What the Willow Ptarmigan sounds like

A chunky, chicken-like bird of Arctic willow scrub, the Willow Ptarmigan is famous for changing outfits with the seasons. In summer it wears warm chestnut and brown; by winter it turns nearly pure white and can seem to disappear into the snow.

How to tell it apart

Listen for:The male’s main display is a rough, rolling croak-cackle tossed out from a hummock or low rise. It sounds froggy, rusty, and wonderfully wild in open tundra air. Often written as go-back, go-back, go-back!.
Don't confuse with:The Rock Ptarmigan — usually favors rockier, more open tundra and higher ground.

Where you'll hear it

Look for it in low, shrubby country in the far north—willow thickets, boggy tundra, muskeg, and brushy stream edges. It likes a mix of cover and open ground.

Spring is the noisy season, when males stand on hummocks, flash red eyebrow combs, and croak out display calls. In winter, small flocks feed quietly and may dive into soft snow to roost out of the cold.
