Why can islands support many beetles but few hawks?

Islands often have limited resources and space, which can support numerous beetles due to their smaller size, adaptability, and ability to exploit various ecological niches. In contrast, hawks are larger, require more extensive territories for hunting and nesting, and need a stable food supply, typically found in more diverse ecosystems. The absence of these resources on islands limits the number of hawks that can thrive there, while beetles can flourish in greater numbers due to their resilience and reproductive capabilities.
