英文摘要：

Several Black-crested Bulbul （Pycnonotus flaviventris） with red throats were observed and photographed in December 2010 and April 2011 in the Youjiang District （N23°54＇, E06°36＇, altitude 179 m） and Jingxi County（N22°59＇, E1 06°40＇, altitude 354 m） of Baise city, northwestern Guangxi, in southern China. These individuals belong to subspecies johnsoni, recorded previously in central and southeastern Thailand as well as the southern Indochina Region. This sighting provides a new record of the subspecies within China, warranting a discussion on the classification and distribution of Pycnonotus flaviventris.
