It is undoubtedly a very beautiful species of bird. Apparently its survival is based on constantly migrating to different areas in search of food sources and better places to reproduce. It is a pity that, like many animals, their lives are harmed by human action, especially by the garbage that often contaminates the beaches and that on many occasions end up being ingested by the birds. Very nice photos and are complemented by excellent information @agmoore. A pleasure to read you again, greetings.
