Eurasian Wigeon Breed in the Aleutian Islands, Alaska
Jack J. Withrow
ABSTRACT: In June 2022, while collecting in the Aleutian Islands, Alaska, for the University of Alaska Museum, I observed at least three broods of Eurasian Wigeon (Mareca penelope) on Amchitka Island (51.39° N, 179.26° E) and two broods on Adak Island (51.92° N, 176.64° W). So far as I have been able to determine the specimens collected from them represent the first actual documentation of nesting by the species in North America.
