【明報專訊】KRISTIE LU STOUT, CNN ANCHOR: Now Sweden is the latest country to report mysterious deaths of a large number of birds. Now dozens of jackdaws (寒鴉) like the one seen here were found dead on Tuesday and Wednesday. Now Swedish veterinarians autopsied (驗屍) five of the birds and say that there were no signs of infection (感染) or disease. They say the birds instead appear to have died from, quote, "sudden hard external blows."
