Some birds, like the Ptarmigan, change the color of their feathers at different times of the year. In the summer months, the Ptarmigan has brown feathers. In the winter months, the Ptarmigan has white feathers. This color change allows the Ptarmigan to blend into its surroundings, no matter the season. What causes this color change to occur?

The organisms have the natural tendency to survive and adapt to their surrounding. The birds such as Ptarmigan change the feathers of the colors in different seasons.

The birds change the color of a feather because:

1. The color of the birds in the summer changes to brown color. They change colors to outwit their predators and survive.

2. In the fall, the feathers are turned white to camouflage with the snow. It provides them with higher chances of survival and outwit their predators.

Thus, Ptarmigan birds change the colors of feathers to suit the environment and protect themselves from predators.

They change their color so they wouln't be spotted by predators. Its like a self defence meckanisum ( i dont knwo how to spell) so they wouldn't get caught.
