Abstract Background The role of wild birds in the dispersal of highly pathogenic avian influenza virus H5Nl continues to be the subject of considerable debate. However some researchers functionally examining the same question are applying opposing null hypotheses when examining this issue. Discussion I describe the correct method for establishing a null hypothesis under the scientific method. I suggest that the correct null hypothesis is that migratory birds can disperse this virus during migration and encourage researchers to design studies to falsify this null. Finally I provide several examples where statements made during this debate while strictly true are not generally informative or are speculative. Summary By adhering to the scientific method definitive answers regarding the role of wild birds in the dispersal of highly pathogenic viruses will be reached more effectively. Background Considerable debate remains regarding the role of wild birds in the dispersal of the highly pathogenic avian influenza HPAI H5N1 virus. Numerous articles have been published on this topic many of which lack any data which would allow critical testing relevant to this issue. .
