|opmerkingen||3-9 December, Zanddijk, Zuid-Eierland, Texel, Noord-Holland, first calendar-year male, photographed (fam van den Dries, A Wassink et al; Ebels et al 2018; Dutch Birding 40: 67, plate 84, 155, plate 209, 2018). The recent history of this taxon is remarkable. The January record was part of the autumn influx of 2016 that already delivered three birds. The bird appeared to be very weak and it was speculated to have died after it was last seen. With two more birds in late autumn 2017 and – as will be mentioned in next year’s report – another one in early 2018, no less than seven were found within 15 months’ time (plumage analyses proved them to be different individuals). The 2011 bird was not accepted at the time but new identification insights (van der Spek & Martinez 2018) led to the acceptance of this now second record. Therefore, within two years the number of records increased from three to no less than 11! A previously not accepted report on Schiermonnikoog, Friesland, on 31 October 2005 is currently being reconsidered. Annual Report 2017.|
