The Grasshopper Sparrow is named for its buzzy insect-like song. The song is so strange and bug-like that you can't believe that it originates from a bird. This bird is very sensitive to changes in its habitat. If an area becomes overgrown or filled in with trees the bird will no longer nest there. There are twelve subspecies of Grasshopper Sparrow. The Florida subspecies is on the U.S. Endangered Species List because of a loss of suitable habitat.
Mostly brownish upperparts. Unmarked buffy breast. Gray and chestnut-brown streaks on nape, wing coverts and rump. White belly and undertail coverts. Back has black, white and chestnut-brown streaks.
