Grey-crowned Warbler © oiseaux.net

Seicercus burkii (Sibley and Monroe 1990, 1993) has been split into Green-crowned Warbler (Phylloscopus burkii), Bianchi's Warbler (Phylloscopus valentini), Whistler's Warbler (Phylloscopus whistleri), Alstrom's Warbler (Phylloscopus soror) and Grey-crowned Warbler (Phylloscopus tephrocephalus) following Alström and Olsson (1999) and Martens's Warbler (Phylloscopus omeiensis) following Martens et al. (1999). Use of the common name 'Green-crowned Warbler', follows Rasmussen and Anderton (2005) and Reindt (2006).

Formerly treated as conspecific with Green-crowned Warbler (Phylloscopus burkii), Whistler's Warbler (Phylloscopus whistleri) and Bianchi's Warbler (Phylloscopus valentini), and included also the populations recently described as Martens's Warbler (Phylloscopus omeiensis) and Alstrom's Warbler (Phylloscopus soror). All of these, however, exhibit constant differences in morphology, vocalizations and mitochondrial DNA, and up to four are syntopic (mainly or completely segregated altitudinally). Mitochondrial DNA also suggests that present species and Green-crowned Warbler (Phylloscopus burkii) are more closely related to White-spectacled Warbler (Phylloscopus intermedius) and Grey-cheeked Warbler (Phylloscopus poliogenys) than to the four other aforementioned species. Populations from western and northern portions of range may constitute separate subspecies. Formerly recognized subspecies distinctus appears to be synonymous with topotypical tephrocephalus.
