Showing the speculum all silver teals except for the first on the left, a Brazilian teal
This pair of Silver Teal swam past bobbing their heads and pecking at water in a very fluid dialog. With no further actions they moved on. The male is at the back. One clue is the lateral barred design of the flank which is linear, whereas that of the female is scaled. The other one are the bars on the tail, which are finer in the male than in the female.

The differences between the male and the female of the Silver Teal are so subtle that they are considered a monomorphic species in guides. To begin with there is size, the male is bigger than the female, which is difficult to appreciate. It is easier to use differences in color or in pattern. Colour of bill strongly coloured in the male, paler in the female. The barred pattern of the male tail is finer than that of the female. The feathers on the flanks begin with a scaly pattern creamy and black and end in a barred one white and black in the male. In the female the pattern follows the same colours but all of it is scaly.
