Look into my eye - Female Black Oystercatcher

If you zoom into this Black Oystercatcher's eye, you will notice a dark speck right next to the black pupil of the bird. This is the female. Males do not this large speck.

 

Due to their almost identical plumage and size this is really the only way to differentiate sex of this bird.
