New 'bald' bird discovered

30-07-2009

An odd songbird with a bald head living in a rugged region in Laos has been discovered by scientists from the Wildlife Conservation Society (WCS) and the University of Melbourne, as part of a project funded and managed by the mining company MMG (Minerals and Metals Group).

The species has been named Bare-faced Bulbul Pycnonotus hualon because of the lack of feathers on its face and part of its head, it is the only example of a bald songbird in mainland Asia. It is the first new species of bulbul – a family of about 130 species – described in Asia in over 100 years. A description of the new species has been published in the July issue of Forktail, the journal of the Oriental Bird Club.

"This is exciting news and a great discovery", said Dr Lincoln Fishpool, BirdLife's Global Important Bird Areas Coordinator. "It highlights the importance of this region for birds and biodiversity."

The thrush-sized bird is greenish-olive with a light-colored breast, a distinctive featherless, pink face with bluish skin around the eye extending to the bill and a narrow line of hair-like feathers down the centre of the crown.

The bird seems to be primarily tree-dwelling and was found in an area of sparse forest on rugged limestone karsts – a little-visited habitat known for unusual wildlife discoveries.

It [the discovery] highlights the importance of this region for birds and biodiversity" —Dr Lincoln Fishpool, BirdLife

"Its apparent restriction to rather inhospitable habitat helps to explain why such an extraordinary bird with conspicuous habits and a distinctive call has remained unnoticed for so long", said Iain Woxvold of the University of Melbourne and lead author of the paper.      

Fortunately much of the bird's presumed habitat falls within legally protected areas in Laos. However, quarrying of limestone looms as a potential threat to wildlife in this area, along with habitat conversion for agriculture.

In 2002 in this same area, Rob Timmins of WCS described the Kha-nyou or Laotian Rock Rat Laonastes aenigmamus, a newly discovered species of rodent so unusual it represented the lone surviving member of an otherwise extinct genus.

This taxon will be assessed in due course by the BirdLife Taxonomic Working Group, BirdLife will then evaluate its extinction risk category for the IUCN Red List (for which BirdLife is the official Red List Authority).
