The crested toad or double crested toad (Ingerophrynus biporcatus) is a species of toad in the family Bufonidae. It is endemic to Indonesia. Its natural habitats are subtropical or tropical moist lowland forests, rivers, plantations, rural gardens, and heavily degraded former forest.
It is threatened by habitat loss. Frost, Darrel; et al. (2006). "The Amphibian Tree of Life". Bulletin of the American Museum of Natural History. 297: 1–291. doi:10.1206/0003-0090(2006)297[0001:TATOL]2.0.CO;2. ISSN 0003-0090. S2CID 86140137. Wikipedia →

Possible
About 20% of wildlife watchers report a Crested Toad sighting in Jakarta on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 18 amphibians 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, April–May and October–November
In those months about 30% of wildlife watchers report a Crested Toad in Jakarta on a given day, against under 5% in January, March and August, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Crested Toad sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Jakarta, in our data
Jakarta is the only city on Wallace's Line with enough records to rate Crested Toad sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Bufonidae
The closest relatives of the Crested Toad that you can see in Jakarta (family Bufonidae, True Toads) are Common Indian Toad (about 80%) and River Toad (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Crested Toad is recorded against all the amphibians logged in Jakarta (33 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.
