Quizplus · Accepted Answer

The hypothesis that the bird species switches from song to warning call whenever it sees a potential predator seems to be the most logical and straightforward explanation for the observed phenomenon. It is a common behavior among birds to change their songs when they perceive threats in their surroundings, and this hypothesis aligns with that behavior. The other two options do not provide a clear explanation for the observed changes in the bird songs.
