Hi Foghorn some Common Terns can have all red bills.Arctic terns usually have dark blood red bills and normally shorter in length than Common Terns.As i was saying to you before look at the jizz of the birds ,Arctic tern has a different jizz to Common Tern.Hi Ray,
I commented the following on the TBC website as well:
Image 3 looks like an Arctic Tern to me. I can't see any hint of black on the tip of the bill which rules out Common Tern. Also adult Roseate Terns have quite a large amount of black on the bill, far more black than red on birds I have seen.
Fantastic photos as well by the way.
Hope this helped
