They are light enough and have wings.
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.

Yes, birds with long legs can fly. The only bird with long legs that cant fly is the Ostrich. The only problem is that because of their long legs they are so used to walking, so they don't fly as well as other birds.

Some birds don't fly, like penguins and ostriches, but they survive. For birds that normally do fly, not being able to do so would cause them difficulties, in terms of things like getting food and getting away from where they were born. If they were born on a high cliff or tree, then it would be difficult for them to get away if they can't fly. They could fall and die or be caught by predators. So birds that normally can fly, but aren't able to do so for whatever reason, are more likely to die.
