The sedge warbler (Acrocephalus schoenobaenus) is an Old World warbler in the genus Acrocephalus. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium.

The male's song is composed of random chattering phrases and can include mimicry of other species. The sedge warbler is mostly insectivorous.
The sedge warbler was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Motacilla schoenobaenus. The species is now placed in the genus Acrocephalus that was introduced in 1811 by Johann Andreas Naumann and his son Johann Friedrich Naumann. British ornithologists did not distinguish the species from the common reed warbler until the 18th century. The genus name Acrocephalus is from Ancient Greek akros, "highest", and kephale, "head". It is possible that the Naumanns thought akros meant "sharp-pointed". The specific schoenobaenus is from Ancient Greek skhoinos, "reed", and baino, "to tread".

Possible
About 30% of wildlife watchers report a Sedge Warbler sighting in Kiskunság National Park on a given day, based on 343 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 69th most-seen of the 222 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 60% of wildlife watchers report a Sedge Warbler in Kiskunság National Park on a given day, against under 5% in March and November, the lowest months. That is one of Kiskunság National Park's wettest months, with about 75 mm of rain against 35 mm in April.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sedge Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 20
Of the 20 parks where we can rate Sedge Warbler sightings, Kiskunság National Park ranks 5th at about 30%. The best odds are in Biebrza National Park (Poland, about 50%), Fertő-Hanság National Park (Hungary, about 40%) and Białowieża National Park (Poland, about 40%). All parks ranked.
Same genus: Acrocephalus
The closest relatives of the Sedge Warbler that you can see in Kiskunság National Park (genus Acrocephalus, Reed Warblers) are Eurasian Reed-Warbler (about 30%), Great Reed-Warbler (about 30%) and Marsh Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sedge Warbler is recorded against all the birds logged in Kiskunság National Park (343 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.
