Every year,environmental signals in Africa cause flycatchers to return to the Netherlands to breed.When they arrive,they depend on freshly hatched caterpillars for food.Global climate change has caused the caterpillars to hatch earlier in the Netherlands,but the environmental cues in Africa remain the same.Now,when the flycatchers return to the Netherlands,the caterpillars are no longer available as a food source.Which of the following is most likely to happen to this species of flycatcher?

Question

Quizplus · Accepted Answer

The flycatchers may adapt to the change in the availability of caterpillars by utilizing other food sources if they possess genetic traits that aid in utilizing different food sources. This would allow the species to continue to breed and survive in the Netherlands despite the earlier hatching of caterpillars. However, it is unlikely that the flycatchers will learn to fly to the Netherlands earlier or remain in the Netherlands instead of returning to Africa, and it is also unlikely that the species will be unable to utilize new food sources.
