An outspoken penguin brayed and bleated at the Blank Park Zoo in Des Moines, Iowa, on January 20.
Footage taken by the zoo shows the penguin, identified as Penguin 86, opening its mouth and emitting loud bellows.
“Penguin 86 was braying up a storm this morning,” wrote Blank Park Zoo on Facebook. “Braying is a form of vocalization and is used as a way to communicate. Look closely to see the serrations in his mouth. They are useful for catching fish and guiding them down his throat.” Credit: Kelsey Anderson/Blank Park Zoo via Storyful
