A bird-watcher in Hong Kong

I just arrived in Hong Kong this afternoon, and after seeing only a few Rock Pigeons in downtown Manila in the Philippines, I was encouraged here by seeing a few Black Kites picking scraps off the surface of the bay water and some Black-billed Magpies perched on the edge of an office building roof. But birding is pretty slow here in this city too, and I was most entertained by this young man who was being entertained by a Eurasian Tree Sparrow scavenging among the walkers along the waterfront.
