Two of the spells in Harry's arsenal can down Pegasus untill either a) Harry dies or b) the counterspell is used. And the communication doesn't matter as much (unless the pegasus is one hell of a lot smarter than he is or can see where he can't) b/c the Firebolt is not alive, maening that Harry has total control. Animals can be startles or incapacitated. The broomstick would have to be destroyed.
