Acorn Woodpeckers are the most common woodpecker species that we see in the Sacramento, CA area. They are very active, industrious, and highly social birds. They live in family groups in a single nesting cavity, they manage a large acorn granary stored in holes they drill in dead trees, and they are very territorial.
One of the California Naturalists at Effie Yeaw Nature Center, wrote a short, interesting article about them. The article was published in “The Acorn” summer newsletter from Effie Yeaw Nature Center. (2021acornsummer.pdf (capitoltechsolutions.com)). It is a fascinating read sure to increase your appreciation of the interesting birds.

The cavity is a Starling nest. The Acorn Woodpecker came to investigate the nest. It was chased away by the Starling.

I’m always entertained watching the Woodpeckers work their granary’s. They’ll wreck havoc on just about anything made of wood.
