Did You Know?
A yellow or yellowish supraloral spot (the area between the bill and the eye, just above the lore) gives the savannah sparrow's most frequently cited field mark and the feature that sorts the bird from the song sparrow, the vesper sparrow, and other streaked grassland sparrows at close range. The yellow sits small, variable in intensity, and sometimes washed out enough in winter plumage that the observer second-guesses whether the yellow existed or whether the light played a trick. A savannah sparrow with a bright yellow supraloral spot in good light at fifteen feet settles the…

"Watch closely, respect my space, and let my habitat explain the rest of the story."
The savannah sparrow (Passerculus sandwichensis) winters across North Louisiana in every open grassy habitat that stays short, stays exposed, and stays away from trees. Pastures, agricultural fields, mowed roadsides, airport margins, sod farms, levee tops, and any other expanse of short grass with exposed soil attract savannah sparrows in numbers that make the bird one of the most common wintering sparrows in the 26 parishes and simultaneously one of the least noticed. The savannah sparrow does not visit feeders. The savannah sparrow does not perch on fences for portrait photographs.
Savannah sparrow sits on the ground in a grass field, flushing ahead of the observer with a thin "tsit" note and a short, buzzy flight that drops back into the grass fifty feet ahead, where the bird disappears completely against the brown and green stubble. The birder walks forward. The sparrow flushes forward. The pattern repeats until the birder reaches the end of the field or loses patience, whichever arrives first.
A Few More Facts
How they hunt and forage: Seeds from grasses and weeds dominate the winter diet. Crabgrass, foxtail, pigweed, ragweed, and panic grass seeds get picked from the ground and from low seed heads in open field habitat. The savannah sparrow feeds by walking through short grass and picking individual seeds from the ground surface and from standing dead stems at ankle height. The feeding technique avoids the vigorous double-scratch that the junco and fox sparrow use, and the savannah sparrow's more delicate surface-picking approach tracks the bird's preference for habitat where the seed sits on or near the surface rather than buried under leaf litter. Insects compose a larger portion of the diet during spring and fall migration than during the winter months. Grasshoppers, beetles, caterpillars, and spiders picked from the grass provide the protein that the seed diet lacks, and a spring-departing savannah sparrow feeding in a Louisiana pasture in March eats grasshoppers alongside grass seeds as the bird fattens for the northbound flight. The insect portion of the diet declines during the coldest winter months when invertebrate activity in the grass drops, and a January savannah sparrow in North Louisiana eats almost exclusively seeds.

What Is the Savannah Sparrow Often Confused With?
Every short-grass field, pasture, agricultural stubble field, mowed roadside, and levee top in North Louisiana from October through April. The savannah sparrow sits as ubiquitous in open grassland habitat as the junco sits in brushy edges, and finding the bird takes nothing beyond walking through appropriate habitat and waiting for the "tsit" notes and the chain-reaction flushes. Agricultural field edges along parish roads across the delta parishes (Morehouse, Richland, Franklin, Madison, Tensas, Concordia) produce savannah sparrows in the highest densities because the agricultural landscape provides endless acres of the short, open, seed-rich habitat the bird needs. Rice stubble fields, harvested soybean fields, and mowed hayfields attract the densest concentrations. Drive slowly, stop where the fields sit low and weedy, and walk the edges. The sparrows flush ahead of you and the "tsit" notes track the flock's movement across the field.

Frequently Asked Questions
Does Savannah Sparrow live in North Louisiana?
Yes. The savannah sparrow (Passerculus sandwichensis) winters across North Louisiana in every open grassy habitat that stays short, stays exposed, and stays away from trees. Pastures, agricultural fields, mowed roadsides, airport margins, sod farms, levee tops, and any other expanse of short grass with exposed soil attract savannah sparrows in numbers that make the bird one of the most common wintering sparrows in the 26 parishes and simultaneously one of the least noticed.
The bird winters from the southern United States through Mexico, and North Louisiana receives enormous numbers of wintering savannah sparrows that spread across the region's agricultural landscape from October through April.
How do you identify Savannah Sparrow?
Every short-grass field, pasture, agricultural stubble field, mowed roadside, and levee top in North Louisiana from October through April.

What does Savannah Sparrow eat?
The Grassland Diet
Seeds from grasses and weeds dominate the winter diet. Crabgrass, foxtail, pigweed, ragweed, and panic grass seeds get picked from the ground and from low seed heads in open field habitat. The savannah sparrow feeds by walking through short grass and picking individual seeds from the ground surface and from standing dead stems at ankle height.
The feeding technique avoids the vigorous double-scratch that the junco and fox sparrow use, and the savannah sparrow's more delicate surface-picking approach tracks the bird's preference for habitat where the seed sits on or near the surface rather than buried under leaf litter.
Insects compose a larger portion of the diet during spring and fall migration than during the winter months. Grasshoppers, beetles, caterpillars, and spiders picked from the grass provide the protein that the seed diet lacks, and a spring-departing savannah sparrow feeding in a Louisiana pasture in March eats grasshoppers alongside grass seeds as the bird fattens for the northbound flight. The insect portion of the diet declines during the coldest winter months when invertebrate activity in the grass drops, and a January savannah sparrow in North Louisiana eats almost exclusively seeds.
Agricultural waste supplements the wild-seed diet in crop fields. A harvested soybean field, a rice stubble field, or a mowed hayfield with scattered seed debris attracts savannah sparrows in large numbers because the harvest left seeds on the soil surface at densities that natural grasslands rarely match. The savannah sparrow's abundance in agricultural North Louisiana tracks the agricultural calendar: fields that just finished harvest attract the highest sparrow densities, and the densities drop as the seed supply diminishes through the winter.
The first field to get plowed in spring loses its savannah sparrows to the adjacent field that still contains seed. The food supply dictated the address. The plow changed the address.
Is Savannah Sparrow dangerous to people?
No. This species is not dangerous to people when it is observed without handling or disturbance
