Systematik: Gattung Passerculus (Passerculus); Familie Passerellidae (Passerellidae)Allgemein:
The Savannah sparrow (Passerculus sandwichensis) is a small New World sparrow. It was the only member of the genus Passerculus and is typically the only widely accepted member. 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 a distinct species (Passerculus rostratus).[2]
