Migratory Birds and Disease Control

The video discusses the migration of birds and the associated risks of spreading diseases like avian influenza. It highlights the economic and health impacts of such diseases on humans and animals. The FAO IAEA division's efforts in using nuclear-related techniques to prevent disease outbreaks are explained. These techniques help in identifying pathogens early and tracking migratory patterns of birds, providing a proactive approach to disease management. The advantages of these techniques, including their accuracy and non-invasiveness, are emphasized.

What is one of the main reasons birds migrate?

• To seek overwintering areas or safe nesting areas

• To find new habitats

• To explore new territories

• To escape predators

What is a significant risk associated with migratory birds?

• They increase competition for resources

• They can damage crops

• They may carry pathogens harmful to humans and animals

• They can cause air traffic disruptions

What disease is closely linked to migratory birds?

• Swine flu

• Avian influenza

• Foot and mouth disease

• Mad cow disease

What has been a major consequence of avian influenza outbreaks?

• Higher demand for bird feed

• Increased bird populations

• Improved farming techniques

• Death or culling of millions of poultry and pigs

Since when has the joint FAO IAEA division been working to reduce disease risks in farm animals?

• 1994

• 1974

• 1964

• 1984

What is a specific focus of the FAO IAEA division's work?

• Developing new bird species

• Building bird sanctuaries

• Identifying pathogens before disease outbreaks

• Creating new vaccines

What can stable isotope analysis of a bird's feathers reveal?

• Where the migrating bird began its journey

• The bird's diet

• The bird's health status

• The bird's age

How can researchers track migratory birds and identify virus carriers?

• By observing their flight patterns

• By analyzing their droppings

• By using stable isotope analysis and regular techniques

• By tagging them with GPS devices

What is a key advantage of nuclear-related techniques in disease monitoring?

• They are easy to implement

• They are cost-effective

• They are highly accurate and non-invasive

• They require minimal training

How do nuclear-related techniques contribute to disease control in wild birds?

• By reducing the risk of diseases spreading

• By improving bird habitats

• By increasing bird populations

• By eliminating all pathogens
