Random fact #4 Roosters have built-in earplugs.
Considering how a rooster's call can get up to 140 decibels or louder, it might leave one to wonder how the rooster himself keeps from going deaf when that noise is coming right out of its beak. It turns out, the farm fowl have built-in earplugs. Researchers found that when a rooster opens its beak to crow, its external auditory canals close off, preventing sound from coming in and serving as earplugs.
