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 Khao Yai National Park on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 198th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Silver-breasted Broadbill in Khao Yai National Park on a given day, so our monthly data shows no clear season.
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.
6th of 7
Of the 7 parks where we can rate Silver-breasted Broadbill sightings, Khao Yai National Park ranks 6th 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%).
Same family: Eurylaimidae
The closest relatives of the Silver-breasted Broadbill that you can see in Khao Yai National Park (family Eurylaimidae, Asian and Grauer's Broadbills) are Long-tailed Broadbill (about 30%) and Banded Broadbill (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Silver-breasted Broadbill is recorded against all the birds logged in Khao Yai National Park (44 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.
