Answer:
A.
Explanation:
Due to the early arrival of spring, the populations will increase since warmer temperatures are generally beneficial to survival. Blue-winged warblers tend to migrate south when winter arrives in order to survive and come back when spring begins to arrive once again. Since spring is arriving early it allows the population of warblers to have more time to take advantage of, this would allow them to reproduce more often and thrive on the excess amount of resources that they can take advantage of. All of these factors drastically increase their survivability.
