Sometimes you are lucky! This bird appears to be the lightcoloured female blackbird I saw last year at almost the same spot. I think they live here all the time even though I seldom see them. She burrowed for a worm and I was lucky to be able to catch this picture even if it is not terribly sharp. I mostly see these birds in the shadow under big trees. So this is as good as it gets. More winged pictures at The Bird D´Pot.
Update: Could possibly be a song trush.
