Rare
Under 5% of wildlife watchers report a Linnaeus' Sipo sighting in San José on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 24 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January and June–July
In those months about 10% of wildlife watchers report a Linnaeus' Sipo in San José on a given day, against under 5% in February–May and August–December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Linnaeus' Sipo sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only San José, in our data
San José is the only city on Wallace's Line with enough records to rate Linnaeus' Sipo sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Colubridae
The closest relatives of the Linnaeus' Sipo that you can see in San José (family Colubridae, Colubrid Snakes) are Spotted Coffee Snake (about 10%), Hoffmann's Earth Snake (about 10%) and Green Rat Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Linnaeus' Sipo is recorded against all the reptiles logged in San José (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.
