§ Identification

Field marks. Highly variable across regions but always with a pale pink bill, dark hood/upperparts, white belly, and white outer tail feathers. 'Slate-colored' is gray; 'Oregon' has a dark hood and rufous sides.

Similar species. The pink bill, clean white belly, and flashing white tail edges separate juncos from other sparrows. Multiple regional forms once considered separate species.
