Hey Dave. I had one a few weeks ago I posted a pic in the birdwatching post. I think we are a little to far north for them to hang all winter.
I will say this though they head up this way a lot earlier than most people think. You need to have the boxes cleaned out and ready very early in spring to attract a male. If there is anything left in the box it will move on. I have had them raise 2 sets of babes in one summer. I cleaned out the old nest and he was back with another mate a few days later. It is all about the female. They decide if they want that box or not. Just like humans
. One year I had several look but they were all just tire kickers. I had none stay last year but I did see 2 check it out.
