<P> The magpie is generally sedentary and territorial throughout its range , living in groups occupying a territory , or in flocks or fringe groups . A group may occupy and defend the same territory for many years . Much energy is spent defending a territory from intruders , particularly other magpies , and different behaviours are seen with different opponents . The sight of a raptor results in a rallying call by sentinel birds and subsequent coordinated mobbing of the intruder . Magpies place themselves either side of the bird of prey so that it will be attacked from behind should it strike a defender , and harass and drive the raptor to some distance beyond the territory . A group will use carolling as a signal to advertise ownership and warn off other magpies . In the negotiating display , the one or two dominant magpies parade along the border of the defended territory while the rest of the group stand back a little and look on . The leaders may fluff their feathers or caroll repeatedly . In a group strength display , employed if both the opposing and defending groups are of roughly equal numbers , all magpies will fly and form a row at the border of the territory . The defending group may also resort to an aerial display where the dominant magpies , or sometimes the whole group , swoop and dive while calling to warn an intruding magpie 's group . </P>
