The recent discussion prompts me to ask whether in species where males help raise the young, do we know whether drabness in males is more common? A drab male would be more likely to be around to help, so females might develop a greater preference (tolerance?) for drab males.
I believe that this is indeed the case. As I recall, it's also the case that when the male is more involved in the rearing of offspring, there is also less sexual dimorphism in general. The boys start looking more like the girls.
The Emu is a good example of this I think.
Wiki has quite a good article on them.
