Rare
Under 5% of wildlife watchers report a Big Tree Skink sighting in Singapore on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 46th most-seen of the 64 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.
April, October and December
In those months about 10% of wildlife watchers report a Big Tree Skink in Singapore on a given day, against under 5% in January–March, May–September and November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Big Tree Skink sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Big Tree Skink sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Scincidae
The closest relatives of the Big Tree Skink that you can see in Singapore (family Scincidae, Skinks) are Many-lined Sun-skink (about 30%), Banded Lipinia (about 10%) and Bowring’s Supple Skink (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Big Tree Skink is recorded against all the reptiles logged in Singapore (27 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.
