Today 10-22 at 3:30 p.m. there was a Common Tern at the Chatfield sandspit (Douglas Co). Larger bill than Arctic, red-orange w/ dark tip on the end. Longer legs than Arctic but still short. Bill and legs appeared as adult breeding, less-extensive dark on cap and visible dark carpal-bar appeared as adult non-breeding. Negligible whether tail was shorter than wingtips, from one angle it was, from another angle not so much.
