Song Thrush?

I'm not sure if this is a Song Thrush or a female Blackbird. I bought a new birdfeeder and moved this one from a hanging position to a standing position because the Robins and the Blackbirds are unable to hover long enough to feed from any of the bird feeders I have.  I thought the Robin might have worked out that it could fly inside the cage and sit on the bottom of it when it was hanging, but it only did it a couple of times, so I decided to sit this feeder on top of the bird bath and that has worked out well. The Magpies are too big to get right inside.  I have filled this feeder with a mixture of nuts and seeds and seeded bread all held together with melted butter and stollen cake
