Been enjoying seeing all sorts of birds congregate in our garden and the variety has really increased this year. Was hoping for tits and lo and behold one appeared only to be pecked to death and carried off by a magpie. By the time we raced out it was gone. So sad a song thrush had been following me around as I tidied up from gardening. Worried all the other birds will be scared off now. How do we deter magpies.
