Possible
About 20% of wildlife watchers report a Günther's Vine Snake sighting in Eravikulam National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June, August and October
In those months about 30% of wildlife watchers report a Günther's Vine Snake in Eravikulam National Park on a given day, against under 5% in February and May, the lowest months. Those are among Eravikulam National Park's wettest months, with about 350 mm of rain a month against 25 mm in February.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Günther's Vine Snake sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Eravikulam National Park, in our data
Eravikulam National Park is the only park on Wallace's Line with enough records to rate Günther's Vine Snake sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Günther's Vine Snake is recorded against all the reptiles logged in Eravikulam National Park (25 verified sightings from 2019 to 2026), 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.
