The barred warbler (Curruca nisoria) is a species of bird in the warbler family Sylviidae which breeds across temperate regions of central and eastern Europe and western and central Asia. This passerine bird is strongly migratory, and winters in tropical eastern Africa.
It is the largest Curruca warbler, 15.5–17 cm in length and weighing 22–36 g, mainly grey above and whitish below. Adult males are dark grey above with white tips on the wing coverts and tail feathers, and heavily barred below. The female is similar but slightly paler and has only light barring. Young birds are buffy grey-brown above, pale buff below, and have very little barring, with few obvious distinctive features; they can easily be confused with garden warblers, differing in the slight barring on the tail coverts and the pale fringes on the wing feathers, and their slightly larger size. The eye has a yellow iris in adults, dark in immatures; the bill is blackish with a paler base, and the legs stout, grey-brown.
Within the genus Curruca it is highly distinctive; the barred underside is shared only with the Cyprus warbler, which has black barring and an entirely different overall colour pattern. The... Wikipedia →

Rare
Under 5% of wildlife watchers report a Barred Warbler sighting in Dubai on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 89th most-seen of the 170 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 a Barred Warbler in Dubai on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Barred Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 16
Of the 16 cities where we can rate Barred Warbler sightings, Dubai ranks 11th at under 5%. The best odds are in Abu Dhabi (United Arab Emirates, about 10%), Jerusalem (Israel, about 10%) and Doha (Qatar, about 10%).
GBIF citizen-science records
It is estimated from how often the Barred Warbler is recorded against all the birds logged in Dubai (30 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.
