California quail are the most widely distributed upland game birds in Oregon. Most easily recognized by the comma-shaped, black, plume, or "topknot," which bends forward and is larger on the male.
It has been a resident statewide since the early 1900s, except for most forests of the north Coast Range and west Cascades; it is generally absent along the coast north of Coos Bay. California quail is also absent from high-elevation areas of the east Cascade range. They are common residents in rural and even some suburban areas, particularly in eastern Oregon where many coveys gather at feeding stations during the winter.
