The Red Breasted Nut Hatch and White Breasted Nut Hatch both frequent most all of the US. The Nut Hatch likes its house to be attached to a tree. Their hole size should be 1 1/8th inch to 1 1/4 inch, the same as a chickadee or wren. Putting up a Nut Hatch house doesn’t mean that is the only bird that may nest in it. They like to nest in the woods which will make it difficult to watch this bird. Floor space should be 4″ x 4″ and they prefer an A-Frame type house. This shape makes it very difficult to put in a clean out door. Many of the wren or chickadee houses will dupe as a Nut Hatch House and they have clean out doors.
