Peregrines, distinguishing male from female (1 Viewer)

Other than size, how can I distinguish the male from the female? We have a nest cam that I have been watching, here in KC, with four eggs, But I see no difference between the two adults. Any thoughts?
 
As Rafael has said, size and proportion. I'm sure I read a while back that the male has more extensive white on the chest and belly.
 
Also, the cere is different in colour when the pair are in tip top breeding g condition, the male being more yellow.
