I have acoustic animal ‘scarers’ as I love seeing the birds in my garden. They don’t work on birds of prey! A couple of weeks ago some form of pigeon was food for the raptor, on Sunday morning it was a blackbird. It had been plucked, decapitated and both breasts had been consumed. Nature, red in tooth and claw. The birds of prey must eat too. Still a little sad. The odd thing is I still have a pair of blackbirds visiting my garden eating worms and insects. They seem to just accept it.
