Development of land in the southeastern United States has resulted in large sections of forest being broken into smaller, isolated fragments. Scientists studying these forest fragments have found that the smaller the forest fragment, the closer together birds build their nests.As a result of the nests being close together, which of the following will most likely happen to the birds in a particular forest fragment? A. Finding food will become easier for the birds. B. Most of the birds will lay eggs later in the year. C. Fewer birds will migrate out of the region for the winter. D. Viral diseases will spread among the birds more quickly.
D. Viral diseases will spread among the birds more quickly
