Eurasian Wigeon, Strybing Arboretum, Golden Gate Park, Nov. 16, 1997. Most of us confidently identified this bird as a female. It then proceeded to molt into full male plumage. This bird is still present, being seen most recently at nearby Stow Lake. Note telltale gray emerging on the sides of the breast. True female Eurasian Wigeons are detected far less often than males in California probably because of difficulties in identification.
