How do Birds get onto an island? It must be by flying? http://www.guardian.co.uk/society/2005/oct/20/health.birdflu

Taiwan today became the latest country to announce the discovery of bird flu. Authorities said the H5N1 virus was found among birds on a Panama-registered freighter that was stopped by the Taiwanese coast guard on October 14. Spokesman Sung Hua-tsung said the freighter was carrying 1,037 smuggled birds – consisting of 19 species – all of which originated in China.
