Yes. In May 2005, highly pathogenic avian influenza (HPAI) H5N1 was detected for the first time in wild birds at Lake Qinghai, in China, where bar-headed geese (Anser indicus) died. This marked the first time since 1961 in which large numbers of wild birds have died from avian influenza. Researchers estimate that 5 to 10 percent of the world's population of bar-headed geese may have perished in that outbreak.
Most of the wild birds confirmed as having HPAI H5N1 have been sick, dying, or dead, although there are some reports of apparently healthy wild birds infected with HPAI H5N1.
The much more common low pathogenic strains of avian influenza (LPAI) do not normally cause any signs of disease.
