A bird sanctuary in Greater Manchester is reporting a big fall in visitor numbers due to fears over avian flu. The Three Owls is open 24 hours a day tending to the thousands of injured birds brought to its doorstep every year mainly from the North West. About 10,000 people annually visit the sanctuary in Norden, Rochdale, helping to provide much-needed income. However, manager Nigel Fowler said that visitor numbers were dramatically down for this time of the year.
