What evidence in the video supports the idea that an introduced predator caused a change in the populations of kiwi and other flightless birds?

Answer 1

One piece of evidence in the video that supports the idea that an introduced predator caused a change in the populations of kiwi and other flightless birds is the statement by the conservation biologist that the population of kiwi has decreased by 74% in the last 20 years, and the number of kiwi chicks surviving to adulthood has dropped by 90%. This suggests that something is significantly impacting the kiwi population, and the introduction of predators like stoats and ferrets could be a likely explanation for these declines. Additionally, the footage of a stoat attacking a nesting kiwi and killing its chick provides a visual example of how these predators can directly impact the survival of kiwi and other flightless birds.
