SCIENTIFIC NAME:Ammodramus savannarum POPULATION: 31 million TREND: Decreasing HABITAT: Breeds and winters in grasslands, including prairies, pastures, meadows, and old fields.
More often heard than seen, the secretive Grasshopper Sparrow gets its name for the buzzing, insect-like quality of its songs. When seen among the dense grasses where it breeds, this small, short-tailed bird appears big-headed and large-billed compared to other sparrows.
Habitat lossand degradation remain the greatest threats to Grasshopper Sparrow and other grassland-dependent species such asBaird’s Sparrow, Long-billed Curlew, andBobolink. Increased use ofpesticides, brood parasitism by Brown-headed Cowbirds, and loss of wintering habitat have also contributed to population declines.
