Recently I twice saw a blackbird pecking at a rat bait sachet on our patio. Pest control guy who baited the box says a blackbird was seen going into the bait box and coming out with the sachet - something he said he has never heard of before. I don't think a bird would go into a dark place, where it cannot flap it's wings if it needs to get away quickly, then find a sachet 'around the corner' where they are placed in a bait box and pull it out backwards. I suspect a neighbour is removing the sachets from the bait box as he moans about us feeding birds. Any comments would be appreciated.
