Prestwich (1960) and Gray (1958) have concluded, mirroring Delacour and Mayr (1945) and Seth-Smith (1922), that the Mandarin Duck is unable to hybridize, even with its nearest living relative the Wood Duck. After reviewing the literature, however, I listed (1960) the Mandarin Duck as having probably hybridized with the Wood Duck, and also mentioned the possibility of hybridization with one or more species of Anas. Since then I have been hopeful that actual specimens of Mandarin Duck hybrids might be located to substantiate this vulnerable position, and it is now possible to report on some probable hybrids.
