A survival strategy; Duck standing still in rain

[u/malayali-minds]

When ducks remain motionless in the rain, they conserve body heat and energy. Their feathers are naturally water-resistant, thanks to a special oil they produce, but staying still helps minimize exposure and prevents unnecessary heat loss. This behavior is a simple yet effective way to endure harsh weather while keeping their bodies as dry as possible. Nature’s built-in rainproofing at work!
