The moustached warbler (Acrocephalus melanopogon) is an Old World warbler in the genus Acrocephalus. It breeds in southern Europe and southern temperate Asia with a few breeding in north-west Africa. It is partially migratory. South-west European birds are resident, south-east European birds winter in the Mediterranean breeding range, and the Asiatic race migrates to Arabia, India and Pakistan.
The moustached warbler was formally described and illustrated in 1823 by the Dutch zoologist Coenraad Jacob Temminck based on a specimen collected near Rome in Italy. He coined the binomial name Sylvia melanopogon. The moustached warbler is now one of 42 warblers placed in the genus Acrocephalus that was introduced in 1811 by the German naturalist Johann Andreas Naumann and his son Johann Friedrich Naumann. The genus name combines the Ancient Greek ακρος/akros meaning "point" or "crest" with -κεφαλος/-kephalos meaning "-headed". The specific epithet melanopogon combines the Ancient Greek μελας/melas, μελανος/melanos meaning "black" with πωγων/pōgōn, πωγωνος/pōgōnos meaning "beard".

Rare
Under 5% of wildlife watchers report a Moustached Warbler sighting in New Delhi on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 218th most-seen of the 248 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Moustached Warbler in New Delhi 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 Moustached 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.
Among the best
Of the 10 cities where we can rate Moustached Warbler sightings, New Delhi ranks 9th at under 5%, level with the leaders once rounded. The best odds are in Yerevan (Armenia, under 5%), Kuwait City (Kuwait, under 5%) and Antalya (Turkey, under 5%).
GBIF citizen-science records
It is estimated from how often the Moustached Warbler is recorded against all the birds logged in New Delhi (12 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.
