maccoa
Maccoa, an alternative spelling of Macao, China (Portuguese Macáu).
● An erroneous toponym. Despite its substantive and scientific names the Maccoa Duck is found only in tropical Africa. Clinning 1989, records that the Afrikaans names for the domestic Muscovy Duck and the Spur-winged Goose are Makou and Wilde makou respectively, but that Makou is of Chinese origin (Oxyura).
