This is what I'm saying. Chipmunks are not squirrels. I will do my best on this hill.

It looks like common names like "squirrel" or "chipmunk" that cover many different species are taken more as "squirrel-like animal" and "chipmunk-like animal". They are in the same family (Sciuridae).

Just be more specific and it is happy to count them. For example it counts Townsend's chipmunk, Eastern chipmunk, Siberian chipmunk, Douglas squirrel, Eastern gray squirrel, Western gray squirrel, and Red squirrel all as separate animals.

Similarly, it insisted to me that a pigeon is the same thing as a mourning dove. Not true! But your case is even more egregious.

Well TIL prairie dogs are actually squirrels

There are some weird ones. It knew red-bellied woodpecker but not yellow-bellied woodpecker.
