Red-breasted nuthatch building a nesting cavity in a Cottonwood snag. West of Victor, MT near Bear Creek - 2012.03.27 this is the sixth day I have been watching this process. In the 2 minute video you get an idea how long it takes to excavate a cavity. They actually excavate up to 4 holes and choose one to raise their brood in. In the audio, you will hear a little bit of wind.
