Ostrich and penguins are flightless birds because unlike most birds, their flat breastbones lack the base that anchors the strong pectoralmuscles required for flight. Their weak wings can’t possibly lift their heavy bodies off the ground. Thank you po ☺️☺️☺️☺️.
Penguins (order Sphenisciformes / sfɪˈnɪsɪfɔːrmiːz /, family Spheniscidae / sfɪˈnɪsɪdiː /) are a group of aquatic flightless birds. They live almost exclusively in the southern hemisphere: only one species, the Galápagos penguin, is found north of the Equator.
One way to consider this is flightless Bird Mystery Solved, Say Evolutionary Scientists Ostriches, emus, moas, and other flightless birds of the world evolved flightlessness separately. Large flightless birds are scattered across all but one of the world’s southern continents.
When we were writing we ran into the inquiry “What are flightless birds called?”.
Flightless birds are birds that cannot fly but they can run and/or swim instead of flying, but they did evolve from flying ancestors. There are about 40 species in existence today, the best known being the ratites ( ostrich, emu, cassowary, rhea and kiwi) and the penguins.
Why don’t Penguins fly?
“High flight costs, but low dive costs, in auks support the biomechanical hypothesis for flightlessness in penguins”. Proceedings of the National Academy of Sciences., and doi: 101073/pnas1304838110.
Why can’t Penguins fly?
Scientists believe penguins can’t fly because they likely had little or no threat from predators in their past. That means they never evolved to fly because they didn’t have anything to fly away from. They relied on the oceans for food, so developing flippers to swim well was more important than growing wings to fly.
Why can’t ostriches fly?
Ostriches, emus, cassowaries, rheas, and kiwis can’t fly. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight. Their puny wings can’t possibly lift their heavy bodies off the ground. These flightless birds, called ratites, are clearly different from other avian species.

Is a penguin a bird or animal?
Flightless aquatic bird. Penguins (order Sphenisciformes, family Spheniscidae) are a group of aquatic, flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galapagos penguin, found north of the equator.
