Nuthatchery
There's a nuthatch that seems interested in this birdhouse, that's right next to the house, in the current pig yard.
By "interested", I mean he/she seems super excited about it, although nuthatches always seem excited, much like chickadees.
I don't know if they've committed, but I've seen one in and out over several days, and I've even seen TWO nuthatches together at it, which is a good sign.
This is an example of a species profiting from tameness. They are comfortable being near me, and by nesting, near me, they get some measure of protection from the beasts that are not at all as comfortable getting so close to people.
Because it's a nuthatch, they don't make a traditional approach. They creep all over the house like an ant. I hope they stay and nest here.
