opmerkingen photographed, sound-recorded. A new publication on differences in primary projection within this species complex (Corso et al 2021) came after the sighting was submitted. During the assessments, this proved to be a valuable supporting feature. Remarkably, not a single (certain) Eastern Subalpine Warbler S cantillans was seen in 2020, of which there are four times as many records as of Western Subalpine Warbler (38 versus nine; also see next record). The former last year without an Eastern Subalpine was 2011.
