Which of these birds can't fly?

• Penguin:Penguins are flightless, aquatic birds with wings. Unlike the wings of other birds, penguins' wings are more like flippers that make them well-suited for life in the water. Scientists believe penguins lost their ability to fly as a result of having faced little or no predators in their past. That means they never evolved to fly since they had nothing to fly away from. Instead, these birds evolved to become more aquatic to better survive in their habitat. Because they were dependent on the ocean for food, developing flippers to swim was more crucial than growing wings to fly.
