Rob and Martin  have referred to a research article on translocation of attacking magpies.  [D.N. Jones & T. Nealson (2003) Management of aggressive Australian magpies by translocation. Wildlife Research 30(2):167-177].
Part of the abstract reads:
A total of 141 magpies were translocated, 31.7% of all birds investigated. Of these, only five (3.5%) returned to the place of capture, and 22 (15.6%) were resighted elsewhere; there was no evidence of 'homing'.
With regard to "there was no evidence of 'homing'" maybe it is because there is no longer a home to go to. 
Darryl Jones has written in the July/August 2003 Interpretive Birding Bulletin [vol 4, no 4] in regard to the female left with young to rear.
"......... Needless to say, the first signs were both impressive and ominous: almost all females had a new male in place within a day (and sometimes within hours) of the removal of their erstwhile mate.  In all but one of the new pairs, the replacement male was not a neighbor or otherwise mated and territorial bird.  The males simply appeared, as though out of thin air.  As observed in other species there is apparently an invisible underworld of floaters, mate-less males that skulk around in the shadows and edges of established territories without being seen but ready to grab an opportunity should one arise"
And the step-parental magpies were approximately twice as diligent in chick provisioning as had been parental males.
