Downy Woodpecker

Downy Woodpecker 
 


Fun Woopecker facts:
  • Woodpeckers have a third eyelid to help protect their eyes from debris.
  • A woodpecker's head can strike at speeds up to 15 mpg at over 100 strokes per minute.
  • The bones between the beak and the skull are joined by a flexible cartilage.
  • The skull is made of spongy, air-filled bone. The brain is packed tightly into the brain cavity, with little room to rattle around.
  • The force from each strike is directed towards neck muscles that act as shock absorbers.
