Range & Seasonal Presence
The Black-throated Sparrow is the signature sparrow of southwestern deserts — creosote flats, cholla and rocky slopes, year-round in the low desert.
The Lark Sparrow breeds in open country across most of the U.S. — grassland edges, orchards and weedy fields — wintering in the Southwest where the two overlap.
Feeder Behavior & Favorite Foods
- Black-throated Sparrow: scattered seed and ground water in desert yards.
- Lark Sparrow: occasionally under feeders near open fields in winter.
- Both prefer: seed on bare open ground over elevated feeders.
- Water: desert water features draw Black-throateds reliably in summer.
Temperament & Flock Behavior
Black-throated Sparrows are dapper and confiding — hopping around desert campsites and singing tinkling songs from shrub tops.
Lark Sparrows are bold ground-walkers — strutting on bare dirt like miniature meadowlarks and delivering a rich medley from a fence post.

Do these sparrows come to feeders?
