More than 1,000  http://phys.org/tags/wild+birds/" rel="nofollow - wild birds , mostly geese, have been found dead in the Mighan wetland in central Iran, the environmental protection organisation told state news agency IRNA on Monday.

IRNA said 63,000 chickens, along with 800,000 fertilised eggs and day-old chicks, were culled at a farm in Qazvin province in recent days after an outbreak of the deadly H5N8 and H5N1 strains of the disease.

That adds to the 725,000 birds destroyed since mid-November across the country following nine  http://phys.org/tags/flu+outbreaks/" rel="nofollow - flu outbreaks , according to a report from the World Organisation for Animal Health released last week.

Licenses for bird shooting have been suspended due to fear of infection by  http://phys.org/tags/migratory+birds/" rel="nofollow - migratory birds , and people have been advised not to buy game birds at local markets.

Despite a small number of human deaths in different countries over the years, the disease is mostly a risk to other birds, spreading rapidly and killing large numbers.

However, scientists have raised concerns that bird flu strains could mutate to be transmitted between humans.
