The bristled grassbird (Schoenicola striatus) is a small passerine bird in the genus Schoenicola. Also known as the bristled grass warbler, this species is endemic to the Indian subcontinent, where it is patchily distributed in Bangladesh, India, Nepal and Pakistan. These insectivorous birds skulk in dense and tall grasslands, often in marshy areas, habitats that are threatened by human activities. Formerly considered to be sedentary, the species may be migratory, moving south and east in the Indian peninsula during winter and returning to their breeding grounds in the northern plains south of the Himalayas.
This warbler is large and brownish with broad dark streaks to the feathers of the crown and back and can appear almost babbler-like in appearance (easily mistaken for common babbler). The tail is graduated with white tips to the feathers. The rachis of the tail feathers is dark and there are dark ribs to the feathers. The bill is strong. The tarsus is brown and the bill is black with the lower mandible tipped bluish grey. They have a buff supercilium (brow) and have a pale unmarked underside.
This species was included in the "Old World warbler" family Sylviidae... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bristled Grassbird sighting in Kolkata on a given day, based on 152 verified sightings from GBIF citizen-science data. It is the 135th most-seen of the 247 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 Bristled Grassbird in Kolkata on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Bristled Grassbird sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Bristled Grassbird sightings, Kolkata ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Coimbatore (India, under 5%).
Same family: Locustellidae
The closest relatives of the Bristled Grassbird that you can see in Kolkata (family Locustellidae, Grassbirds and Allies) are Striated Grassbird (about 10%) and Pallas's Grasshopper Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bristled Grassbird is recorded against all the birds logged in Kolkata (152 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.
