Birds are quite muscular. If you have ever eaten chicken, that meat is muscle.
After the pectoralis major, the next most important muscle in the birds is triceps. It is highly developed muscle in birds and used to extend the wings.
Of all the birds in the world, hummingbirds are the best fliers. One of the things that makes them great fliers is the size of their chest. All birds have two chest muscles, one to raise the wings, and one to lower them. When the first muscle contracts it pulls the wings up. When the other muscle contracts it pulls the wings down. Most birds have small muscles for raising their wings. All their power comes from the downbeat. But hummingbirds have big muscles for raising and lowering their wings. They are the only birds that get flying power from both wingbeats. That is why they are such superb fliers.

Most birds use their wings for flight. Some of the flightless birds, or birds which do not fly much, may use their wings just for balance, especially when perching (e.g. chickens). For some flightless birds such as the kiwi, their wings appear to be without purpose.
if you use the birds DNA, then yes, as the birds DNA doesn't say *no wings*
