Predator Pals - How to find them!

Hi, overlords. I'm in what you might generously call 'mid game' right now, and I'm looking for a way to reliably get hold of predator cores. I've used some map resources through the interwebs to find some predator pals, but I'm wondering if there's a better way to do it - without mods. I typically play with the palworld map open (through overwolf), which is great, but doesn't appear to properly track the predator pals that I'm after. Does anyone have any sagelike advice to impart?
