Chickens can fly , but they are low flying birds.
That penguins can't fly but other birds can
Yes! Some kinds of humming birds can fly above 5000 meters.
It is not only birds that fly. Bats fly and they are not birds.
I believe that the species that doesn't exist from a place that is not of this dimension do that.
Anywhere from not at all (ostrich, emu, ad other flightless birds) to thousands and thousands of miles (albatross).
Most birds can fly. Not all.
To say that birds use wings and feathers to fly, so all birds can fly, would be false. Not all birds can fly. An ostrich is an example of a bird that cannot fly.

The birds that can fly because it is easier for them to find food.
