opmerkingen 13 October, 1cy, photographed, sound-recorded (H H van Oosten et al). Based on Bot et al (2014), the sonagrams of the calls of this bird (figure 4) – found by one of the co-authors of the paper – matched eastern yellow wagtail and not one of the western taxa. The bird’s plumage also seemed to be consistent with an eastern bird (eg, grey bird, with long hind claw). A straightforward record then? Well... The subspecies could not be determined, and options included the much-debated Siberian Wagtail M t plexa. This taxon has not only been referred to as belonging to both the eastern and western clade, it has also been considered an intergrade by other authors and therefore invalid altogether. However, two recent papers (Drovetski et al 2018, Harris et al 2018) placed this taxon within the eastern group and this was adopted by the Dutch committee on systematics (CSNA 2019). Problem solved? Well... For Motacilla species, CSNA currently follows the phylogenetic species concept, splitting many taxa as separate species, more or less as in table 1 of Alström & Mild (2003). The CSNA is planning to decide whether the aforementioned new genetic studies may lead to changes but at present this record can only be accepted as an eastern yellow wagtail ‘sensu lato’. Despite the (sub)species could not be established, the 2008 bird for now represents the first record of a bird that belongs to the eastern clade. The CDNA welcomes the submission of reports of other photographed and sound-recorded birds from other years. Annual Report 2018.
