Melospiza georgiana
Conservation status | Undoubtedly has declined with loss of marsh habitat, but still widespread and common. Localized salt-marsh race on Atlantic Coast could be vulnerable to habitat loss. |
---|---|
Family | New World Sparrows |
Habitat | Fresh marshes with tussocks, bushes, or cattails; sedgy swamps. Breeds mostly in freshwater marshes with good growth of sedges, grass, or cattails, often with thickets of alder or willow; sometimes in swampy thickets around ponds and rivers. Also breeds locally in salt marshes on middle Atlantic Coast. During migration and winter found mainly in marshes, but also in streamside thickets, rank weedy fields. |
Forages mostly on the ground, especially on wet mud near the water's edge, and sometimes feeds while wading in very shallow water. Also does some foraging up in marsh vegetation.
4-5, sometimes 3-6. Pale green to greenish white, heavily marked with reddish brown. Incubation is by female only, probably about 12-13 days. Male may feed female on the nest during incubation. Young: Both parents bring food to the nestlings. Young leave the nest about 10-13 days after hatching. Often 2 broods per year.

Mostly insects and seeds. Feeds heavily on insects, perhaps more so than related sparrows, especially in summer. Diet includes many beetles, caterpillars, grasshoppers, crickets, ants, and many others, as well as other arthropods. Also eats many seeds, especially in fall and winter, including those of grasses, weeds, and sedges.
To defend nesting territory, male sings from a raised perch, such as the top of a cattail or a shrub in the marsh. May sing by day or night. Nest: Placed in marsh vegetation such as cattails, sedge tussocks, or bushes, often directly above the water, up to 5' high; perhaps sometimes on the ground. Nest (probably built by female only) often has bulky foundation of coarse grass and other marsh plants, with inner cup of fine grass. Dead cattail blades or other leaves often arch over the nest, so that the birds must enter from the side.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

Birds can lose their singing skills over time, and according to a new study, Swamp Sparrows use these clues to identify territorial threats.
By memorizing the common local language and sifting out the rest, young sparrows choose tradition over variance.
