Happy World Penguin Day! 🐧 There is always something exciting to see at the Polk Penguin Conservation Center at the Detroit Zoo – like these two gentoos nesting! Watch as one penguin scurries down to retrieve a fallen rock and is not satisfied until the nest is perfect. Continue through this immersive building to learn about our conservation work in the Falkland Islands and visit the World Penguin Day education station to learn interesting penguin facts. #DetroitZoo #WorldPenguinDay #Penguins
