| opmerkingen | Dit eerder als Moltoni's Baardgrasmus aanvaarde geval is in herroulatie gegaan op basis van nieuwe informatie met betrekking tot de roep (andere taxa kunnen ook een rateltje laten horen). Na herroulatie niet aanvaard als Moltoni's Baardgrasmus. Wel aanvaard als Baardgrasmus spec., zie aldaar. Annual Report 2015: "This bird has quite a history: in 1987, when there was only one species recognized in this group, this bird was accepted as ‘just’ a ‘Subalpine Warbler’ sensu lato (Blankert et al 1988). In a first CDNA review in 2002, following the first taxonomic changes of subalpine warblers, it was reidentified and accepted as Moltoni’s Warbler S subalpina, mainly based on the description of its calls; no photographs or sound-recordings were available (van der Vliet et al 2002). In a new review of all subalpine warbler records (cf Wassink & CDNA 2014), the CDNA decided to review this record again. The original description from 1987 of a repeatedly given loud Eurasian Wren Troglodytes troglodytes-like krrr or tsrrr call did not convince the committee that the possibility of an Eastern Subalpine Warbler S cantillans producing a rattle-like call was fully eliminated. This review led to the removal of this species from the Dutch list and this record was re-accepted as ‘just’ a subalpine warbler once again." | |
