NAT. HIST. BULL. SIAM Soc. 49: 117-119，2001 A Record of Oriolus traillii nigellicauda from Thailand 百leMaroon Oriole is represented in百lailandby the apparently resident subspecies， O. traillii traillii，w hich breeds in mountains of the North，m ainly at elevations of over 1000 m (LEKAGUL AND ROUND，1 991). Occasional wintering Maroon Orioles have also been recorded from Khao Yai National Park (DICKINSON AND TUBB，1 964) and at Khao Soi Dao，C hanthaburi Province，S E百四land(LEKAGUL AND ROUND，op . citふ百leonly specimen of aw intering bird，a m ale，te stes inactive，w as taken at Khao Soi Dao Tai，in side the present-day Khao Soi Dao Wildlife Sanctuary，o n 2D ecember 1972 by Nivesh Nadee at elevationof 850 m above sea level where it was shot from af lowering tree. 組 An illus甘ationbased on this specimen (TISτR 53-3313; field number KT2622) was shown in bo白 LEKAGULAND CRONIN (1974)組 dLEKAGUL AND ROUND (1991)，a nd forms the basis for the supposed occuencein Thailand of O. traillii robinsoni，w hich 町 br< dsin the mountains of S.

Although the specimen was not brought to Tring for direct comparison， from memory it appeared to be an almost perfect match for males of O. t. nigellicauda， specimens of which were available for scrutiny. Ap hotograph of the Khao Soi Dao specimen was sent to Craig Robson in 2000 who agreed with its diagnosis as O. t. nigellicauda， compingit with five adult males from East Tonkin and North Annam (C. Robson，in ぽ litt.). Description.
