The '''Grasshopper Sparrow''', ''Ammodramus savannarum'', is a small [[American sparrow|sparrow]]. The ''Ammodramus'' genus of 11 species inhabit [[grassland]]s and [[marsh]]es.
Adults have upperparts streaked with brown, grey, black and white; they have a light brown breast, a white belly and a short brown tail. Their face is light brown with an eye ring and a dark brown crown with a central narrow light stripe. There are regional variations in the appearance of this bird.
Their breeding habitat is open fields and [[prairie]] across southern [[Canada]] and the [[United States]]. The nest is a well-concealed open cup on the ground under vegetation.
These birds [[bird migration|migrate]] to the southern United States, [[Mexico]], [[Central America]] and the [[Caribbean]].
They forage on the ground in vegetation, mainly eating insects, especially [[grasshopper]]s, and seeds.
This bird's song is a buzz resembling the sound made by a grasshopper. Like many grassland birds, this bird's numbers have declined across many parts of its range, including a 98% drop in New York State.
