The Oriental dollarbird (Eurystomus orientalis) is a bird of the roller family, so named because of the distinctive pale blue or white, coin-shaped spots on its wings. It can be found from Australia to Korea, Japan and India.
The Oriental dollarbird was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae under the binomial name Coracias orientalis. Linnaeus based his description on "Le Rollier des Indes" that had been described and illustrated by the French zoologist Mathurin Jacques Brisson in 1760. The type locality is the island of Java in Indonesia. The Oriental dollarbird is now placed in the genus Eurystomus that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot.
A molecular phylogenetic study published in 2018 found that the azure dollarbird (Eurystomus azureus) was nested in a clade containing subspecies of the Oriental dollarbird. Formerly, some authorities have also considered the broad-billed roller and the azure dollarbird to have been subspecies of the oriental dollarbird. The generic name derives from Ancient Greek eurustomos 'wide-mouthed' and the specific epithet is Latin... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dollarbird sighting in Springbrook National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 118th most-seen of the 136 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.
February and March
In those months about 10% of wildlife watchers report a Dollarbird in Springbrook National Park on a given day, against under 5% in April to January, the lowest months. Those are among Springbrook National Park's wettest months, with about 200 mm of rain a month against 45 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Dollarbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
25th of 35
Of the 35 parks where we can rate Dollarbird sightings, Springbrook National Park ranks 25th at under 5%. The best odds are in Kinabatangan Wildlife Sanctuary (Malaysia, about 70%), Cat Tien National Park (Vietnam, about 60%) and Raja Ampat (Indonesia, about 40%). All parks ranked.
Same order: Coraciiformes
The closest relatives of the Dollarbird that you can see in Springbrook National Park (order Coraciiformes, Rollers, Kingfishers, and Allies) are Laughing Kookaburra (about 60%), Forest Kingfisher (about 10%) and Rainbow Bee-eater (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dollarbird is recorded against all the birds logged in Springbrook National Park (10 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.
