Black-backed Swamphen	Thai race viridis moved to Grey-headed Swamphen due to taxonomic uncertainty. The taxonomic status of populations in South-East Asia [treated as subspecies viridis] is complex and poorly understood (Sangster, 1998). It is a variable form intermediate between poliocephalus and indicus resembling the former in the color of the head and neck and the latter in other plumage (Taylor, 1998). They are individually variable in regards to mantle color and the degree of grey on the sides of the head (Wells, 1999). Traditionally associated with the indicus group (i.e. Roselaar in Cramp et al, 1980; Ripley, 1977; Sangster, 1998, Garcia-R. and Trewick, 2015), but many individuals are inseparable in the field from poliocephalus and most more closely resemble poliocephalus than indicus. Thus, assignment to indicus would seem arbitrary based merely on phenotypic characteristics. No specimens from southeast Asia were included in the recent genetic study of this group (Garcia-R. and Trewick, 2015). Tentatively treated as a subspecies of poliocephalus pending more definitive studies.
Crow-billed Drongo	Spelling of scientific name corrected to *Dicrurus annectens, from D. annectans. Original spelling annectans* is an incorrectly spelt Latin word and must be emended. Dickinson & Christidis, 2014, HBW.

The original spelling with one "l" is an incorrect spelling of a Latin word intended to mean "hooded" as per the French vernacular name in the original description "Orthotome Chaperonné". Dickinson & Christidis 2014, HBW.
Thick-billed Warbler	Scientific name changed to *Arundinax aedon* from Iduna aedon. Thick-billed Warbler is a divergent and monotypic associate of the Iduna reed warblers (Fregin et al. 2009, Arbabi et al. 2014). Genus Arundinax has priority over previously used Phragmaticola (H&M 4, HBW).
Rufous-backed Sibia	Spelling of scientific name corrected to *Heterophasia annectens, from H. annectans. Original spelling annectans* is an incorrectly spelt Latin word and must be emended. Dickinson & Christidis, 2014, HBW.
