This most abundant and familiar of the grass sparrows has a stubby notched tail, rather than the shorter and more pointed ones of other sparrows. His head is brown with a grayish crown stripe. Underparts are whitish. It ranges throughout most of the United States. The "Savannah Sparrow" was first discovered in Georgia by Alexander Wilson in 1811.
Both sexes look alike.
The "Savannah Sparrow" flies only occasionally - low, erratic flights, a few feet at a time.
The "Savannah Sparrow" breeds from Alaska east across Canada and south to New Jersey, Missouri and northern Mexico. In courting season, males chase each other and display to the females by vibrating their wings, either on the ground or in flight.
Calls or song.
Songs of the male "Savannah Sparrow" sung from perches or in flight, and sometimes while foraging, are persistent, high-pitched and buzzy, sounding like "tzip-tzip-tzip ztreeeeeee-ip".
Population and distribution.
In the fall huge numbers of these sparrows migrate southward and may be found almost anywhere.
Mated birds build their nests in a hollow. In a cup of stems and moss, the female "Savannah Sparrow" lays four or five bluish, rust-speckled eggs, which both parents incubate.
