Correct. Variability within an apparently huge range that DNA already had in-built. It does NOT change the kind of bird.
If you get a chance to view the Ray Comfort video I posted “Evolution vs. God”, he presents this argument clearly and then shows how the ‘evolution ethic’ has permeated our society. He asked a few students about their views of evolution and then after gave them a moral situation. It went like this: if your dog and neighbor next door were drowning in a river and you could only save one, which one would you save? You will be amazed (maybe not) of the answers. Out of about 5 or 6 students only one said the neighbor!
