Wren Song and Calls: What a Wren Sounds Like

What a Wren sounds like, with songs recorded in Britain and drawn as spectrograms: the song and its parts, how many songs one Wren sings, local dialects, when Wrens sing, and the calls. For the bird itself, see Wren identification, song and facts.

A Wren's song is remarkably loud for such a small bird: a run of high notes that ends in a trill.¹ Birds of the World describes it as long and complex: tinkling trill after tinkling trill, for seconds on end.² All About Birds gives a song as usually 4 to 6 seconds long;³ the two songs drawn on this page last about 3.6 and 4.5 seconds. In the recording below, a male on Lundy sings the same song three times, the third after a pause.

The RSPB likens the song to a flurry of high-pitched machine-gun fire, and says that more than 100 notes can be packed into a few seconds of trills, shrills and rattles.⁴ The figure below takes one song, recorded in Sheffield, and numbers its parts. We count about 50 separate notes in its 3.6 seconds; the closing trill alone holds about two dozen, packed into about 0.7 seconds.

A Wren does not have just one song. In a study at Wraysbury Lakes in Berkshire, 13 males between them sang 15 different songs, or song types, and each male had three to six.⁵ The Lundy bird above sings one of its songs three times. The Wakefield Wren below sings a different song: it opens with one two-part note repeated over and over before its trills.

Neighbouring males share many of their songs, and that can give an area its own dialect. At Wraysbury the Wrens on two banks of a lake, 200 m apart across open water, sang different sets: three song types were heard all round, but six were found only on the east bank and six only on the west, so any male could be placed on his bank by his songs.⁵

A later study of Wren song networks found that neighbouring males share many songs and can tell their group's songs from unfamiliar ones, that each male still has his own acoustic signature, and that groups of neighbours keep their vocal traditions going over the years.⁶ On remote islands, the BTO notes, Wren songs differ slightly from those of mainland birds.⁷

Wrens sing all year round, from dawn to dusk, and are heard best from March to May, in the breeding season. Dawn song seems to help hold a territory. In a playback study, males that had heard a simulated intruder sang more before sunrise the next day; singing at dusk was generally very low, and in spring males started earlier at dawn and sang more songs at dawn than in autumn.⁸

Young Wrens begin to sing in July of the year they hatch, and two adults have been reported singing hard at an adder.²

The call is a loud "tic-tic-tic", which the BTO describes as the scolding alarm call; a Wren is often heard before it is seen.⁷ Wrens also give sharp "tac" notes and loud churrs. In the lower panel of the first figure on this page, the calls form hard rattles that cover a broad band of pitches, with no tune.

Until recently, the Winter Wren and the Pacific Wren of North America were counted as the same species as ours. Birds of the World notes that the three can hardly be told apart except by their songs, and that European Wrens sing differently from the two American species.²

From the British Library's wildlife sound archive: the song of a male Wren at Loch Garten, Speyside, in 1970. Listen for the same pattern of mixed notes and trills.

All five recordings were made in Britain and shared under Creative Commons terms (the Sheffield recording is dedicated to the public domain); each was checked on a spectrogram before use. The Lundy singer is described as a male by its recordist and the Loch Garten singer by the British Library's catalogue; the Wakefield bird was photographed singing; the Sheffield song was identified from the recording by iNaturalist users. The two figures were drawn by Birdfact from these recordings.
