Looking bizarre is still ok in this context though. The birds are socially starved captives and just seeing the shape of another bird, along with the sounds, is likely highly stimulating. I’m thinking of when my phone is in high contrast mode, it looks bizarre but it’s still totally usable for all purposes. If it was the only mode, FaceTime would still be usable to paint a general picture of what you looked like even though we have never met.
