Dusky Thrush

Members of this diverse group make up more than half of the bird species worldwide. Most are small. However their brains are relatively large and their learning abilities are greater than those of most other birds. Passerine birds are divided into two suborders, the suboscines and the oscines. Oscines are capable of more complex song, and are considered the true songbirds. In Washington, the tyrant flycatchers are the only suboscines; the remaining 27 families are oscines.

The thrushes are a large family of songbirds found worldwide. The eight species found regularly in Washington have a diet that varies seasonally between insects and other invertebrates in the summer, and berries in the winter. Most are short-distance migrants, but some migrate to the tropics. Many of the thrushes forage primarily on the ground. The thrushes are known for their beautiful, flute-like songs, and are considered some of the best songsters in Washington.
