FAO says human activities, not wild birds, spread H5N1
The UN’s Food and Agriculture organisation says it is unreasonable to blame wild birds as the source of H5N1, in the absence of rigorous research into their role in the ecology and dynamics of the virus. (Avian flu: Don’t place all the blame on wild birds, 22 May 2006).
Migratory birds are not really a threat.

Mystery shrouds loss of migrant birds
Mystery is surrounding the huge declines of birds that migrate thousands of miles from Africa to Europe each spring.
Scientists fear that their dwindling numbers may be a warning of widespread environmental damage.
Climate change, drought and desertification in Africa, and massive pesticide use on African farmland may all be to blame for the declines of once common UK birds such as the Spotted Flycatcher Muscicapa striata, Northern Wheatear Oenanthe oenanthe, Wood Warbler Phylloscopus sibilatrix and European Turtle-dove Streptopelia turtur, a BirdLife Europe-wide study led by the RSPB (BirdLife in the UK) concludes.
At the same time, birds such as the European Roller Coracias garrulus, Pallid Harrier Circus macrourus and Lesser Kestrel Falco naumanni have also vanished from regular breeding sites on the continent.
All three are now classified as near- or globally threatened.
