In the Fall of 2013 I purchased an owl nesting box. [Read about that here.]
In November I had someone put it up in the sycamore tree that borders our driveway. [Read about that here.]
I thought it was well sited for owls, but I've had no occupants.
It sits vacant. Not even evidence of a squirrel taken up residence.
No chance it can be moved. It will be there until it falls apart and tumbles to the ground.
