There is not likely to be an effect based on a warming climate.
Their eggs will hatch later.
The range shifts uphill over generations.

Answer 1

Bird populations on mountainsides are likely to respond to a warming climate by shifting their ranges uphill over generations. As temperatures rise, suitable habitats for many bird species may migrate upward to higher elevations where it is cooler. This movement allows them to find conditions more favorable for survival, such as optimal temperatures and food availability. Therefore, the correct option is:

**The range shifts uphill over generations.**
