Why could dodo birds not fly?

Why could dodo birds not fly?

So why was the dodo confined to two legs? As natives of an island with no predators the ancestors of the dodo no longer needed flight as an adaptation to escape. Flying is energetically costly, so over time it was not favoured by natural selection, and flightlessness was passed on to subsequent generations.

How a species of bird on a remote island could lose the ability to fly over time?

“It’s easy to see why a diving bird like a cormorant or a ground-dwelling one like a kakapo might lose its ability to fly when predators are absent.” If such predators are absent, birds can take off at a more leisurely pace, and they can afford to have smaller (and cheaper) flight muscles.
