"either or" "not both"

Stmt: Either A or B is in the forest

Question: Is "either or" and "exclusive or" here ?

My Answer:
No, because atleast 1 has to be there but not both.

A B not both
0 0 0
0 1 1
1 0 1
1 1 0

My Discussion:
"Either or" is different than "not both" because "not both" truth table is below.

A B not both
0 0 1
0 1 1
1 0 1
1 1 0

Notice the 1st line is different in both truth tables.

Question for you guys:
please see if my logic is correct

    For logic games, yes, you want to assume an inclusive "or" if it doesn't say "not both." But I think they usually write something like, "at least one of X or Y has to be . . . " to avoid that confusion?

    But make sure you check this out if you haven't already, because more broadly, I think this is the right way to interpret "either A or B" in the English language: https://7sage.com/lesson/clarification-for-either-or/
