6 short sounds

There is some kind of critter living in the chimney above our lower-level fireplace. I am trying to figure out what it is.

I recorded 3 short-length sounds by putting a small recorder in the fireplace. Later that day I was out in the yard when I heard what sounded like it was comimg from the same type of critter. I grabbed my recorder and recorded 3 sounds from it.

What The Heck Is This Critter.
