What is the color of the ptarmigan feathers during summer and when does it change its feathers color?
During the breeding season in spring, females change to the summer plumage that has a barred pattern of brown, black and gold. Males stay white longer, but by late summer they look similar to the females. As autumn approaches, males and females turn greyer.
What animals have Countershading?
Countershading is observed in a wide range of animal groups, both terrestrial, such as deer, and marine, such as sharks. It is the basis of camouflage in both predators and prey.
What happens to the ptarmigan in winter?
Ptarmigan are well suited to brutally cold winters, using heavily feathered feet to walk over deep snow, and excavating snow burrows in which they take shelter from the elements.
How do willow ptarmigan walk across the snow without falling in?
How do willow ptarmigan walk across the snow without falling in? In winter its feet are heavily feathered to the tips of the toes; these feathers increase the surface area of the feet and act as “snowshoes,” allowing the birds to walk easily over fresh drifts.
Where do Ptarmigans sleep?
Ptarmigan, those small arctic grouse that molt into a white plumage each autumn, spend the long winter nights in cozy caves they excavate in snow. At dusk, they dig an entrance, then bulldoze their way beneath the surface to hollow out a well-insulated sleeping chamber.

What is it called when animals change color in winter?
A key adaptive trait increasingly compromised by climate change is seasonal coat colour (SCC) moulting from dark pigmented fur or plumage in the summer to white in the winter.
Why do some animals change their Colour?
Most importantly, animals change colour in response to their surroundings (including variations in background colour, presence of predators, mates or rivals). They need to assess their surroundings so that they know what colour to change to.
What makes the animal differ in their skin coloring?

What is disruptive coloration how does it help?
Disruptive coloration (also known as disruptive camouflage or disruptive patterning) is a form of camouflage that works by breaking up the outlines of an animal, soldier or military vehicle with a strongly contrasting pattern. ... Disruptive patterns work best when all their components match the background.
How do penguins use countershading?
The most common type of marine camouflage is that used by the penguin -- a two-toned countershading. The top half of the animal is dark, so when it's seen from above, it blends in with the dark waters below it. And the bottom half is light, so when seen from below, it blends in with the sunlit waters above it.
How does countershading help fish?
Countershading, originally described in the late 1800s, is when one side of an animal is dark and the other is light, serving as a form of camouflage. ...
