Does anybody know how to deter Magpies? For the last 3 years they have taken the eggs from resident Blackbird nests. To top it all off, we had a Song Thrush sitting on a clutch, last week we heard an almighty racket in the garden, here's a Magpie flies out of the fir trees and the Thrush is going ballistic. Next day there is egg shells on the lawn and one egg left in the nest. What is the answer?, I would love to see a Blackbird or a song Thrush brood survive, but just cannot see it happening.
