I think I am right in saying that all of the recorded Turdus thrushes in HK will not have pale tips to the coverts in adult plumage except Chinese Thrush.(Note this is not true for Zootheras or Rock Thrushes.)From your fab picture , the greater coverts appear pale tipped in keeping with your suggestion that this is a first winter bird.
