Many bird species exhibit sexual dimorphism, i.e., male and female
have differing appearances which can be quite subtle.
There are two ways of telling male and female Australian Pied
Oystercatchers apart. When seeing a pair together, the length
of the bill is the easiest diagnostic - the male, left, has a
shorter bill than the female. Up close, one can also see that
females have a black dot in the lower-front quadrant of the
red iris that is absent in the male.
