“The bird was first described in England by Donovan, in 1818, 
as Anas bicolor; later from the Continent by Schinz (1837) as 
Anas purpureo-viridis ; by Bonaparte in 1841, as Anas aeneo- 
rufa; Gosse named it from Jamaica, in 1847, as Anas maxima] 
Bell called it Fuligula viola in 1852, from New York, and Philippi 
in 1860 named it Anas iopareia, from Chile. 
“It thus appears to have been found in the Old World, where 
the Muscovy does not occur in the wild state, and it is not at all 
improbable that some, at least, of the crosses have been between 
domestic ducks and Muscovies; possibly all of them, as there 
is quite a range of variation in the colors of the various speci- 
mens. . . . All of the birds I have seen have been very 
large.” 
In a later letter the same correspondent adds that he has “since 
been informed that some observers have seen these birds in a 
domestic state, but our taxidermist, Mr. N. R. Wood, tells me 
that while he has seen hundreds of them in domestication, they 
all showed the characters of the Muscovy, and were probably 
crosses between the male of that species and the female of the 
mallard or the domestic bird. Possibly the wild birds that crop 
up from time to time are crosses between the female Muscovy 
and the male of the other.”
