Xenodon merremii, also known commonly as Wagler's snake, is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is endemic to South America and is widespread in the eastern half of the continent.
Xenodon merremii occurs in Venezuela, Guyana, Suriname, French Guiana, Brazil, Bolivia, Paraguay, Uruguay, and northern Argentina. The preferred natural habitat of Xenodon merremii is open areas of savanna and shrubland, at elevations from sea level to 2,000 m (6,600 ft), but it is also common in disturbed habitats.
The specific name, merremii, is in honor of German herpetologist Blasius Merrem. Adults of Xenodon merremii are usually 1 m (39 in) or less in total length (tail included). Its color pattern is very variable. Some "red phase" specimens are a uniform reddish tan. Other specimens are pale brown dorsally, with broad dark-brown crossbands, which are edged with black, and are narrower or interrupted in the middle. The latter color pattern resembles that of the venomous snake Bothrops alternatus.

Possible
About 20% of wildlife watchers report a Wagler's Snake sighting in Cochabamba on a given day, based on 5 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May and December
In those months about 40% of wildlife watchers report a Wagler's Snake in Cochabamba on a given day, against under 5% in January–March and June–November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Wagler's Snake sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Cochabamba, in our data
Cochabamba is the only city on Wallace's Line with enough records to rate Wagler's 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 Wagler's Snake is recorded against all the reptiles logged in Cochabamba (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.
