The actors are elegant in slo-mo, and they'll work for chicken feed. Squirrels will work for peanuts.

True.

I regret that I didn't identify the tune in the soundtrack. Beautifully played. Does it have lyrics?

Music: Nocturne by Asher Fulero, courtesy of Youtube audio library. People contributed original work to the audio library that you can use without violating copyright. I like to give them credit, as they have professional studios and often do movie score work. Check your indie films and you might see some of the names from Youtube's audio library.

Fat, lazy, rich birds don't need to fly at all. They just buy airline tickets.
