Thought this was a Herring Gull but now thinking it might be a GBB Gull - is the completely black bill significant?
Appreciate any help. Thanks
You're not alone.
What doesn't make it any easier, there aren't enough books around dedicated to juveniles, at all stages of growth
Don't take my word for it, but I'm about to throw a red herring in, based on the wing tips, and think possibly lesser black backed....
But that is purely a very wild guess, and hopefully someone will put us both out of our misery.
