I prefer your version with green eyes :)

The only reproach I will make is that the greyscale gives a somewhat sad image.

This picture is very nice but it's really a pity that the tree is too centered, it would have been shifted slightly on the right and the photo would have been perfect!

The title and the EXIF was already above the photo :)

It is a silver goeland, Its somewhat severe look is underlined with a red line. It is an area of bare skin called an orbital circle. It is more or less visible depending on the mood of the bird. It’s a way to communicate with fellow humans.
The more angry the goeland is, the more red his "eyes" are!
For food, the chicks tap on the red spot on their parents' beaks. This automatically causes the regurgitation of a fish puree they are fond of!
