How have birds adapted to live in the antarctic?

Answer 1

The 45 species of Antarctic birds tend to have...

• Thick inner down feathers for warmth
• Oily and waterproof outer feathers
• A greater proportion of tendons to muscles (muscles lose heat more quickly than tendons),
• Black, grey, white, and brown colors for camouflage
• Short tails and extremities to minimize heat loss
• Antarctic breeders use stones rather than vegetation for nests

All birds in the Antarctic rely on the ocean for food, and all 45 species swim or dive to some degree.

Answer 2

because they can migrate in the winter
