PROBLEM: Question: Is there a single word to describe birds that can fly? Am I struggling to think of a word because the default notion of a bird is that it can fly? So we generally only need to differentiate the ones that can't fly. I've seen the term "winged" in a few google searches, but to my mind an ostrich is winged, but it is also flightless.
