Savannah Sparrow
|
|
Passerculus sandwichensis |
From meadows to marshland, and from temperate coastlines to tundra, the Savannah Sparrow is found in various open habitats throughout much of North America. It varies widely across its range, with 17 recognized subspecies.
Interesting Information
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.
