A - Z Challenge: Holes

Just a bit desperate this morning as I've got no holes in my schedule today.  It is hectic from now until close of play.
We're off to participate in a long-planned-for sale of  art, antiques and collectibles.  We spent last night setting it up and didn't get home until past our bedtimes.   The camera is coming along today so I can share later.

But,  for today, we have holes.   I wonder if this little guy was thrilled when he found a rock with a hole placed just so.  This is a pretty nifty little hiding place for him.  There's a back door, too.  Seconds later, he pops up on the top of this big rock - from behind.

This tree is riddled with holes.  The sapsucker has been at work drilling and  I have questions.  Like:  how long does it take to do this?  Are the holes drilled horizontally around the tree in descending rows?   Or vertically?  The rows of holes are a very wide belt around this cherry tree. 

These tiny red ants like the holes, too.  Sap is sure to attract ants to the picnic. 

And, sometimes, workin' down in the hole can just wear you out!
