bar, higher piched vocalizations)?

Hi, Mark - A few weeks ago I saw two common terns on Arrowhead Lake in
Georgia, acting like nesting birds (chasing away the kayak, very noisy, etc.)
although I didn't see a nest.
