Black-throated Robin Rediscovered in China

The Black-throated Robin (Luscinia obscura ), also referred to as the Black-throated Blue Robin, or simply the Blackthroat, is a species in the Muscicapidae family of small passerine birds found mainly in the Old World – Europe, Asia and Africa. Primarily due to decimation of its preferred habitat of bamboo thickets and high altitude coniferous forest, this elusive little bird has become quite a rare sight in recent decades. So when a team of Swedish and Chinese researchers discovered a community of breeding Blackthroats in the Qinling Mountains of north-central China’s Shaanxi province, it was a newsworthy event.

With their distinctive song consisting of short, sharp, varied strophes including harsh notes and whistles, seven singing males were counted in Foping Nature Reserve, with another seven observed in the Changqing National Nature Reserve. Being the more vocal of the sexes, males are easier to find, and it is considered to be almost certain that each male has a mate. The majority of the birds were seen in bamboo thickets and coniferous-broadleaf forests at an altitude of around 2400 to 2500 meters above sea level. Recordings have been made of the Blackthroat’s song, which will made identification easier in the future.

Resembling a European Robin Erithacus rubecula in size and general shape, the Blackthroat male has a jet-black throat and breast, and while it is believed that the female has a light-brown throat and breast, this has not been confirmed. They were first recorded in the late 19th century, and between the time of first being observed and into the early 20th century, ten of these birds were collected during their breeding season of May to August, in two different localities in China’s Shaanxi and Gansu provinces. Subsequent Blackthoat sightings include unconfirmed records from China’s Yunnan and Sichuan provinces, as well as a few birds spotted in captivity at markets. The most recent reported sighting of a Blackthroat was at the Sichuan University campus in May 2011, with reports of a Blackthroat being captured in Thailand during the winter months, which is a possible migration destination or stop-over point.
