Native to sub-Saharan Africa, the guinea fowl is a communal bird that doubles as a guard animal. Whenever a predator is nearby, guinea fowl begin to chirp in cooperation with other guinea fowl to alert all within earshot that a predator is among them. The families at the heart of On Becoming a Guinea Fowl sure could use a couple of those early warning birds around. Then again, this movie isn’t about being a guinea fowl but becoming one. ON SCREEN: On Becoming a Guinea Fowl opens in theaters March 21.
