I’ve done these ID quizzes in the past and have had several people ask for some more. Gulls are a extremely difficult bird to ID as the same gull can go thru up to 4 different molt patterns and look like a different bird in all of them. Gulls also have a a high occurrence of cross breeding between species and don’t always hybridize when they do leading to multiple generations of crossbred birds which can be very challenging.
I will put up 5 gulls and give the answers and give a day for guesses unless someone gets them right.

That's a sea gull

Want to see someone lose their mind, my ornithology professor would if someone called them that. You didn’t even have to be taking his class, he would go out of his way to lecture random people who said that horrible word. LOL

.....can picture little Johnny saying that to his teacher

Sea Gull too

Herring gull

California gull.

Not supposed to shoot them, but sometimes an individual one just has to go.

Friend of mine feeds them hotdogs soaked in alcohol.

now do I have to look in my Gulls of the World since Ido not know where you have traveled Tray

Garbage geese, every one of them.



Owl

Yes!!!

I've heard of people throwing out alka seltzer?

Nope, gulls are from North American, more precisely SD and AK.
I will admit that location does play a big part of the ID.


And you have all but 1 ID’d correctly.

That's why always like the 007 licence the museum had for ID.

photo 1 with the black tip bill is the only red herring, the pink legs and yellow lours

photo 3 the red herring is the grey legs, everything else lines up; dark iris, light ring on bill,grey wings- grey primaries, some flakes

Alaska can have some European gulls especially when the Arctic ocean has been ice free for several years, and several South American gulls migrate north in their winter

Gone for the day so don't put up a spoiler till late this evening
