Some blackcaps that migrate to the United Kingdom have become distinguishable by certain physical and behavioral traits from blackcaps that migrate to Spain. What best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter?

Answer 1

Increases.
