A bird is able to fly on Earth because it is able to create "lift" with its wings--currents of air hold it aloft. This explains why birds with large wings such as condors appear to flap little because the size of the wing maintains their flight. Since there is no "air" in space, our bird would not be able to fly.
Another reason why the bird would not be able to fly in space is the same reason a person would not be able to survive without a spacesuit and/or a rocket in space--solar radiation, pressure differences and a lack of breathable air would kill the bird. Nitrogen bubbles would form in the bird's blood and cause swelling, and the extreme cold of space would also assist in killing our unfortunate bird. All of this would not happen immediately, but would happen in minutes.
