The Savannah Sparrow (Passerculus sandwichensis) is a small American sparrow. It is the only widely accepted member of the genus Passerculus. Comparison of mtDNA NADH dehydrogenase subunit 2 and 3 sequences indicates that the Ipswich Sparrow, formerly usually considered a valid species (as Passerculus princeps), is a well-marked subspecies of the Savannah Sparrow, whereas the southwestern Large-billed Sparrow should be recognized as distinct species (Passerculus rostratus).
The common name comes from Savannah, Georgia, where one of the first specimens of this bird was collected.

Famous quotes containing the word sparrow:
“A sparrow enters the tree,
Whereon immediately
A snow lump thrice his own slight size
Descends on him and showers his head and eyes,
And overturns him,”
