Prayer bird species range from munias, Japanese white-eye, white-rumped
munia and tree sparrows costing as little as HK$4 (US$0.50) each, to the more
expensive azure-winged magpies and Mongolian larks, are imported from China. The
prayer birds are released en masse at Buddhist religious rites, and could spread
bird flu to poultry, experts say.
"We really have to seriously consider this possibility of prayer bird
infection," said Malik Peiris, a virologist and leading bird flu expert at the
University of Hong Kong. "In
Hong Kong, there is no H5N1
activity in poultry. So for this bird that was found dead, the question is how
it got infected?"
While the Hong Kong government tightly regulates poultry imports, laws for
wild bird imports are much more lax, making it a potential crack in the city's
bird flu defences. The territory had recently banned imports of poultry from
Japan after a fresh outbreak of bird flu there.
Richard Corlett, a professor of ecology at the University of Hong Kong,
said the trade in wild birds was on a much larger scale than previously thought,
with at least half a million birds freed by Buddhists in 2005, sometimes
thousands at a time.
Hong Kong's concerns come as the European Union passed new laws banning
imports of wild birds on health and animal welfare grounds, a move which Corlett
said the Hong Kong government should follow.
"There's a great deal of reluctance to acknowledge this is a problem ...
You can go and buy 10,000 budgerigars and release them in a country park and
there's nothing to stop you doing that," Corlett said.
The government has not said whether it would consider a ban on wild bird
imports but has urged Buddhist organizations not to release such birds in
future.
