With luck
About 10% of wildlife watchers report a Boettger's dainty frog sighting in Addo Elephant National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Boettger's dainty frog in Addo Elephant National Park on a given day, against under 5% in April and July–January, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Boettger's dainty frog sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Addo Elephant National Park, in our data
Addo Elephant National Park is the only park on Wallace's Line with enough records to rate Boettger's dainty frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Boettger's dainty frog is recorded against all the amphibians logged in Addo Elephant National Park (6 verified sightings from 2019 to 2026), 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.
