Russell's viper (Daboia russelii) is a species of highly venomous snake in the family Viperidae. The species is native to South Asia. It was described in 1797 by George Shaw and Frederick Polydore Nodder. It is named after Patrick Russell. Known for its extremely painful bite, it is considered one of the "Big Four" venomous snake species in the region.
Coluber russelii was the name proposed by George Shaw who described the species in 1797 based on a specimen presented to the British Museum by Patrick Russell. Russell described the species in 1796 and confirmed its highly venomous nature by experimenting on chickens and dogs. He added that the native people called it katuka retula poda.
Analysis of morphological and mitochondrial DNA data shows that the eastern subspecies of Russell's viper should be considered a separate species, Daboia siamensis. A number of other subspecies may be encountered in literature. including: Wikipedia →

No species of the same family or order lives in Chandigarh, so these are its closest relatives here: other reptiles.
Possible
About 30% of wildlife watchers report a Russell's Viper sighting in Chandigarh on a given day, based on 5 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
October
In that month about 60% of wildlife watchers report a Russell's Viper in Chandigarh on a given day, against under 5% in February, April–June and August, the lowest months. That is one of Chandigarh's driest months, with about 10 mm of rain against 280 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Russell's Viper sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 9 cities where we can rate Russell's Viper sightings, Chandigarh has the highest daily chance: about 30%. Next come Coimbatore (India, about 30%) and Pune (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Russell's Viper is recorded against all the reptiles logged in Chandigarh (5 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.
