Recently, this species was observed in several locations throughout Southwest China, including Ningming and Baise, Guangxi(2012, 2013), and Xichang, Sichuan(2013). These sightings are the first distribution record of this species in China's Mainland, suggesting that the white-browed crake is following a natural species dispersal northward into China's Mainland from Southeast Asia.展开更多
