Roadside Hawk

Roadside Hawks are quite common from eastern Mexico south to northern Argentina. Often they are the most common hawk in their range. Ornithologists have described at least eleven races of this species. The photograph, taken in northern Argentina, appears to be Rupornis magnirostris saturatus, which is found from Bolivia through north-central Argentina.

The Handbook of Birds—Alive describes Roadside Hawks as being “very catholic” in their prey selection. These hawks take almost anything, mainly insects, reptiles, birds and small mammals. They are known to follow army ant swarms and eat insects trying to flee from the ants. They also hunt along the edges of grass fires, where they occasionally get singed. On the other hand, they are occasionally eaten by boa constrictors!
