Prevent the Spread of Avian Influenza Avian influenza, known as “bird flu,” is a viral infection that spreads easily and quickly among birds. Your small flocks and pet birds could be at risk of catching bird flu when wild birds migrate to and through Canada in the spring and fall months, as wild birds naturally carry influenza viruses. Your chickens, pet birds and other flocks could be at risk of catching bird flu when they have access to the outdoors. Infected wild birds, such as ducks and geese, can spread the disease by direct contact with your birds or by contaminating your birds’ environment. This includes ponds and other bodies of water. There is currently no treatment for infected birds. Signs of Infection include: lack of energy, movement or appetite decreased egg production swelling around the head, neck and eyes coughing, gasping for air or sneezing nervous signs, tremors or lack of coordination diarrhea sudden death For more information on preventing the spread of avian influenza in wild bird, please visit Canada.ca/Avian-flu
