Rare
Under 5% of wildlife watchers report a Black Cross-barred Kukri Snake sighting in Hong Kong on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 39th 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.
June and September
In those months about 10% of wildlife watchers report a Black Cross-barred Kukri Snake in Hong Kong on a given day, against under 5% in July–August and October–May, the lowest months. Those are among Hong Kong's wettest months, with about 220 mm of rain a month against 25 mm in December.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Black Cross-barred Kukri Snake sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Black Cross-barred Kukri Snake sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black Cross-barred Kukri Snake is recorded against all the reptiles logged in Hong Kong (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.
