What is a principal threat to raptor populations?

The principal threats to raptor populations primarily stem from habitat destruction and climate change, making the choice of both A and B valid. Habitat destruction can occur from various factors, including urban development, agriculture, and deforestation, all of which lead to the loss of nesting and hunting grounds critical for raptors. As human activities continue to encroach upon natural landscapes, raptor populations face increasing pressure on their habitats.

On the other hand, climate change impacts raptor populations by altering their ecosystems. Changes in temperature, weather patterns, and prey availability due to climate fluctuations can affect raptor breeding success and survival rates. These shifts can disrupt food chains and force raptors to adapt to new conditions that may not support their survival.

While captive breeding plays a role in conservation efforts for some raptor species, it is not considered a principal threat to raptor populations at large. Instead, it is often employed as a strategy to help bolster numbers in declining species. Thus, the combination of habitat destruction and climate change collectively poses significant threats, underscoring the importance of addressing both issues to ensure the health and stability of raptor populations.
