The colors of the owl are really relevant as it helps the owl survive and get away from its predators. The owl needs the feathers to provide warmth during the winters. The Owl Research Institute stated that feathers are not the only mechanism that the grey owl possesses. They have various other tricks up their sleeves.
Owls can conceal themselves by standing tall or pulling in their size. They can look skinnier and taller and it gets harder to spot one. When the owls try to pull these concealment moves, they raise their white feathers around the bill.
