Ask an Explainer
Q:
Could the reason why some birds don't fly be that they don't have a good airfoil?
A:
Yep! The shape of some birds' wings is one reason some types of birds can't fly or can't fly as well as other birds. Birds that fly must be lightweight, strong enough to overcome gravity, and have properly shaped wings. Birds that don't fly generally are missing one or more of these factors.
