I was shocked - shocked and stunned - Saturday morning when I saw a pair of bluebirds in my backyard. While I am becoming profligate with the wren houses, I dismissed the idea of adding a bluebird nesting box to the landscape because I thought my backyard habitat was too suburban. But no, here were a pair of bluebirds trying to set up housekeeping in one of the wren houses. I needed a bluebird box right now.
Life intervened, though, so I was not able to get the box until Sunday, and as soon as I got home, it went up on the post where the wren house had been (since moved to the front yard). And, of course, I have not seen the bluebirds since.
