观察细节
Bird seen at 20:40 and stayed around for a few minutes, often approaching the vessel calling. Black Bill and dark shoulder patches fit Common rather than Arctic. The call was very different from South American Tern which i see and hear often throughout the Summer. Having listened to the calls of both species on the internet and getting confirmation from more experienced birders of Common Tern I am 100% happy with the ID. I have previously seen many Common and Arctic Terns in the Northern Hemisphere but not in this plumage state. There has been 2 previous records but I suspect that it would be a species that is under recorded due to observer coverage.
