Animal Tracking: Can You Guess Who Done It?

A specific creature has created the holes you see in the tree trunk above. See all the shavings on the ground underneath it?
Can you guess which species it is that does this !?!

Here's some hints:

• It's rarely seen
• It's bigger than your head
• It's not a unicorn sharpening it's horn
  

Ya'll try to guess what it is, and I will tell you the answer in a few days!!!
