What the Nelson's Sparrow sounds like

A tiny, secretive sparrow of wet marshes, Nelson's Sparrow glows with a warm orange face, a neat gray cheek, and crisp streaks down the chest. It usually stays low in the grass, then suddenly pops up for a quick look before vanishing like a mouse through the reeds.

How to tell it apart

Listen for:The song is short, thin, and insect-like—a dry hissy buzz with a tiny sharp ending. It can sound more like a strange marsh bug than a bird. Often written as tss-kzzzz-tik.
Don't confuse with:The Saltmarsh Sparrow — usually has a stronger face pattern with a darker cheek patch and less clean gray on the face.

Where you'll hear it

Look for it in coastal salt marshes, wet meadows, and shallow freshwater marshes thick with sedges and grasses. It likes places that feel soggy, tangled, and a little hard to walk through.

They're easiest to find during migration and winter high tides, when rising water pushes them into view. On the breeding grounds, males sing from low stalks but still spend lots of time hidden in cover.
