It has always amused me that the tourists to the US that I’ve spoken to are often very excited to see raccoons, and disappointed if they don’t see them before they leave.
Some others I’ve noticed on the east coast of the US are blue jays and cardinals. Boy, do people get excited about those if they’ve never seen them before! Very pretty birds of course, just very easy to get used to and see as uninteresting as well.
Squirrels are extremely common in (most of?) the US, even in cities. There’s an albino one that lives in my neighborhood, that one was interesting enough to stop and take a picture of.
