I’ve got a couple places in La Jolla that I go to to photograph animals or seabirds. Lately, one of those spots has had many Royal Terns (Sterna maxima). These images illustrate both non-breeding plumage (which is distinguished by the tern’s black head cap only covering the back of the head) and breeding plumage with a black cap covering the entire top of the head. Cheers, and thanks for looking!
