A male Rock Ptarmigan is shown Sunday on Mt. Juneau. The male Rock Ptarmigan remains a brilliant white as much as a month after females have changed color to their speckled brown. Although this increases the males chances of being nabbed by a predator it also increases their chances with the ladies, as females are attracted to the bright white color. After a female has laid her eggs the male will get his feathers dirty, dulling the white color so he has a better chance to survice while his brown feathers grow in.
