In my experience, 5th Gen Kush definitely flies more often then regular Kush in other games (Although Rusted Kush flies more then New World Kush).

As for Poison, apparently, it does lower New World Kushala's wind aura by a level, but in World, the Wind Aura has five levels, and Kushala can roar at anytime to raise it's Wind Aura by a level; even while poisoned.
