A series of attacks on two raptor species by Grey Butcherbirds,
Cracticus torquatus at Warnbro Sound and Halls Head, Western Australia is documented. In a further observation in the same area, a Grey Butcherbird was dropped, still alive and functioning, after being captured by a Black-shouldered Kite,
Elanus axillaris, an event interpreted as discontinued predation. The aggression by Grey Butcherbirds stimulated the raptors to move away and is assumed to be territorial defence; it may have predisposed the predatory Black-shouldered Kite to discard the Grey Butcherbird as potential prey.
