Birds Do It

I love seeing birds in their nests and I know humans like to be cozy, too.  This Nestrest seems to fit the "bill".   There is something about the serenity of the photo of one over the river, that really looks wonderful.  (but you've got me, how he got in there and stayed dry!)

 It kind of reminds me of being a kid and making a fort to hang out in and read a book.  That was one of my favorite pastimes.  And as you can see below, you can go solo, or bring the rest of the flock.

So tell me, do you have your own private refuge?  What does it look like?  Do you have a special pastime/craft/activity for it?
