Babbler Rising: Bird thought to be Extinct Re-emerges in Neglected Area
• Jerdon’s babbler is re-discovered near abandoned agricultural research station by WCS-led scientific team in Myanmar • Last confirmed sighting took place in 1941• Bird once common to Myanmar’s formerly vast grasslands• Scientists from WCS, Nature and Wildlife Conservation Division - MOECAF, and National University of Singapore made discovery
Newswise — NEW YORK (MARCH 5, 2015) – A scientific team from WCS, Myanmar’s Nature and Wildlife Conservation Division – MOECAF, and National University of Singapore (NUS) has rediscovered a bird previously thought to be extinct.
Jerdon’s babbler (Chrysomma 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.
The rediscovery was described in the recently published issue of Birding Asia, the magazine of the Oriental Bird Club.
The team found the bird on 30 May 2014 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.
The small brown bird, about the size of a house sparrow, was initially described by British naturalist T. C. Jerdon in January 1862, who found it in grassy plains near Thayetmyo.
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.
Said Mr Colin Poole, Director of WCS’s Regional Conservation Hub in Singapore, “The degradation of these vast grasslands had led many to consider this subspecies of Jerdon’s Babbler extinct. 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.”
The Jerdon’s Babbler in Myanmar is currently considered as 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.
Further analysis of DNA samples taken from the bird will be studied at the Department of Biological Sciences at the NUS Faculty of Science, to determine if Jerdon’s babbler in Myanmar should be considered a full species. If so, the species would be exclusive to Myanmar and be of very high conservation concern because of its fragmented and threatened habitat.
Explained Assistant Professor Frank Rheindt of the Department, who was a key member of the field team and leader of the genetic analysis, “Our sound recordings indicate that there may be pronounced bioacoustic differences between the Myanmar subspecies and those further west, and genetic data may well confirm the distinctness of the Myanmar population.”
This work was carried out as part of a larger study to understand the genetics of Myanmar bird species and determine the true level of bird diversity found in the country. Already Myanmar has more species of bird than any other country in mainland Southeast Asia and this number is likely to increase as our understanding of birds in this long isolated country continues to grow.
WCS’s work in Myanmar which led to this discovery was supported by The Leona M. and Harry B. Helmsley Charitable Trust.
