Blyth's reed warbler (Acrocephalus dumetorum) is a species of reed warbler belonging to the family Acrocephalidae, which also includes the tree warblers. Blyth's reed warbler breeds across the Palearctic zoogeographical region and winters in South Asia. The species has been expanding its range westwards in Europe.
Blyth's reed warbler was first formally described in 1849 by the English zoologist Edward Blyth with its type locality given as India. It is classified in the reed warbler genus Acrocephalus which was formerly included in the polyphyletic family Sylviidae but is now included in the family Acrocephalidae.
Blyth's reed warbler is named in honour of Edward Blyth, its describer. The genus name Acrocephalus is from Ancient Greek akros, "highest", and kephale, "head". It is possible that Naumann and Naumann thought akros meant "sharp-pointed". The specific dumetorum is from Latin dumetum, "thicket".
Blyth's reed warbler is between 12 and 14 cm (4.7 and 5.5 in) in length and weighs between 8 and 16 g (0.28 and 0.56 oz). It is a slim warbler with relatively short wings and a long bill. The plumage is rather plain with few distinguishing... Wikipedia →

Possible
About 20% of wildlife watchers report a Blyth's Reed Warbler sighting in Kozhikode on a given day, based on 344 verified sightings from GBIF citizen-science data. It is the 37th most-seen of the 229 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January
In that month about 40% of wildlife watchers report a Blyth's Reed Warbler in Kozhikode on a given day, against under 5% in May to September, the lowest months. That is one of Kozhikode's driest months, with about 5 mm of rain against 390 mm in June.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Blyth's Reed Warbler sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
11th of 72
Of the 72 cities where we can rate Blyth's Reed Warbler sightings, Kozhikode ranks 11th at about 20%. The best odds are in Vasai-Virar (India, about 40%), Thrissur (India, about 30%) and Tamluk (India, about 30%).
GBIF citizen-science records
It is estimated from how often the Blyth's Reed Warbler is recorded against all the birds logged in Kozhikode (344 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.
