Question

how does the behavioral adaptation of making nests on building ledges and roofs most likely increase the likelihood of their species surviving?
a. high nests reduce the number of predators that can reach the baby birds.
b. high nests increase the number of parasites that are present.
c. high nests allow birds to easily collect water when it rains.
d. high nests allow birds to remain cool in the heat of the summer.

Explanation:

Building ledge/roof nests are elevated, which limits access from many ground-based or low-lying predators. This protects baby birds, boosting survival. Option B is harmful, while C and D are not reliable or primary benefits of this nesting behavior.

Answer:

A. High nests reduce the number of predators that can reach the baby birds.
