Thanks for the thorough reply.
Maybe you can just click on some animals you like and see if you can see yourself in the description?
I don't think that really works, because like you said, humans are very good with pattern recognition and will probably see bits and pieces of many of these general descriptive phrases in ourselves.
Lately, I've been feeding 2 crows that live in my neighborhood. I think they are smart and pretty cool, as they can recognize me and knows that I will feed them. They also killed 2 rats for us and would chase away other crows that try to stay in or near our yard. So the amount of bird poop on our cars and around our proerty actually decreased a bit after i started feeding them. I guess our home has become their territory. Anyways, I'm just going to claim that my spirit animal is the crow.
According to the site you shared, crows are intelligent, fearless/audacious, flexible/adaptable, related to magic and mystery of creation. But they have negative qualities like manipulative, mischief, trickster like behavior, cunning, stealing. So basically, if I'm a crow, I get to be Loki.
