Hey! :)
Some birds cannot fly. For eg: ostriches, cassowaries, emus and rheas. These birds can't fly because they have puny wings i.e. their wings are lethal and small, which is unable to lift their heavy body weight. Also, these birds mentioned above, have their breastbones lacking the kneel that anchors the strong pectoral muscles required for flying.
...hope this helps :)
