The sighting raised hopes that more "extinct" species will be rediscovered.
The Red-Faced Liocichla previously thought to be extinct was rediscovered by a group of British ornithologists on a bird-watching trip in the Nepalese forest, the last sighting is thought to have been 178 years ago.
"We were excited when we first spotted a pair of Red-Faced Liocichla in the forest. The sighting of the bird after more than a century and a half has raised hopes of finding more such species that have not been sighted for a very long time," said Hem Sagar Baral, one of the birdwatchers to the China Post.
"It is a very shy kind of bird and is mostly solitary, sometimes found in pairs and small flocks," Baral said. The bird was found 1,800 meters above sea level and often lives in the leaves of trees and bamboo.
In Nepal, 167 out of 878 bird species are currently endangered due to climate change, habitat loss and environmental degradation, according to a status assessment of Nepal's birds in March 2016.
