Blackbird nest

We've had a pair of Blackbirds nesting in the Mahonia bush, from building to feeding young the last eight days. We couldn't see the nest as it was so well hidden. A Grey Squirrel was showing interest in the site yesterday and I saw it off a couple of times. This morning it's not looking good. The adults are there but they're not fetching food in, just sitting in the nearby tree 'clucking'. Three Grey Squirrels in the trees at the back are the are the chief suspects. Grrrrr !!!

Plenty of food was coming in for the chicks last few days
