The Javan pond heron (Ardeola speciosa) is a wading bird of the heron family, found in shallow fresh and salt-water wetlands in Southeast Asia. Its diet comprises insects, fish, and crabs. The Javan pond heron is typically 45 cm long with white wings, a yellow bill with a black tip, yellow eyes and legs. Its overall colour is orange, slaty and white during mating season, and brown and flecked with white out of the mating season. The non-breeding plumage is similar to that of the Chinese and Indian pond herons and is virtually indistinguishable in the field. It breeds from June to September. It is migratory.
Widespread throughout its large range, the Javan pond heron is evaluated as Least Concern on the IUCN Red List of Threatened Species. BirdLife Species Factsheet Wikipedia →

Likely
About 60% of wildlife watchers report a Javan Pond Heron sighting in Jakarta on a given day, based on 746 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
June and August–September
In those months about 70% of wildlife watchers report a Javan Pond Heron in Jakarta on a given day, against about 40% in January and March–April, the lowest months. Those are among Jakarta's driest months, with about 75 mm of rain a month against 370 mm in February.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Javan Pond Heron sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 15 cities where we can rate Javan Pond Heron sightings, Jakarta ranks 2nd at about 60%, level with the leaders once rounded. The best odds are in Denpasar (Indonesia, about 60%).
Same family: Ardeidae
The closest relatives of the Javan Pond Heron that you can see in Jakarta (family Ardeidae, Herons, Egrets, and Bitterns) are Striated Heron (about 40%), Little Egret (about 30%) and Black-crowned Night Heron (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Javan Pond Heron is recorded against all the birds logged in Jakarta (746 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.
