The Basra reed warbler (Acrocephalus griseldis) is a "warbler" of the genus Acrocephalus. It is a near-endemic breeder in the Tigris–Euphrates river system in southwestern Iran, eastern and southern Iraq, and Kuwait, though it has also recently colonised wetlands in Israel. It breeds in extensive beds of papyrus and reeds. It is easily mistaken for the great reed warbler but is a bit smaller, has whiter underparts and has a narrower, longer and more pointed bill. It is migratory, wintering in East Africa. It is a very rare vagrant in Europe. The call is a gruff chaar, deeper than that of a common reed warbler.
It is found in aquatic vegetation in or around shallow, fresh or brackish water, still or flowing, mainly in dense reedbeds. It is found in thickets and bushland when migrating or wintering. In 2007, the species was discovered as a breeding bird in northern Israel.
Due to the drainage of the Mesopotamian marshes throughout the 1980s and the 1990s, and the subsequent near destruction of its native habitat, the Basra reed warbler is considered an endangered species. Wikipedia →

With luck
About 10% of wildlife watchers report a Basra Reed Warbler sighting in Kuwait City on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 91st most-seen of the 157 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Basra Reed Warbler in Kuwait City on a given day, against under 5% in May to March, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Basra Reed 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.
Only Kuwait City, in our data

GBIF citizen-science records
It is estimated from how often the Basra Reed Warbler is recorded against all the birds logged in Kuwait City (20 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.
