There was a bird, an eagle or hawk I think, in a building. The building might have been under construction, and quite possibly it was a high rise apartment or maybe an office in a skyscraper.
The bird plot/storyline was referenced throughout the movie, but I think it was a subplot, not the main thing. It seems like maybe one of the characters kept dreaming about it or some characters thought it was imagined.
It was in English, and in color. Live action, and the main characters were adults. Sorry it’s not much to go on.
“Brewster McCloud” (1970)??
Q?

Great guess Roxanne. I forgot about the feathered serpent god, Quetzalcoatl!
Lol and I didn’t realize it says it’s or Eagle like. I remember watching it too and also forgot the title. Thx to internet.
