The green broadbill (Calyptomena viridis) also known as the Asian green broadbill or the lesser green broadbill is a small bird in the family Calyptomenidae. It was formerly classified in the family Eurylaimidae, a group of closely related birds that share the name "broadbill".
There are three subspecies recognized: Calyptomena viridis viridis Raffles, 1822 - the Malay Peninsula, extirpated from Singapore Calyptomena viridis gloriosa Deignan, 1947 - Sumatra, Borneo, Nias, the Lingga Islands, and the Natuna Islands
Calyptomena viridis siberu Chasen & Kloss, 1926 - Mentawai Islands Prior to revisions by the International Ornithological Congress in 2022, the mainland subspecies went by the name caudacuta, while viridis referred to the Greater Sundaic subspecies. Based on several previous studies finding problems with this nomenclature, the International Ornithological Congress replaced caudacuta with viridis, while gloriosa replaced the former viridis.
The green broadbill is distributed in broadleaved evergreen forests of Borneo, Sumatra, and the Malay Peninsula where it frequents lowland and lower montane rainforest. The... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Green Broadbill is recorded against all the birds logged in Khao Sok National Park (31 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.
