Cool Facts

The Sibley Field Guide to Birds of Western North America by David Allen Sibley
  • The "Ipswich Savannah Sparrow," a subspecies that breeds on Sable Island, Nova Scotia, is nearly 50 percent heavier than most other Savannah Sparrow subspecies. It is the palest race, and is found in winter in sand dunes along the Atlantic Coast. It was formerly considered a separate species.
  • In many parts of the species' range, especially in coastal areas and islands, Savannah Sparrows tend very strongly to return each year to the area where they hatched. This tendency, called natal philopatry, is the driving force for differentiation of numerous Savannah Sparrow subspecies.
  • Of the 17 recognized subspecies, 6 are resident or partially migratory in salt marshes in California and Mexico.
  • It is named after Savannah, Georgia, where one of the first specimens of this bird was collected.
  • A group of sparrows has many collective nouns, including a "crew", "flutter", "meinie", "quarrel", and "ubiquity" of sparrows.

  • Many birds of open country, including other sparrow species, are also brown and streaked.
  • Vesper Sparrow has a bold white eyering and white outer tail feathers.
  • Song Sparrow is larger, with a longer tail, a rounded tail tip, and a thick mustache stripe. Shows large chest spot, but Savannah can show one too.
  • Species of the genus Ammodramus, such as Grasshopper Sparrow and Baird's Sparrow, show buff tones in the face and breast, and have unnotched, often spiky tails

Conservation Status

In general, the Savannah Sparrow has probably expanded its range and thrived because of human-induced changes to the landscape. Coastal subspecies and other populations with narrow ranges may warrant special management priority because of their genetic distinctiveness and their limited habitats.
