Kinda looks like a crested myna...but without the crest? So maybe some kind of Myna? Edit: The Javan Myna looks close.
well so far i think its either a myna or a blackbird. with the latest photo id think more of the eurasian blackbird also known as the Turdus merula but well im not an expert xD edit: nevermind now that i look at it theres a crest on the beak it looks more like a Crested Myna , Acridotheres cristatellus
