The orange-bellied flowerpecker (Dicaeum trigonostigma) is a species of bird in the family Dicaeidae. It is found in Bangladesh, Brunei, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, and Thailand.

With luck
About 10% of wildlife watchers report an Orange-bellied Flowerpecker sighting in Singapore on a given day, based on 1,259 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 298 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report an Orange-bellied Flowerpecker in Singapore on a given day, against about 10% in June to April, the lowest months.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Orange-bellied Flowerpecker 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.
4th of 7
Of the 7 cities where we can rate Orange-bellied Flowerpecker sightings, Singapore ranks 4th at about 10%. The best odds are in Davao City (Philippines, about 30%), Kuching (Malaysia, about 30%) and Kuala Lumpur (Malaysia, about 20%).
GBIF citizen-science records
It is estimated from how often the Orange-bellied Flowerpecker is recorded against all the birds logged in Singapore (1,259 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.
