The eastern Orphean warbler (Curruca crassirostris) is an Old World warbler of the genus Curruca. This species occurs in summer around the Mediterranean, through the Balkans via Turkey, the Caucasus and surrounding regions to Central Asia. It is migratory, wintering in sub-Saharan Africa.
At 15–16 cm length—somewhat larger than a blackcap—this is one of the largest species of typical warblers. The adult males have a plain grey back. The bill is long and pointed and the legs black. The male has a dark grey head, black eye mask, and white throat. The iris is white. Females and immatures have a paler head and reddish underparts; their grey back has a brownish tinge. The iris is dark in young birds. It is difficult to visually distinguish from the Western Orphean warbler.
The song is a series of warbling liroo-liroo and scolding notes. Its song is more varied than that of the western Orphean warbler, approaching the Nightingale in richness. These small passerine birds are found in open deciduous woodland. 4–6 eggs are laid in a nest in a bush or tree. Like most "warblers", the eastern Orphean warbler is a nectarivore.

Rare
Under 5% of wildlife watchers report an Eastern Orphean Warbler sighting in Keoladeo National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 225th most-seen of the 278 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Eastern Orphean Warbler in Keoladeo National Park on a given day, so our monthly data shows no clear season.
Only Keoladeo National Park, in our data
Keoladeo National Park is the only park on Wallace's Line with enough records to rate Eastern Orphean Warbler sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eastern Orphean Warbler is recorded against all the birds logged in Keoladeo National Park (19 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.
