The relationship between the biological distinctive features of wild migratory birds and the ecology of influenza A virus in nature is revealed. On the basis of literature data and personal research, the im-portance of viral carriers with regard to the prevalence of the virus among the wild birds species, the seasonal variations, age-rated susceptibility, subtype distribution and the transmission in wild and domestic birds are reviewed. Key words: avian influenza virus, subtypes, epidemiology, wild birds Since the isolation of the first avian influ-enza viral (AIV) strains, a number of questions related to their persistence in ecosystems, the transmission mode among wild, domestic birds and mammals have appeared (Stallknecht, 1997). Some of them are already solved, others are yet unexplained.
