Squirrel but no Owl today--Don't Worry

Neither owl is spending today in the next box.  The squirrel looked in early this morning, as it has every morning.  Since the owl wasn't there, it has started bringing in materials to rebuild its nest.  Based on previous years this is perfectly normal.  Check out two previous blog entries:  Nest Prep and Courtship (posted 4/11/11) and Three Eggs and a Squirrel (3/19/12).  At least with the experienced female of past years, the owl will always win the battle.  As much as I try not to influence nature though, I am going to give the new owl(s) a break and help out.  I can see the squirrel is filling the box with plastic bags (wish I could find out where it is getting them) and I am concerned that an owl, especially a young one, may have difficultly negotiating such a mine field.  Leaves I am not worried about.  I will remove the bags just before dark tonight and let the owls take it from there.
