Rare
Under 5% of wildlife watchers report a Black-headed Collared Snake sighting in Singapore on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 61st 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 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-headed Collared Snake in Singapore on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-headed Collared Snake 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 Black-headed Collared Snake sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Colubridae
The closest relatives of the Black-headed Collared Snake that you can see in Singapore (family Colubridae, Colubrid Snakes) are Oriental Whipsnake (about 20%), Common Bronze-back (about 20%) and Paradise Flying Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-headed Collared Snake is recorded against all the reptiles logged in Singapore (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.
