|opmerkingen||20 October, 1cy, ringed, photographed (A Wijker, T van der Meer, R Reijnders). A record year, beating the nine from 2013. With 10 birds between 5 September and 20 October, there was an obvious autumn influx, although this largely remained unnoticed in the field: all but one were trapped. Remarkably, no less than seven were ringed at Castricum, which brings the number of records for this site to an astonishing 18. The increase of records continues, and one may wonder how much longer the species will be considered. It was first recorded only in 1990 and has been annual since 2009 (figure 3).
