I wonder
Well, there aren’t any actual “seagulls”. There are different types of gulls. And some seem more intelligent than others.
Are you telling me if I live by the sea, these gulls I see are not seagulls?

Technically, correct. They are different types of gulls.

Most popular type is the: Herring Gull.

Sometimes they live in bays, then they’re called bagels.
Yum! I can haz strawberry cream cheese bay gulls?
We have seagulls in my inland city, they breed on an island in our lake. I think the name for our seagulls are silver gulls, famous from the film finding Nemo
