Grasshopper Sparrow
Ammodramus savannarum (Gmelin, 1789)

Habitat [-]
Habitat preferences include open grasslands with some bare areas (Bollinger 1995, Whitemore 1981) that are typically far from cultivated fields, fence lines, and woods (Wiens 1969). In New York, Bollinger (1995) found Grasshopper Sparrows most frequently in old, grass-dominated hayfields with litter cover that he described as shorter, sparser, and patchier. Nests are hidden in grass.

Associated Ecological Communities [-]
  • Cropland/field crops
    An agricultural field planted in field crops such as alfalfa, wheat, timothy, and oats. This community includes hayfields that are rotated to pasture.
  • Successional old field
    A meadow dominated by forbs and grasses that occurs on sites that have been cleared and plowed (for farming or development), and then abandoned or only occasionally mowed.

Associated Species [-]
  • Savannah Sparrow (Passerculus sandwichensis)
