The Green Broadbill, Calyptomena viridis, is a small, approximately 17cm long, brilliant green-plumaged bird with a black ear patch, wide gape bill, rounded head, short tail and three black bars on wings. The bill itself is very weak and almost hidden by the crest above it. Both sexes are similar. The female is duller and has no black markings on its ear patch and wing coverts.

The Green Broadbill is distributed in broadleaved evergreen forests of Borneo, Sumatra and Malay Peninsula.

It feeds largely on soft figs. The broadbill's feeding habits helps to distribute the seeds of the fig around the forest floor. The female usually lays between two to three whitish eggs, and the young fledge after twenty-two to twenty-three days.

Due to continuing habitat loss, the Green Broadbill is evaluated as Near Threatened on the IUCN Red List of Threatened Species.
