Nesting Habits Red-breasted Nuthatch

Beginning in late April early May, the Nuthatch pair begins excavating a cavity nest in a dead tree.

The nest site can be anywhere from 5 to 100 feet above ground. Although 15 feet above ground is about average. Sometimes uses bird houses.

Inside the cavity, bark strips, grass and plant fibers are placed at the bottom for nesting materials.

An interesting note about these birds is their habit of placing droplets of resin, or pitch, from balsam fir, or pine trees to smear around the entrance hole of the nesting site.

This practice continues throughout the nesting phase, resulting in an area sometimes 2 inches or more smeared with the sticky substance.

The reason for doing this is really unknown.

Speculation is to keep ants and small mammals from entering since they have to walk or crawl through the pitch.

The Nuthatches themselves are able to fly straight into the hole without being affected by the pitch.

The female lays 4 - 7 eggs that are white and finely spotted with brown. Incubation last about 12 days. Sources differ on whether the female or both male and female incubate.

The young leave the nest 18 - 21 days after hatching.

Feeding Habits/What They Eat

Their diet consists of conifer seeds and insects. Watching them at the bird feeder you can see them take a single sunflower seed, fly away to a branch, and eat it before returning for another.

Another must have is a suet feeder. All the nuthatches will come to a suet feeder.
