Wild swans are seen at Jarun lake in Croatian capital Zagreb in this February 16, 2005 file photo. Croatian scientists have detected a bird flu virus in wild swans found dead at a fish pond, the agriculture ministry said on October 21, 2005. Croatia immediately banned hunting and transport of wild fowl and poultry. "We have sent samples to Britain for further checks. There were six dead swans found in Orahovica fish pond in eastern Croatia," ministry spokesman Mladen Pavic told Reuters.
