Thanks for the update Steve, of note a few days ago I observed two of the roseates at Nickerson displaying courtship behavior. I tried to get it on video, but they stopped before I could start filming. Maybe some are breeding? Or practice? Also of note, some birders observed last year there was a roseate that bred with a common tern but the nest was unsuccessful. Thoughts anyone? Mike Z.
