How to tell it apart

Listen for: “chip-chip... zzzzzrrr”
Don't confuse with the Nelson's Sparrow. Sings a short, dry hiss, like water sizzling in a hot frying pan, unlike the Seaside Sparrow's rough opening notes and raspy buzz.

Where you'll hear it

This species occurs along the Atlantic and Gulf coasts of the United States. Many birds stay in the same marsh year-round, while some from the northern edge shift south for winter.

Seaside Sparrows live in salt and brackish marshes along tidal creeks, mud edges, and broad flats of cordgrass or needlerush. They stick close to dense, low vegetation where they can hide fast.

Spring and early summer are the easiest times to find them, when males climb stems and sing across the marsh. In winter they turn quiet and secretive, often staying buried in the grass unless flushed.

How to recognize it by sight

This marsh sparrow looks dipped in olive, gray, and brown, with a yellow glow in front of the eye. It sneaks through saltmarsh grass like a mouse, then pops up to give a dry, buzzy song over the tide.
