Hello Mono,
I agree with Tom, what a nice gift.
Yes, I agree with all, that the choosen colours represents rather the available colours and a successful attempt to bring in contrast in this bird.
Is it possible to place a "thumbs up"- button on this picture?
And: an interesting idea, to test the Merlin-App with this picture. Maybe the Cornell-Lab can benefit from this idea? Yes, thats a serious question. Why has the app identified it as a Sooty Tern?
And: thank you Mono for sharing the picture and this unconvential idea with us! Together with all the answers and Toms description of a species new to science. Such a nice and pleasant change. Thanks again for sharing!
