Mandy, Feisty, the Mandarin Duck
By Linda Swanson
My story begins on November 17, 2014 in Golden Gate Park at the inlet curve of Stow Lake. Annually, one or two Wood Duck arrive and take residence among entwined branches at this spot. It was a pleasant surprise to see there was a female Wood Duck on that sunny morning. My thoughts were to post this sighting to the SF Birds forum. As I took confirmation iPhone photos, a walker stopped to see what I was doing. We chatted about her sister’s fondness for Wood Ducks and how nice it was to see one here in our city. I dashed home to compose my posting, reviewing my photos alongside the National Geographic Field Guide to the Birds of North America, but the ID markings around the eye were not a match for Wood Duck.
I was perplexed.
I turned the pages to the exotic ducks section and was surprised to see this appeared to be a female Mandarin Duck. My ornithology instructor, Joe Morlan, taught us a critical thinking approach to IDing birds. He saved me from a hasty and incorrect report.
Here’s a mantra Joe includes beneath his public postings about birds: “It turns out we’re very good at not seeing things” – Jack Hitt

The Wood Ducks that populate Stow Lake each year are only there for summer months during while they molt. Then they migrate on. But this Mandarin Duck could not be a naturally occurring species as its range is scattered from Russia to Japan. (The Cornell Lab of Ornithology, “Birds of the World”).
So the question remained: how and why did this female Mandarin Duck arrive at Stow Lake?
In the days that followed, the Mandarin Duck took up residence on the opposite side of Stow Lake that provides a nice habitat for the many ducks living there. It became the highlight of my daily run to see the Mandarin (whom I named Mandy). Eventually, I discovered her missing left wing feathers. I brought up the Mandarin in my ornithology class for discussion and learned of previous occurrences of Mandarin Duck nearby, one a decade prior at the Palace of Fine Arts, and in Sonoma County in the 1980s. Where had Mandy come from?…
