There is an annual bird photography competition in the the UK, link to website below: -

There are some decent prizes in the various categories, although I think the Warehouse Express prize vouchers can only be redeemed in the United Kingdom. There is an entry fee of 20 pounds, payable by credit card.
Entrants in the previous years of the competition have included many of europe's best-known photographers., but I'm confident Hong Kong's finest can meet the challenge !
Closing date is 30th November 2008.
