Nuthatchlings

We have a birdhouse in our back yard that we bought from Ukrops a number of years ago. I put it up in our back yard before the spring of 2006. Since then a different species of bird has made that house its nest and has raised baby birds in it. In 2006 it was chickadees, and in 2007 it was titmice (or titmouses? - the bird does not seem to have anything to do with the small mammal).

This year, in 2008, it is nuthatches. I have seen nuthatches go in and out from that house, so I felt there were nuthatchlings in that box. I went out there today and took a picture. Sure enough, there were nuthatchlings there - six of them. They are almost fully grown, so any day now I can expect to see about half a dozen nuthatches in our back yard. Here they are: .

What will it be next year? I originally bought it advertised as a bluebird house, but bluebirds have rejected it.
