Rock ptarmigan
*Lagopus muta*, known as the rock ptarmigan, is a cold-adapted bird found in Arctic and alpine regions across the Northern Hemisphere. It changes plumage seasonally—white in winter for snow camouflage, mottled brown in summer. This ground-dwelling bird feeds on buds, leaves, and insects. It’s well-insulated, with feathered legs and feet, and survives harsh environments with minimal shelter.
