Honestly though, there's, like, little to nothing about Predator culture, biology, and history in the canon universe (which is the film universe) - almost everything we "know" came from the comics, novels, and games. That's why sources like the Yautja Encylopedia (linked above) will almost ALWAYS mix film canon and EU material. If you're really strict about canonical info, the best thing you can do is to watch the trilogy and write down everything important. I think the most revealing film was Predator 2.
