I agree with Learnin, appears to be a screech owl.
Is it small?
The Missouri owls with "ear" tufts have the following adult heights:
Screech 8"
Long-Eared 15"
Great Horned 22"
The most times I have seen (and heard) screech owls is when they had two nesting pairs in the parking garage of one of our area hospitals. There were hollow steel beams with small holes used in the construction. The screech owls really enjoyed their steel-reinforced, secure homes!
The best part was if you went to the hospital after sundown, they sometimes would be emitting awesome screeches that reverberated through the concrete parking garage. Many people were freaked out by the racket, but I loved it.
P.S. The literature says your red morph is the rarest of the Missouri screech owls. Any chance you can put up a few more log homes like the one the owl already picked? It would be nice to help their population numbers a little.
