shade of darkish gray. Bell's
Sparrow also has a thicker malar strip than sagebrush. The amount a streaking on the back as well as the shade of the mantle may also be used to separate the two, but this is affected by wear on the feathers. Bell's also has little or no white in the tail, but this field mark alone may not be diagnostic.

Bell's sparrow is difficult to separate in the field from the sagebrush sparrow. Both species measure about 6 in (15 cm) long and weigh approximately 16.5 g (0.58 oz). In general, with Bell's
Sparrow the malar is darker than the head while on the sagebrush it is about the same

since 1977. This subspecies has grown in numbers since then as a result of conservation efforts conducted by the US Navy, resulting in the regrowth of native vegetation. and has been proposed for removal from the
Endangered Species Act by the US Fish & Wildlife Service.
