News Threat to Rare Birds as Avian Flu Spreads (Reuters)
PARIS - Avian flu, believed to be carried south from China and Siberia by migrating wildfowl, threatens to push some of the world's rarest birds towards extinction, conservation groups said on Thursday. Experts also voiced concern that any attempts to cull wildfowl suspected of carrying the disease could simply scatter the virus more widely by driving flocks away from their normal routes, doing more harm than good.
