Wow, great record!

I agree with Koel that this looks more like a Northern Wheatear, based on the dark mask, dark wings, horizontal posture and apparently fairly extensive white in the tail.

It's a species that has often been predicted as a potential vagrant to Hong Kong. I'm sure many people will be frustrated that this bird is 'so near yet so far' on the other side of the Pearl River Delta. But congratulations to Macau Aves Society on such a great find!
