The Eurasian Wigeon was not listed by Clapp (1999) and has apparently not previously been reported from Kwajalein Atoll. The photos below are from Christina Sylvester, who found one individual on Kwajalein Island in October, 2018. This has been a very wet year for Kwajalein, and in previous wet years, the various duck species that stop on the island tend to stay longer.
