RSPB Big Garden Birdwatch

Today we did the RSPB big garden birdwatch. We got a few birds visiting during the hour we were recording, but all of them were common ones, starlings, blackbirds, thrush, collared doves and a wood pigeon. Did anyone else take part, and have any interesting spots during the hour?

Since we started feeding them the number of birds visiting has increased, which is pleasing, but I would still like some of the more colourful birds to visit, we have had no tits or finches at all yet. We do get a robin, sparrows and have had a few visits from a dunnock and a pied wagtail a few times too but they didn't appear today while we were counting. 

We also get a large black bird which I think is a rook as it has a light grey beak and from looking at bird identification, all the other large black birds like crows, and ravens, have black beaks. However they also say that the rook is seldom seen alone and is a social bird, and this bird only ever visits on it's own. I must try and get a photo of it and then maybe some of you can help me identify it. Does anybody have any other ways to differentiate between the larger black birds? 

Here's a photo from today, mainly starlings  but at the end of them you can just spot the thrush and the blackbird.
