Scroll down to the mating section.
Or, just read my summary: there are big masculine males with nice head and neck feathers who take territories and smaller, less masculine males and feminine males who stay in the masculine males' territories and the male males mate with the feminine males and by doing so attract females. Ok, the mere presence of more feminine males in a masculine male's territory attract females already, but they like to mate each other and it might boost the attraction. Both type of males mate with females, but females seem to prefer the feminine ones. And, when the masculine land-owner males mate with female-mimicking feminine males, both kind are likely to top.
So yeah. The females ruffs must be shippers and yaoi fan females and the males are genre savvy bisexual playboys who attract females to mate with by open display of gay fan service. And the manly males are the ones with big feathers and a harem of more feminine males.
Nature. What the heck?
