Mallard, Anas platyrynchos
10 July 2011
This male is in eclipse plumage having been flightless for a period of weeks. Mallards, unlike most species, undergo a complete moult of flight feathers at one time and form "bachelor clubs" of flightless males. This picture, taken at Humber Bay Park East in Toronto, ON shows the characteristic head colour of the male growing back and replacing the female type colouration which prevailed during the flightless period.
