Grasshopper Sparrow vs Chipping Sparrow
A grasshopper sparrow and a chipping sparrow are both small, common North American sparrows, yet each is defined by a single distinctive habit, one vocal and one architectural, that has nothing to do with the other.

Grasshopper Sparrow vs Chipping Sparrow: common questions
Why is the grasshopper sparrow so easy to overlook?
The grasshopper sparrow produces a thin, insect-like buzzing trill so convincing that the sound is often mistaken for an actual grasshopper rather than a bird, and it also tends to run through dense grass rather than fly when disturbed, making it considerably harder to notice than the more visible, suburban-tolerant chipping sparrow.
Why does the chipping sparrow specifically want animal hair for its nest?
A chipping sparrow lines its nest almost exclusively with animal hair, historically horsehair collected from farms and pastures, a strong material preference distinctive enough to earn the species the old nickname hairbird, a habit the grasshopper sparrow does not share.
Which of these two sparrows is more likely to be seen in a backyard?
The chipping sparrow is far more likely to turn up in a backyard, tolerating suburban and urban landscaping well and frequently nesting in ornamental shrubs, while the grasshopper sparrow remains largely restricted to open grassland habitat and rarely ventures into developed areas.
