Although nests were not found, a few observations of displaying and alarming birds on saltmarshes in the Wadden Sea area suggested breeding attempts here (perhaps 1-3 bp). Breeding records have become very rare in the course of the 20th century, despite increased observer-efforts (last documented nest-record in 1986).
