The Hermit Thrush (Catharus guttarus) is a songbird that lives in forests across North America. It winters in our area. Hermit Thrushes don't migrate very far. The ones who winter in our part of the Central Valley likely spend their summers in the forests of the Sierra Nevada. It's diet--which consists of insects and wild berries, such as hackberries--is easily fulfilled here.  The Hermit Thrush has a distinctive flute-like song.
