What would happen to birds if it didn't rain for a long time?

If it didn't rain for a long time, birds would face significant challenges due to the lack of water and food sources. Many birds rely on insects, seeds, and plants that require moisture to thrive; with prolonged drought, these food sources would diminish, leading to malnutrition and starvation. Additionally, the absence of water would impact their hydration needs and nesting sites, potentially causing declines in bird populations and altering local ecosystems. Birds may also migrate to search for better conditions, which could disrupt their breeding and social structures.
