Are you aware of, or have thought of something in nature that could totally end up as a prop in film? For example the Golana Melon in this Star Trek: DS9 episode is actually a Kiwano (Cucumis metuliferus). My choices:
My trained ish birder ear usually get thrown off by some weird background bird noises from places where there shouldn’t be birds of that type. Not sure if that counts as a movie prop, but yeah.
I think so! I sometimes hear local Crows (Corvus)(?) making that throaty sound (not sure what it is, not a birder!) and it definitely sounds un-bird-like to my untrained ear.
I remember watching a movie of an alien landscape on a distant planet and it was pretty convincing until I recognized the ocotillo.
“Huh - southern California or thereabouts.”
I was shocked when I first saw an Ocotillo when I visited Arizona last year. I had never seen or even heard of one before and my first thought was that it was one of Dr. Seuss’ illustrations come to life!
