"the mystery gull/ European Herring Gull"

 Back in March 2, 2022 I saw a few gull at Old Field Point Lighthouse that caused a stir - around the same time there was a Glaucous Gull, Iceland Gull (did not see), and an odd/ mystery gull that no one could ID.  I got photos of it and photos of the gull were posted by me and other birders on different forums such as North American Gulls and Whats This Bird on FB.  It seemed that no one was willing to definitively ID the gull and put their name on the line in case they mis-identified it.  Now, the gull has returned to Old Point recently and one birder who got excellent photos of it is sure that it is indeed a European Gull after examining all the feathers etc (something beyond my expertise since I don't know feather names.)  The rest of the local birders are agreeing with that ID so I will also.  This will be my "first" life bird for 2025 even though I saw it years ago.  In the meantime, there was another gull I saw that had lighter wings and lighter yellow legs.  I can't help but think it could be a Yellow Legged Gull since they both have the same "ugly mustard" yellow looking legs.  At the time, it was dismissed as an "odd" gull of a common local type, but when I have the chance I might go looking on my older SD camera cards and see if I have any more photos of it and also of this likely European Herring Gull.  I should point out that since 2022, herring gulls were one species/ 2 subspecies but have now been separated into 2 species - Atlantic and European.
