If you have never been able to entice brown-headed nuthatches to nest in your nesting boxes, adding 1-3 inches of dry nesting material such as pine shavings, sawdust or wood chips to a nest box just might change your luck.

       I should note the only times brown-headed nuthatches have nested in my boxes is when I added nesting material.

       Who knows?  This simple technique might just work for you.
