Wearing white camouflage was not invented by the Alpine troops. This discovery is to be attributed both to the mountain hare and another arctic-alpine relict, the rock ptarmigan (Lagopus mutus). This cousin of the black grouse trades its summer grey-brown plumage for an entirely white camouflage in winter. And as if this adaptation to the snowy environment were not enough, the bird has also evolved to have furry boots! Its entire claw up to the tip is feathered&hellip, you guessed it, in white.
