Other hawks that might occasionally prey on prairie dogs include:
* Swainson's hawk: A common hawk in the Great Plains, but not as specialized for prairie dog hunting as the ferruginous hawk.
* Red-tailed hawk: Found in various habitats, including grasslands, but less common in areas with dense prairie dog colonies.
It's important to note that while these hawks are known to eat prairie dogs, their diet varies depending on availability. They also prey on other small mammals, reptiles, and amphibians.
