10 Birds Cannot fly names and images | Birds that not able to fly | Walking birds Evolution: Over time, some bird species have evolved to be flightless because they no longer needed the ability to fly to survive. For example, flightless birds that live on isolated islands with no natural predators do not need to fly to escape danger. Body size: Birds with larger bodies and heavier bones are unable to generate enough lift to take flight. This is why ostriches and emus, for example, are flightless. Wing structure: The shape and size of a bird's wings can also determine its ability to fly. Penguins have short wings that are flippers, adapted for swimming and diving rather than flying. Adaptations for other functions: Some birds, such as kiwis, have developed long beaks and strong legs for foraging for food on the ground, and have lost the ability to fly as a result. Environmental factors: Environmental factors such as limited food resources or living in dense forests can also play a role in a bird's ability to fly. Over time, birds that were not able to fly would have been less likely to survive and pass on their genes, leading to a decline in the ability to fly in their species. Examples : Ostriches: The largest living species of birds, ostriches are flightless due to their large body size and heavy bones. Penguins: These birds are adapted for swimming and diving, but their short wings are not suitable for flight. Kiwis: Small, flightless birds native to New Zealand, kiwis are nocturnal and have long beaks for foraging for food in the ground. Emus: These flightless birds are native to Australia and are the second-largest living birds after ostriches. Cassowaries: Large flightless birds found in the tropical forests of New Guinea and nearby islands, they have sharp claws that they use to defend themselves.
