 Larger "Buteogallus", namely the solitary eagles, and "Geranoaetus", are much larger than other buteonines and seem to have become avian apex predators of specific habitat niches, i.e.savanna, cloud forest and páramo in South America and are thus honorary "eagles".In "Accipiter" hawks (the most species-rich accipitrid genus with nearly 50 extant species), prey is mainly other birds.
