Ostriches peer out of their enclosure at Maasai Ostrich farm in Kitengela near Nairobi

Ostriches peer out of their enclosure at Maasai Ostrich farm in Kitengela, 40 km (25 miles) south of Kenya's capital Nairobi, October 22, 2005. Although no case of avian flu had been reported in Kenya, the country faced the risk from migrating birds coming from areas with the disease outbreaks, Kenya's director of medical services James Nyikal said. At least seven African countries have banned imports of poultry from countries affected by bird flu. Picture taken October 22, 2005. REUTERS/Radu Sigheti
