Description: |
Good white head, yellow bill with red mark. Back black down to wings where some molting
coloration could be seen. When it flew
it showed a all white tail with a large black spot near the tip of
the two outer feathers. Legs
pink-gray. Personally I didn\'t think the bird looked big enough for a Great
Black-backed, but it was alone with nothing to compare with. When it flew it then seemed to be a large
enough gull. |
