Three black swans that have died at a zoo in Nagoya since late last month were all confirmed to have been infected with avian influenza (H5N6).The infections at Higashiyama Zoo Botanical Gardens in the central Japan city are the second case in the country this year in which birds kept at a zoo were infected, after one at Akita Omoriyama Zoo in northeastern Japan.
The three birds died between Nov. 29 and Dec. 6.
