For the past 2 years, we have had blackbirds nesting in our clematis and it has been lovely to see the parents going in and out, feeding them etc. Today I was looking out of the window and saw the blackbird sitting with grubs in its beak waiting to go into the nest. Coming up behind him along the fence was a grey squirrel. The blackbird flew away and the squirrel went straight into the clematis. By the time I got outside it was too late... The squirrel had gone and so had the last of the chicks. I know that it's nature, but still so sad. I didn't realise squirrels even ate meat, but I have just searched the internet and it is quite common for them to steal eggs and eat chicks. Now I know why they're called tree rats.
