Hermit Thrush

Look for

A shy, brown-backed thrush with warm reddish tail, spotted breast, white eye-ring, and a habit of pumping its tail slowly up-and-down when perched — the single best ID feature.

Among Memphis's winter thrushes, the rusty tail distinguishes it from Swainson's and Gray-cheeked (both passage migrants).

Size: ~6.75" — slightly smaller than a robin, cousin of the robin and bluebird.

Listen for

• In Memphis: mostly silent, with occasional low "chup" calls. They rarely sing on the wintering grounds.
• Song (heard only if they linger into late April): an ethereal, flute-like series of phrases, each at a different pitch — often called the most beautiful bird song in North America.

Where in Memphis

Every wooded habitat with shrubs and leaf litter — forest floors, thickets, shrub edges.

• Overton Park Old Forest
• Wolf River, Meeman-Shelby, T.O. Fuller bottomlands
• Shelby Farms wooded edges
• Backyards with brushpiles

They're shy and ground-oriented — you'll see them scratching in leaf litter below shrubs.

Behavior

• Ground foragers in winter — flipping leaves with the bill, occasionally hopping into low branches for berries.
• Solitary — unlike many winter birds, they don't flock.
• Tail-pump is constant and a reliable field mark.

Story

"Swamp Angel"

The folk name "Swamp Angel" comes from the song — heard in wet Southern lowlands as the birds pass through in late spring. Walt Whitman celebrated the Hermit Thrush in "When Lilacs Last in the Dooryard Bloom'd" (1865), calling it the "singer bewildered" and using its song as metaphor for Lincoln's death.

The northernmost thrush

Hermit Thrushes breed in Canadian boreal forest and northern U.S. mountains — farther north than their cousin, the Wood Thrush. They come to the Southern U.S. for winter.

Song structure

The song is uniquely structured: each phrase starts on a slightly different pitch, but all phrases are harmonically related — musicologists have written papers analyzing the song's mathematical structure. It's one of few bird songs that follows the harmonic series of human music.

Fun facts

• The Vermont state bird.
• They're the only thrush with both resident and migratory populations in North America.
• Their berry diet in winter lets them survive much farther north than insectivorous thrushes.
• Oldest known wild Hermit Thrush: 10+ years.
