Possible
About 20% of wildlife watchers report a Javan Kingfisher sighting in Bali Barat National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 63rd most-seen of the 173 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February and September
In those months about 40% of wildlife watchers report a Javan Kingfisher in Bali Barat National Park on a given day, against under 5% in January, March–July and October–November, the lowest months.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Javan Kingfisher sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Bali Barat National Park, in our data
Bali Barat National Park is the only park on Wallace's Line with enough records to rate Javan Kingfisher sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Alcedinidae

GBIF citizen-science records
It is estimated from how often the Javan Kingfisher is recorded against all the birds logged in Bali Barat 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.
