Rare
Under 5% of wildlife watchers report a Dwarf Crowned Snake sighting in Brisbane on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 41st most-seen of the 43 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 Dwarf Crowned Snake in Brisbane on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Dwarf Crowned Snake sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Dwarf Crowned Snake sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Cacophis
The closest relatives of the Dwarf Crowned Snake that you can see in Brisbane (genus Cacophis, Crowned Snakes) are Golden Crowned Snake (about 10%) and White-crowned Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dwarf Crowned Snake is recorded against all the reptiles logged in Brisbane (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.
