Bell’s Sparrow
Bell's Sparrow
Artemisiospiza belli
At a Glance
Formerly considered part of the same species as the Sagebrush Sparrow, this bird is locally common in sage scrub habitat near the California coast and locally in open habitats of the interior. It is often seen running about on the ground, with its longish tail cocked up above the level of its back; when perched up on a shrub, it twitches its tail in a down-up motion like a phoebe.
