Range Description

Oriolus mellianus is recorded in summer from south-central Sichuan, southern Guizhou, northern Guangxi and northern Guangdong, China (BirdLife International 2001). Despite a massive increase in observer coverage of forest sites in these and adjacent areas and much higher levels of reporting than in the 1990s, no new populations have been found and populations at known sites have all declined since c.2001, such that a serious decline is apparent (R. Lewthwaite in litt. 2012). Whereas surveys in 1988 found it to be locally common in south-central Sichuan, with a notable record of a flock of 40 birds, the highest count there subsequently is 10 in June 2006 (COS 2007). One at Maolan, southern Guizhou in May 1984 remains the only summer record for the province. In Guangxi, there are no records since August 1998 when four individuals were found at Maoershan (Kadoorie Farm and Botanic Garden); the absence of records at Dayao Shan, a historically important site, is also striking. In Guangdong, peak day counts at Ba Bao Shan/Nanling NNR were 20 in 1998 and 10 (including nine males) in 2001; but the highest count since then is four in May 2007 (COS 2008, R. Lewthwaite in litt. 2012). There are also records in China of single birds on passage at Nankun Shan, southern Guangdong in August 1995, Weining, western Guizhou in September 1984 and Ningming, south-western Guanxi in October 1958; one at Ximeng, southern Yunnan on an unknown date was presumably also on passage (R. Lewthwaite in litt. 2012). It is a non-breeding visitor to southern Thailand and Cambodia. Records of wintering birds in Thailand have declined through the 1990s, although survey effort in the far north of the country has been limited. An increase in ornithological surveys in Cambodia has yielded recent records from the Cardamom Mountains and Bokor (Pilgrim and Pierce 2006). Most winter records have involved males, and it may prove to be the case that females winter further north, and possibly occur in southern Myanmar (Pilgrim and Pierce 2006). Given the limited area of remaining habitat, it is likely to have a very small and declining population.
