The hermit thrush (Catharus guttatus) is a medium-sized North American thrush. It is not very closely related to the other North American migrant species of Catharus, but rather to the Mexican russet nightingale-thrush.
This species measures Script error: No such module "convert". in length, spans Script error: No such module "convert". across the wings and weighs Script error: No such module "convert".. Among standard measurements, the wing chord is Script error: No such module "convert"., the bill is Script error: No such module "convert". and the tarsus is Script error: No such module "convert".. It is more compact and stockier than other North American Catharus thrushes, with relatively longer wings. The hermit thrush has the white-dark-white underwing pattern characteristic of Catharus thrushes. Adults are mainly brown on the upperparts, with reddish tails. The underparts are white with dark spots on the breast and grey or brownish flanks. They have pink legs and a white eye ring. Birds in the east are more olive-brown on the upperparts; western birds are more grey-brown.
Hermit thrushes migrate to wintering grounds in the southern United States and south to Central America but some remain in northern coastal US states and southern Ontario. Although they usually only breed in forests, hermit thrushes will sometimes winter in parks and wooded suburban neighbourhoods. They are very rare vagrants to western Europe. It has also occurred as a vagrant in northeast Asia.
They forage on the forest floor, also in trees or shrubs, mainly eating insects and berries.
The hermit thrush's song has been described as "the finest sound in nature" and is ethereal and flute-like, consisting of a beginning note, then several descending musical phrases in a minor key, repeated at different pitches. It often sings from a high open location. Analysis of the notes of its song indicates that they are related by harmonic simple integer pitch ratios, like most human music and unlike the songs of other birds that have been similarly examined.
Walt Whitman construes the hermit thrush as a symbol of the American voice, poetic and otherwise, in his elegy for Abraham Lincoln, "When Lilacs Last in the Dooryard Bloom'd," one of the fundamental texts in the American literary canon. "A Hermit Thrush" is the name of a poem by the American poet Amy Clampitt. A hermit thrush appears in the fifth section ("What the Thunder Said") of the T. S. Eliot poem The Waste Land.
The song of the hermit thrush is audible in the "Garden" stage of Super Mario Galaxy for the Nintendo Wii.
A slightly altered song of the hermit thrush was used for the Mockingjay's song in the early scenes of the film The Hunger Games. The hermit thrush's song, as well as the house wren and mourning warbler are all very common in modern-day media.
The character Raymond Tusk identifies the song the hermit thrush when protagonist Frank Underwood meets with him in St. Louis, in the 12th episode of the first season (titled "Chapter 12") of the Netflix television series House of Cards.
