Helen has made an initial reply advising that she is extremely busy, but noted that she will get back to me. Thank you, Artie, for noting that the terns observed are possibly Caribbean. That makes sense as a target species on the way back home was Cuban Yellow Warbler at the Card Sound Toll Booth. The biting flies there were relentless, so no warbler seen.

Thanks Bob. I know that Helen would love to receive JPEGs of any banded Roseates. Birds of this species with half red bills in June may be Caribbean birds.
