NOTES:

Gregarious, forming coveys of up to 200 (rarely to 300+) birds in fall and winter. Male acts as sentry throughout year. Female broods chicks. Remain on ground and run very rapidly, flying as last resort. Roost in dense trees or shrubs, not on ground.

STANFORD. NOTES:

Uncommon and rapidly declining on campus, this species is now present primarily in southern portions of campus, where it forages in grassy habitats or under oaks and uses dense brush and ornamental plantings for cover. Historically common throughout but now extirpated from many areas, probably due to predation by cats. As recently as the early 1990s, coveys of quail could be found in the Arboretum and around the Oval, but these birds have mostly disappeared.

ESSAYS:
