‘EXTINCT’ Myanmar Babbler SPOTTED AFTER 73 YEARS
The Myanmar Jerdon’s babbler (Chrysomma altirostre altirostre) had not been seen in Myanmar since July 1941, where it was last found in grasslands near the town of Myitkyo, Bago Region near the Sittaung River.

A bird thought to have been extinct has been spotted by scientists alive and well in Myanmar, 74 years after the last sighting.
The team found the bird while surveying a site around an abandoned agricultural station that still contained some grassland habitat. After hearing the bird’s distinct call, the scientists played back a recording and were rewarded with the sighting of an adult Jerdon’s babbler. Over the next 48 hours, the team repeatedly found Jerdon’s babblers at several locations in the immediate vicinity and managed to obtain blood samples and high-quality photographs.
At the beginning of the 20th century, the species was common in the vast natural grassland that once covered the Ayeyarwady and Sittaung flood plains around Yangon. Since then, agriculture and communities have gradually replaced most of these grasslands as the area has developed.
The Jerdon’s Babbler in Myanmar is one of three subspecies found in the Indus, Bhramaputra, and Ayeyarwady River basins in South Asia. All show subtle differences and may yet prove to be distinctive species.
“The degradation of these vast grasslands had led many to consider this subspecies of Jerdon’s Babbler extinct,” said Colin Poole, Director of WCS’s Regional Conservation Hub in Singapore.
“This discovery not only proves that the species still exists in Myanmar but that the habitat can still be found as well. Future work is needed to identify remaining pockets of natural grassland and develop systems for local communities to conserve and benefit from them.”
