I suspect that this is a partially albino Rufous-bellied Thrush (Turdus rufiventris) given the location and the colour of the eye-ring.
|Sick says about thrushes:
"Albino individuals occur, being occasional but universal phenomena in cities. Albinos are usually solitary outsiders that are eliminated by predators (natural selection). They are not so rare among T. rufiventris females or in Platycichla flavipes (Yellow-legged Thrush) and are usually seen around human habitation where elimination of these individuals so visible to raptors is less likely. I have seen a completely white T. rufiventris, although it had dark eyes (not red) and yellow eyelids (Rio de Janeiro)"
