The silver-breasted broadbill (Serilophus lunatus) is a species of bird in the broadbill family, Eurylaimidae that is found in parts of Southeast Asia. There are seven currently recognised subspecies; the other species in the genus Serilophus, the grey-lored broadbill, was also previously treated as being a subspecies of this species.
The silver-breasted broadbill was formally described in 1834 by the English ornithologist John Gould. He placed it in the genus Eurylaimus and coined the binomial name Eurylaimus lunatus. The specific epithet is Latin meaning "crescent-shaped" of "sickle-shaped", from Latin luna meaning "moon". Gould specified the type locality as the neighbourhood of Rangoon (now Yangon) in Myanmar but the locality was subsequently restricted to the hills in the region of Bago, which lie to the north of Yangon.
The silver-breasted broadbill is now one of two species placed in the genus Serilophus that was introduced in 1837 by William Swainson. The other species in Serilophus, the grey-lored broadbill, was formerly considered to be a subspecies of the silver-breasted broadbill.

Rare
Under 5% of wildlife watchers report a Silver-breasted Broadbill sighting in Doi Inthanon National Park on a given day, based on 137 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 192nd most-seen of the 367 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and March
In those months about 10% of wildlife watchers report a Silver-breasted Broadbill in Doi Inthanon National Park on a given day, against under 5% in April to January, the lowest months. Those are among Doi Inthanon National Park's driest months, with about 25 mm of rain a month against 340 mm in August.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Silver-breasted Broadbill sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
3rd of 7
Of the 7 parks where we can rate Silver-breasted Broadbill sightings, Doi Inthanon National Park ranks 3rd at under 5%. The best odds are in Kaeng Krachan National Park (Thailand, about 20%) and Manas National Park (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Silver-breasted Broadbill is recorded against all the birds logged in Doi Inthanon National Park (137 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.
