''Amphispiza'' is a genus of birds in the bunting and American sparrow family. It contains two species: * Five-striped sparrow ''Amphispiza quinquestriata'' * Black-throated sparrow, ''Amphispiza bilineata'' It has long been considered to contain the sage sparrow complex as well, but mitochondrial DNA sequences suggest that the sage sparrow (in the broad sense) is not very closely related to the five-striped and black-throated sparrows, so it has been placed in its own genus, ''Artemisiospiza'', a treatment followed here. Both ''Amphispiza'' species inhabit dry areas of the western United States and northern Mexico, but in different habitats. They frequently run on the ground with their tails cocked and sing from low bushes. Adults are whitish on the belly and gray above and on the head, with black and white head markings. Juveniles are rather similar to each other, grayish brown above and whitish below, with short streaks on the breast. ''Amphispiza'' is from Ancient Greek ''amphi-'' (αμφι-), "on both sides" or "around", and ''spiza'' (σπιζα), "finch", originally applied to the sage sparrow; it was then considered a finch and resembles some other finch-like birds "around" it, that is, in its range. ==References== * Peterson, Alan P.
