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 →

Rare
Under 5% of wildlife watchers report a Javan Pond Heron sighting in Tangkoko Nature Reserve on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 100th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Javan Pond Heron in Tangkoko Nature Reserve on a given day, against under 5% in January to November, the lowest months.
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.
3rd of 5
Of the 5 parks where we can rate Javan Pond Heron sightings, Tangkoko Nature Reserve ranks 3rd at under 5%. The best odds are in Bali Barat National Park (Indonesia, about 40%) and Way Kambas National Park (Indonesia, about 30%).
Same family: Ardeidae
The closest relatives of the Javan Pond Heron that you can see in Tangkoko Nature Reserve (family Ardeidae, Herons, Egrets, and Bitterns) are Pacific Reef Heron (about 20%), Striated Heron (about 10%) and Nankeen Night-Heron (about 10%), 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 Tangkoko Nature Reserve (27 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.
