Savannah Sparrow

The Savannah Sparrow is a small American sparrow. It is the only widely accepted member of the genus Passerculus. Recent comparison of mtDNA NADH dehydrogenase subunit 2 and 3 sequences indicates that the Ipswich Sparrow, formerly usually considered a good species , is a well-marked subspecies of the Savannah Sparrow, whereas the southwestern subspecies should be recognized as distinct species Large-billed Sparrow .

The Savannah Sparrow is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The Savannah Sparrow (Passerculus sandwichensis) is a small American sparrow. It is the only widely accepted member of the genus Passerculus. Recent comparison of mtDNA NADH dehydrogenase subunit 2 and 3 sequences indicates that the Ipswich Sparrow, formerly usually considered a good species (as Passerculus princeps), is a well-marked subspecies of the Savannah Sparrow, whereas the southwestern subspecies should be recognized as distinct species Large-billed Sparrow (Passerculus rostratus).

The Savannah Sparrow has a large range, estimated globally at 14,000,000 square kilometers. Native to North and Central America and nearby island nations, this bird prefers marine, grassland, wetland, and shrubland ecosystems. The global population of this bird is estimated at 82,000,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Savannah Sparrow is Least Concern. More

that species, the Savannah Sparrow has a pale streak down the center of the crown, a touch of yellow on the bend of the wing, and usually a yellow spot on the front of the eye. It is one of the first winter sparrows that the beginning student of ornithology encounters in the field and should be learned at once so that it is not confused with other similar-appearing species, such as the Song Sparrow-George H. Lowery, Jr. More

Migrant and transient Savannah Sparrows have largely gone by October, at which time the first migrant "Ipswich Sparrows" arrive on the mainland (average 8 October, earliest 27 September). Both Savannah Sparrows and "Ipswich Sparrows" winter in small numbers in coastal regions. Estimates of up to 27 of the former and 10 of the latter have been made on Halifax East Christmas Bird Counts. Some "Ipswich Sparrows" winter on Sable Island; as many as 100 were counted there in winter 1969-70. More

The Savannah Sparrow is found in open habitats ranging from grassy coastal dunes, to farmland, to sub-alpine meadows. They do not need shrubs for perches, and are absent from pristine shrub-steppe habitat. They inhabit relatively small patches of grassland, and will even use disturbed and weedy areas in the open. They are common in grassy areas around towns and at the edges of irrigated fields, especially mint or alfalfa. More

Savannah sparrows were strictly migrants in Ohio during the nineteenth century. The first breeding populations were reported in several northern counties during the 1920s. Nesting pairs spread into southern and unglaciated counties during the 1970s, and Ohio is one of few states presently supporting an expanding breeding population (Robbing et al. 1986, Peterjohn and Rice 1991). Savannah sparrows are numerous in the northern and glaciated counties but rare and locally distributed in the southwestern and unglaciated counties (Peterjohn 1989). More

Savannah Sparrow is a small song bird. The most useful features are the yellow lore and fore-supercilium, and the bright pinkish legs. Yellow on lore/supercilium varies, being very pale and inconspicuous in some populations, especially in fresh plumage in autumn. Overall coloration varies from sandy brown to relatively dark brown, and intensity of streaking also variable, being finest on paler races. Streaked crown shows fairly clear whitish median stripe. The tail is notched and short. More

Upland Savannah Sparrows breed in open country such as grassy meadows, cultivated fields, pastures, roadsides, sedge bogs, and coastal grasslands, favoring areas of dense ground (especially grass) vegetation and moist substrates and avoiding areas of extensive tree cover (Wheelwright and Rising 1993).

Although they are grassland-loving birds, Savannah Sparrows were named not for a grassy habitat with scattered trees, but for Savannah, Georgia, where Alexander Wilson took an early specimen. The Savannah Sparrow is a variable species with a very broad range. During the breeding season it is found in open habitats across Alaska and Canada south to the middle United States and in the west south to Mexico. More
