I have a mature pair and was wondering if there is any visable difference between male and female? they met up at dusk but all day stay apart.

That sounds just like my pair, and i have no idea which is the male or female till they have eggs.

The males get a really square jaw when they are holding eggs. That's how I finally figured it out.
