Bird Thought To Be Extinct Resurfaces In Myanmar

Jerdon’s Babbler

Excerpt from techtimes.com

Jerdon’s Babbler is a species of bird that was believed to be extinct

until this species unexpectedly resurfaced in Myanmar. This brown and

white bird is roughly the size of a house sparrow.

The bird was last witnessed in Myanmar during July 1941, close to the

Sittaung River just outside Myitkyo. The species was re-discovered on a

former agricultural station, on May 30, 2014.

Ornithologists heard the unusual call of the bird, which was recorded

on audio equipment. When the sound was played back, one of the

long-lost birds came into view. A two-day-long search revealed several

of the birds living in the region. Researchers were able to obtain

several detailed photographs of the animals and gathered blood samples

from a few of the creatures.

Jerdon’s babblers were once found throughout the region and were

plentiful 100 years ago. However, human development, including

agriculture and settlements, destroyed much of the grassy plains on

which the species depended to live, destroying populations.

“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,” Colin Poole, director of the Singapore chapter

of the Wildlife Conservation Society, said.

The species was first discovered in January 1862 by T. C. Jerdon, a naturalist in Britain.

DNA analysis gathered from the birds will be examined, in order to

see whether the animals are a true species apart from other animals. If

this is the case, Jerdon’s babbler would be considered limited to

Myanmar, and highly threatened due to habitat loss. That nation has more

species of birds than any other country in the region. As naturalists

continue to find additional varieties of the animals, that number is

expected to grow.

“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,” Frank Rheindt, a member of the field team who found the

birds, stated in a press release.

Currently, without genetic information, the bird is classified as a

sub-species, one of three found in South Asia’s Indus, Ayeyarwady and

Bhramaputra River basins.

“Future work is needed to identify remaining pockets of natural

grassland and develop systems for local communities to conserve and

benefit from them,” Poole said.

Re-discovery of the Jerdon’s babbler was profiled in BirdingAsia, a publication of the Oriental Bird Club.
