Spot the difference

Sexual dimporphism, that is the existence of clear and obvious differences between males and females, is obvious in some species of birds but not so in others. Two of my woodland favourites illustrate this, or more correctly, sexual dichromatism. Male and female Spotted Pardalotes are distinctively different whereas every Jacky Winter looks identical, irrespective of the sex.

Male or female – your guess is as good as mine!
