Character sheet time means looking at the kukuri species info so I know what measurement numbers are sane, but I hadn't fully reread the page since they moved it to the new website and, apparently, updated it a bit:
When mating, rooks try to win their mates via flashy display of feathers and elaborate dances, akin to some bird species. It is very uncommon for two rooks to fight each other, but they might be nibbed by a displeased dove. It is common for the rooks to form pairs where the other acts as a wingman, distracting the dove when the performance is going south and allowing the bachelor to attempt again. If the bachelors are unsuccessful, it is not uncommon for them to form a bonded pair instead and take care of other pairs offspring while they are out hunting or foraging, or adopting them fully if something happens to the parents.
This is the funniest way to canonize gayhomo chicken-raptors. Thank you whoever wrote this lore blurb.
Bonus:
