Birds use several adaptations to survive cold weather:
- Feathers: Insulate and trap warm air close to the body.
- Body size: Smaller birds lose heat faster and often have higher metabolic rates.
- Storing fat: Fat reserves provide insulation and energy.
- Huddling or Roosting: Clustering together reduces heat loss.
- Behavioral adjustments: Seeking shelter and reducing activity conserves energy.
- Migrating: Some species travel to warmer climates.
- Torpor: Reduced body temperature and metabolism help conserve energy.
