  "textContent": "_Troglodytes troglodytes_ · eBird.org\n\nInfo\n\nCommon name: Eurasian Wren\nScientific name: _Troglodytes troglodytes_\n\nThe Eurasian wren packs an extraordinary voice into an impossibly small body. Barely 10 cm long and weighing around 10 grams, this round, rufous-brown bird with its characteristically cocked tail is the loudest bird in Europe relative to its body size — its song can be heard from over 500 metres away.\n\nThe generic name _troglodytes_ — Greek for “cave dweller” — refers to its habit of creeping mouse-like through dense undergrowth and root systems in search of invertebrates. It almost never migrates, and is equally at home in scrubby hillsides, dense hedgerows, forest edges, and streamsides throughout Portugal year-round.\n\nThe wren’s song is a torrent of trills and whistles, precise and mechanical — instantly recognisable once learned, and one of the most reliably present sounds in any patch of dense vegetation.\n\n* * *\n\n## Song & Call\n\nRecording XC48102 via xeno-canto.org — Creative Commons licensed.\n\n* * *\n\n**First recorded:** 26 May 2026 · Cruz de Argola, Guimarães, Portugal",
