CLEAN : Keeping the rare US whooping cranes

The video discusses the use of costumes to minimize human interaction with whooping cranes, the genetic bottleneck they experienced, and the challenges they face in reproduction due to environmental factors like biting flies. It also covers training methods and bird behavior, highlighting the commitment required in this field.

Why do conservationists wear costumes when working with whooping cranes?

• To entertain the birds

• To keep warm in cold weather

• To prevent the birds from recognizing humans

• To protect themselves from the birds

What is a significant consequence of the genetic bottleneck experienced by whooping cranes?

• Greater resistance to diseases

• Increased population size

• Loss of genetic diversity

• Improved reproductive success

What is one reason for the poor reproduction rates at the original release site?

• Insufficient nesting materials

• Lack of food resources

• Harassment by biting flies

• Predation by larger birds

How do conservationists encourage whooping cranes to follow them?

• By mimicking bird calls

• By offering them treats

• By using bright lights

• By using loud noises

What is one method used to guide whooping cranes during conservation efforts?

• Driving vehicles

• Flying ultralight aircraft
