User blog:Maledict Zashley/What Measure is an Anthropomorphic Character?

This is a question that's been simmering on the back of my mind for a bit, mostly in regards to Finn and the Ducklings.

For an analogy, let's say that there was a daughter of Maximum Ride on this forum(and no, I'm not suggesting that Max Ride is a fairytale; any children of her actually on this forum would merely be parody, but this is the most fitting example I could go for character-wise). She's inherited her mother's wings as well as her internal avian traits, such as lower bone density.

Would she constitute as an anthropomorphic character if her only external bird trait is that of wings, but she also has all of these internal traits?

Would she consitute as an anthropomorphic character if she doesn't have any internal bird traits, and the only external trait of wings?

What if she has no wings, but has very bird-like internal traits?

Or do anthropomorphic characters only count as such if their ears/face display anthro traits?

...Is it the tail that defines them?
