Subtle differences between male and 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. In these two photos three can be seen: the colour of the bill and the legs and the barred pattern of the tail The male bill is strongly coloured. That of the female is paler. Male legs are yellow. Female legs are grey. The barred pattern of the male tail is finer than that of the female.
