Below are pictures of a bird called the white-tailed ptarmigan. It lives at high elevations on mountains that receive a lot of snow in the winter. During the summer, the ptarmigans’ feathers are mottled brown. The birds lose the brown feathers and grow a new set of white feathers during the winter. Scientists are concerned that rising global temperatures will affect the white-tailed ptarmigan. If global climate change leads to the elimination of snow in the habitat of white-tailed ptarmigans, which adaptation is most likely to occur over many generations? Use the drop-down boxes to create your answer. (1 point) Birds with feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have feathers throughout the year.
