Here are some photos of some terns I saw yesterday at Deerfield Beach Pier. There are 2 that I am pretty sure are Gull billed, 1 (with 4 images that is a Sandwich) and 5 that I am not sure. The bills look too long to me for gull billed and I don't see any yellow for Sandwich (possibly because of the poor photo quality). Thinking they could be Common Tern?
They were too far out for much of a size comparison.
Any insight/opinions would be appreciated.
