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.

Possible
About 20% of wildlife watchers report a Eurasian Wren sighting in Kiskunság National Park on a given day, based on 226 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 86th most-seen of the 222 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November and December
In those months about 60% of wildlife watchers report a Eurasian Wren in Kiskunság National Park on a given day, against under 5% in May to September, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eurasian Wren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
24th of 33
Of the 33 parks where we can rate Eurasian Wren sightings, Kiskunság National Park ranks 24th at about 20%. The best odds are in Białowieża National Park (Poland, about 60%), Cairngorms National Park (United Kingdom, about 60%) and Tatra National Park (Slovakia, about 50%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Eurasian Wren that you can see in Kiskunság National Park (order Passeriformes, Perching Birds) are Hooded Crow (about 80%), European Starling (about 70%) and Rook (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eurasian Wren is recorded against all the birds logged in Kiskunság National Park (226 verified sightings from 2019 to 2026), 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.
