Royal Tern Sterna maxima Charadriiformes; Laridae Click on images for full screen Elegants and Royals can be difficult to distinguish. Elegants have a slightly longer and thinner bill, are generally more gracile in body shape, and have a slightly longer crest. Both are easy to distinguish from the Caspian tern, which has a heavy ruby-red (rather than orange) bill and a somewhat less deeply forked tail. Back to Birds of Orange County, California |
