Time to Prep Bluebird Nest Boxes for Nesting Season

I think sometimes we forget to prepare our nest boxes for the coming nesting season.  Bluebirds should be looking for nesting sites soon.  Now is a good time to make sure nest boxes are cleaned out.  If last year's nests weren't cleaned out they should be.  Also mice sometimes move into nest boxes in the winter.  Paper wasp nests are another issue. Look for their nest attached to the inside roof of the box.

And if you live where there are house sparrows be prepared for them to compete with the bluebirds.  I find using nest box traps a good way of dealing with the house sparrows.  Here is my video on "How to trap house sparrows in a nest box"
