This is clearly a Thrush of some sort, and probably a juvenile, but what sort exactly? Song thrush, Mistle thrush, blackbird even (they are a type of thrush, as is the Robin, but you knew that already)?

Note the yellow in the beak, the light mottling around the neck and the pinky legs (too colourful for a blackbird I reckon). But it wouldn't surprise me if it's just a blackbird.
