Beginning in October 2018, a male Mandarin duck (Aix galericulata) has been swimming around the Pond in Central Park. This duck has become a bit of a celebrity, because Mandarins are not native to the Western Hemisphere, so any duck hanging out has to be an escapee or a release.
Genus Aix
I videotaped Mandy on October 28, 2018, showing the little dabbler hanging out with the mallards.
This is not the first time a male Mandarin duck has hung out in Central Park. I photographed a male Mandarin duck in the Central Park Zoo on March 18, 2016. (I haven't returned to the zoo recently, so do not know if this duck is still in residence.) Both the 2018 and 2016 ducks are banded, but with different bands.
The Mandarin duck is one of two ducks in the Aix genus, the other being the wood duck (Woody the Wood Duck, Prince of the Pond, resides year-round at the Pond).
