Well for one they're smart enough to do so and it can increase chances of survival when on their own and also they're highly social animals. Ultimately a Great Jaggi wants one thing and thats to lead a pack and since they're resourceful and intteligent they'd most likely take any chance at becoming a leader even if that means partnering up with a sibling or complete stranger. Also Jaggi raptors have similar social system just like a pride of lions with the females staying together for most of their lives while the males eventually leave to find a new pack(in this case) to lead.
