Hi Dan,
Proabably not actually, I'm afraid.
Hong Kong is not well-provided with shops that sell bird books.
The stocking policy with regard to brd books of otherwise fairly good bookshops like PageOne and Swindon's is unfathomable - they seem to think there's massive demand here for very ordinary books on "Common birds of a North American/British/European Garden", or the like. In fact the books stay on their shelves for months/years, next to the books on dogs, cats etc!
If you need such books you have to get them by mail-order/Internet from overseas. Or look in bookshops in Singapore (the really big one with the long Japanese name, Borders, or the excellent bookshop in the Botanical Gardens there).
Having said all that if you haven't tried Swindon's in TST or Kelly and Walsh in Pacific Place, you might just be lucky there.
