The beautiful flight song of this sparrow is a quintessential part of the southwest grassland habitat. Flying up from its low perch, the male then floats down with tail spread and head back in full song. Insects are its primary food during the summer, but seeds are the winter food. Some data indicate that this sparrow doe not have to drink water for most of the year and apparently makes its own water from the seeds and insects it eats. The grassy nest is placed on the ground often in the shade of low vegetation or bushes.
The four-digit banding code is CASP.
