Noivern is known to be extremely combative toward anything that wanders too close to it. It loves eating fruit; thus, approaching it with fruit helps to keep it calm.
So, it'd be something like a Noivern going batshit crazy, flapping its wings and screeching, then immediately becoming docile and quiet when someone gives it a berry to eat.
