The Eurasian wren (Troglodytes troglodytes) is a very small insectivorous bird and the only member of the wren family found in the Old World, specifically in Eurasia and Africa (Maghreb). In Anglophone Europe, it is commonly known simply as the wren. It has a very short tail which is often held erect, a short neck and a relatively long thin bill. It is russet brown above, paler buff-brown below, overall finely barred darker, and has a cream buff supercilium. The sexes are alike.
The Eurasian wren occurs in Europe and across the Palearctic, including a belt of Asia from northern Iran and Afghanistan across to Japan. It is migratory in the northern (particularly northeastern), parts of its range, and sedentary in the west and south of its range. It is also highly polygynous, an unusual mating system for passerines. The species was formerly lumped together with winter wren (Troglodytes hiemalis) of eastern North America and Pacific wren (Troglodytes pacificus) of western North America under the merged name of northern wren.
The scientific name is taken from the Greek word "troglodytes" (from τρώγλη troglē "hole", and δῠ́ειν dyein, "creep"), meaning "hole-dweller", and refers to its habit of disappearing into cavities or crevices whilst hunting arthropods or to roost. The taxonomy of the genus Troglodytes is currently unresolved, as recent molecular studies have suggested that the genera Cistothorus and Thryorchilus are within the clade currently defined by Troglodytes.

GBIF citizen-science records
It is estimated from how often the Eurasian Wren is recorded against all the birds logged in Rotterdam [The Hague] (721 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
