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 →

Possible
About 20% of wildlife watchers report a Javan Pond Heron sighting in Bangkok on a given day, based on 1,757 verified sightings from GBIF citizen-science data. It is the 47th most-seen of the 277 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May–June and August
In those months about 30% of wildlife watchers report a Javan Pond Heron in Bangkok on a given day, against under 5% in November and December, the lowest months. Those are among Bangkok's wettest months, with about 170 mm of rain a month against 10 mm in December.
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.
8th of 15
Of the 15 cities where we can rate Javan Pond Heron sightings, Bangkok ranks 8th at about 20%. The best odds are in Denpasar (Indonesia, about 60%), Jakarta (Indonesia, about 60%) and Makassar (Indonesia, about 50%).
GBIF citizen-science records
It is estimated from how often the Javan Pond Heron is recorded against all the birds logged in Bangkok (1,757 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.
