So, despite our efforts to deter them a pair of blackbirds have nested very low down in the hedge in our back garden. The reason we tried to stop them when we first noticed them is because of our 2 cats which will just terrorise them from now until all the babies have fledged. Both the male and female have been going in and out the hedge this evening with beak fulls of worms. Could the eggs have hatched already? Is it too early? They are both very protective of the nest, I can't go into the garden without them both having a go at me, they are so loud. When the cats are out there the blackbirds get really loud, I'm trying to keep the cats in when the birds are active but it's not easy. I was just out there and one of the cats was up on the fence, the female blackbird was in the tree telling us off then she dive bombed the cat on the fence! It's going to be a stressful few weeks.
