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 Royal Manas National Park on a given day, based on 57 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 211th most-seen of the 388 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–March and November–December
In those months about 10% of wildlife watchers report a Silver-breasted Broadbill in Royal Manas National Park on a given day, against under 5% in January, April–July and October, the lowest months. Those are among Royal Manas National Park's driest months, with about 50 mm of rain a month against 930 mm in July. August and September have too few records to rate.
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.
4th of 7
Of the 7 parks where we can rate Silver-breasted Broadbill sightings, Royal Manas National Park ranks 4th at under 5%. The best odds are in Kaeng Krachan National Park (Thailand, about 20%), Manas National Park (India, about 20%) and Doi Inthanon National Park (Thailand, under 5%).
GBIF citizen-science records
It is estimated from how often the Silver-breasted Broadbill is recorded against all the birds logged in Royal Manas National Park (57 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.
