Ostriches and penguins lack the ability to fly primarily due to evolutionary adaptations suited to their environments. Ostriches have evolved to be large, Flightless Birds that are excellent runners, allowing them to escape predators on land. Penguins, on the other hand, have adapted to an aquatic lifestyle, developing strong wings that function as flippers for swimming rather than flying. These adaptations have made flight unnecessary and even disadvantageous for their survival.

Does a bird die if it doesn't fly?

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.
