I'd like to create an agent noun from the verb volo (volare), meaning "one who flies". For some additional context, this will be used as a name for an animal that flies but has characteristics that make it noteworthy that it flies. In other words, by calling the thing a "flyer" it is highlighting that skill in particular (as opposed to something like avis where flying is inherent to the animal).
It seems like using -or is common for agent nouns, but I'm unsure of which conjugation of volo to use with that.
