This is what I recall of a theater movie, mid 60’s or early 70’s: night scene, outdoors looking at an office or museum window shadow of two people struggling and the death of one. Several times during the movie a bird sound is heard that I think is a peacock call.
Sure sounds like the brilliant The Bird with the Crystal Plumage (1970)
Thank you. For whatever reason the word “crystal” was in my mind and after looking at another resource, I believe this is the title of the movie I’d like to see again. This as bugged me for years now. Thanks again.
Solved!
