The Yellow-Breasted Bunting is an endangered bird species that may very well be wiped out entirely because folks in Guangdong think that it 1) makes them into sex gods and 2) is freaking delicious.
Reason #1 is an uncomfortably common occurrence in China; woe to the rhinos, elephants, buntings, et al., who are sacrificed for the demand of Traditional Chinese Dick-Medicine. Chinese demand, especially in Guangdong, is on the verge of annihilating the yellow-breasted bunting, as South China Morning Post reports:
Experts are unsure exactly how many are left, but BirdLife International, a conservation group headquartered in Britain, has cited one study published in 2009 that estimates there were no more than about 10,000 migrating in China every season. […]
“The very rapid recent population decline in the yellow-breasted bunting is believed to be primarily driven by trapping at migration and, in particular, wintering sites in southern China and Southeast Asia,” said Andy Symes, global species officer with BirdLife. […]
The Guangzhou Daily reported last week yellow-breasted bunting was still sold discreetly at certain restaurants and markets in Dongguan, at an average price of 30 to 45 yuan.
