There are only six Falcons that can be found in the United States, but in this article we’ll be looking at the 4 falcons in Iowa.
Iowa has enacted a Wildlife action plan to keep them safe, all of their wildlife safe before they ever get to the point of becoming rare and endangered. A marvelous place for these raptors to reside in and call home at least for part of the year.
Falcons are exceptional predators. Unlike most other raptors that use their feet to kill, Falcons come equipped with a triangular-shaped ridge “Tooth” located on the outside of their beak used to kill prey quickly and efficiently. Couple this with their killer speed and their ability to swiftly change direction, and you have a magnificent hunter.
