The buff striped keelback (Amphiesma stolatum) is a species of nonvenomous colubrid snake found across Asia. It is a typically non-aggressive snake that feeds on frogs and toads. It belongs to the subfamily Natricinae, and is closely related to water snakes and grass snakes. It resembles an Asian version of the American garter snake. It is quite a common snake but is rarely seen.
Based on morphological characters including hemipenial morphology, dentition, and external scalation, in 1960 the genus Natrix sensu lato was divided into several genera, revalidating the genus Amphiesma with the type species A. stolatum.
A small, slender snake, the buff striped keelback is generally olive-brown to gray in colour. The head and the body are of the same colour. The body of the buff striped keelback is short, and it has a long slender tail which is almost a quarter of its length. Two yellow stripes along the length and to the sides of the spine are the distinctive feature of this snake. These stripes are diffuse at the head and are especially bright on the second half of its body.
The keelback has irregular blackish crossbars on the body. Near the... Wikipedia →

Possible
About 30% of wildlife watchers report a Buff Striped Keelback sighting in Thrissur on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 8 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Buff Striped Keelback in Thrissur on a given day, against under 5% in March–May and December–January, the lowest months. That is one of Thrissur's wettest months, with about 320 mm of rain against 10 mm in January.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Buff Striped Keelback 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 11 cities where we can rate Buff Striped Keelback sightings, Thrissur ranks 4th at about 30%, level with the leaders once rounded. The best odds are in Kalyan-Dombivli (India, about 30%), Guwahati (India, about 30%) and Dehradun (India, about 30%).

GBIF citizen-science records
It is estimated from how often the Buff Striped Keelback is recorded against all the reptiles logged in Thrissur (7 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.
