Savi's warbler (Locustella luscinioides) is a species of Old World warbler in the genus Locustella. It breeds in Europe and the western Palearctic. It is migratory, wintering in northern and sub-Saharan Africa. This small passerine bird is found in reed beds, usually with some bushes. Three to six eggs are laid in a nest in reeds. The adult has an unstreaked grey-brown back, whitish grey underparts and a lack of throat streaks, which is a distinction from the river warbler. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous. This is not a shy species, but can be difficult to see in the reeds except sometimes when singing.
The song is a monotonous mechanical insect-like reeling, often given at dusk. It is similar to the song of other species in the group, but is generally faster and deeper and bears a strong resemblance to that of Roesel's bush-cricket.
The common name of this bird recognises the Italian ornithologist Paolo Savi, the author of "Ornitologia Toscana" (1827–1831) and "Ornitologia Italiana" (1873–1876). In 1821, Savi was given specimens of an unstreaked, dark, rufous-brown warbler which... Wikipedia →

Possible
About 30% of wildlife watchers report a Savi's Warbler sighting in Biebrza National Park on a given day, based on 564 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 202 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
May and June
In those months about 50% of wildlife watchers report a Savi's Warbler in Biebrza National Park on a given day, against under 5% in March, the lowest month.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Savi's Warbler sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 9 parks where we can rate Savi's Warbler sightings, Biebrza National Park has the highest daily chance: about 30%. Next come Fertő-Hanság National Park (Hungary, about 30%) and Hortobágy National Park (Hungary, about 30%).
GBIF citizen-science records
It is estimated from how often the Savi's Warbler is recorded against all the birds logged in Biebrza National Park (564 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.
