The Javan kingfisher (Halcyon cyanoventris), sometimes called the blue-bellied kingfisher or Java kingfisher, is a medium-sized kingfisher (subfamily Halcyoninae) endemic to the Indonesian islands of Java and Bali. The brightly-colored Javan kingfisher has the large head and bill typical of kingfishers, although the species is less suited for aquatic hunting than many of its relatives and catches much of its prey on land or near the water's edge. The highly territorial bird lays its round white eggs in burrows excavated from earthen walls and riverbanks.
The Javan kingfisher was first described in 1818 by the French ornithologist Louis Pierre Vieillot, who gave it the scientific name Alcedo cyanoventris. In 1821, William Swainson created the genus Halcyon for some of kingfishers — primarily those with stronger, thicker, more rounded beaks. The bird is today listed under the genus Halcyon, referring to the "Halcyon" bird of Greek legend, which contains 11 species of large, heavy-billed kingfishers. Halcyon kingfishers generally prefer woodlands and primarily consume small terrestrial animals rather than fish. H. cyanoventris forms a superspecies with the white-throated... Wikipedia →

Possible
About 30% of wildlife watchers report a Javan Kingfisher sighting in Yogyakarta on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 42 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 50% of wildlife watchers report a Javan Kingfisher in Yogyakarta on a given day, against under 5% in January and August–November, the lowest months. That is one of Yogyakarta's driest months, with about 95 mm of rain against 350 mm in January.
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.
Yes
Of the 3 cities where we can rate Javan Kingfisher sightings, Yogyakarta has the highest daily chance: about 30%. Next come Jakarta (Indonesia, about 20%) and Bandung (Indonesia, about 20%).
Same family: Alcedinidae
The closest relatives of the Javan Kingfisher that you can see in Yogyakarta (family Alcedinidae, Kingfishers) are Collared Kingfisher (about 30%) and Blue-eared Kingfisher (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Javan Kingfisher is recorded against all the birds logged in Yogyakarta (12 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.
