Sandwich Terns, four, cruise ship dock, San Juan, Puerto Rico
観察結果の詳細
Smaller terns than nearby Royal Terns. Most of these terns had black caps with a crest at the back of the head that gave the head a more squared appearance than some of the other Gull-billed Terns. The bills were long, thin black with a yellow tip. These terns were in a different group at the end of the dock. There were several pairs that were copulating. (This is the next sighting for me since my first sighting in 1987.)
