Magpie aggression to Crested Pigeons

["Cas and Lisa Liber" <>]

 ..or they recognise that Crested pigeons are likely to be targets for
wandering raptors and hence prefer not to have anything likely to attract
said predators to the nesting area. (from Kaplans book on the magpie)

They often do that. They probably don't see Crested Pigeons as a threat.
They are just aggressive. Three possible reasons, attempted predation, they
are showing off their aggression to their magpie family to impress them or
that they just like to keep their aggressive behaviour well rehearsed and
finely tuned.
